Tory Johnson, GMA Workplace Contributor, discusses work-from-home jobs, such as JustAnswer in which verified Experts answer people’s questions. I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time.
A word about this checklist before you start: it is arranged in a specific order to put the most likely failure items first. Most of the items are electrical in nature, so a test light, or even better, a voltmeter, is helpful to be sure they have power to them.
A.) MSD, Crane, or other ignition box if present - Bypass it and return to stock configuration if possible. 86-93 models only: EEC relay next to computer - look for 12 volts at the fuel injector red wires. Both 86-93 and 94-95 models: No 12 volts with the ignition switch in the run position on the fuel injector red wires. 86-93 models only: Fuse links in wiring harness - look for 12 volts at the fuel injector red wires. Ignition fuse links may be replaced with an inline fuse holder and 5 amp fuse for troubleshooting purposes. K.) Engine fires briefly, but dies immediately when the key is released to the Run position. B.) Fuel pump power relay – located under the driver’s seat in most stangs built before 92. The fuse links for all model years 86-93 live in the wiring harness near the starter solenoid. A noid light available from any auto parts store, is one way to test the injector circuit to see if the injectors are firing. I like to use an old injector with compressed air applied to the injector where the fuel rail would normally connect.
B.) Pull an injector wire connector off and look for 12 volts on the red wire when the ignition switch is on. The negative lead sometimes fries and it will also take out the trace on the circuit board, which you will also have to repair! Interesting thing--when I move the distributor back and forth to check the fuel pump, there is a tick, tick, tick sound somewhere in the engine bay. Ohms measures at the computer with the computer disconnected, or at the sensor with the sensor disconnected.
It seems more like a lack of fuel if you're cranking it that much and not soaking plugs.
For the exterior door handle, you have to pull the liner out to access the nuts holding the handle to the door. If you find the oil caked around the exhaust, you may have a leak into the engine, possibly through the O-rings.

I know there are also coils for ballast resistors and then again there are coils for systems without resistors, and some you cannot swap.Let me see if I can find out any more info on that.Do you have any more info such as part numbers, etc? The 98 yamaha warrior 350 are manufactured by a Japanese firm known as the Yamaha Motor Company Limited. 98 yamaha warrior 350 are built with the best technology than most of the other motorcycles available in the market.

They will also show the amount of voltage drop from the ground (-) terminal on the alternator. It may not display this or other websites correctly.You should upgrade or use an alternative browser. The computer has its own dedicated power ground that comes off the ground pigtail on the battery ground wire.
Then pull the air duct off at the throttle body elbow, open the throttle, and spray the ether in it.
Check fuel pressure – remove the cap from the Schrader valve behind the alternator and depress the core.


The noid light plugs into the fuel injector harness in place of any easily accessible injector. I hook the whole thing up, apply compressed air to the injector and stick it in a paper cup of soapy water. This will shut off the injectors, since the computer uses this strategy to clear a flooded engine. If you removed the distributor, there is a good probability that you installed it 180 degrees out of time.
I have checked the voltage on the ECT and it reads 4.66 volts, but would that cause a no start problem? The fuel pump relay is located under the Mass Air Meter on Fox bodied stangs built after 91. During crank I was getting a popping sound and heard that could be due to timing being too advanced, so slowed it down bit--no more pop, but no start either. Watch the plastic clip, it can be tough to get off, if it falls off or you loose the control rod down the door, you will have to remove the liner to get it back.
PO 441, and PO 446) can cover anything from a bad gas cap to cracked or leaky vacuum lines to a flooded or cracked charcoal canister. See after he put the motor in and all the MSD parts The Mechanic said I didn't need the Ballst resistor since it was ELECTRONIC IGNTION. The company began its operation in 1955 and has since then produced other motorized products such as 98 yamaha warrior 350 and bicycles, scooters, and boats. I had real doubts about this website but your promptness of response, quick followup and to the point answer with picture was incredible. If the TFI is working properly, the test light will flash when the engine is cranked using the ignition switch. Due to it's proximity to the battery, it may become corroded by acid fumes from the battery. Hold the switch in the crank position: if it continues to run there is a problem with either the ignition switch or TFI module. To trick the fuel pump into running, find the EEC test connector and jump the connector in the Upper RH corner to ground.
Remove the vacuum line from the regulator and inspect for fuel escaping while the pump is running. When the engine cranks with the ignition switch on, if the injector fires, it makes bubbles. Make a second measurement using the battery post as the ground to eliminate any ground problems.
Sometimes a EVAP code is triggered by a bad catalytic converter - but usually you'll get a trouble code showing fuel trend issues as well. If it is definitely the canister - you should be able to pick one up anywhere from $150 to $250 brand new.
They are suitable for use in all terrains and are, therefore, multipurpose motorcycles suitable for use in various tasks. By repositioning the voltmeter test leads, the point of high resistance (voltage drop) can easily be found. Jumping around will possibly cause you to miss just what you need to see to find and fix the problem. Jumper the screw to the big bolt on the starter solenoid that has the battery wire connected to it. See paragraph 5A – Using a noid light will tell if the PIP is working by flashing when the engine is cranking. On Mass Air Conversions, the signal lead that tells the computer that the fuel pump has power may not have been wired correctly. To trick the fuel pump into running, find the ECC test connector and jump the connector in the lower RH corner to ground.
A trim removal tool or even a putty knive can be used to pop the clips around the perimeter of the door panel. Bad grounds in sensors also causes issues - but those are generally much harder to find in an intermittent issue, unless you have some circuit that is completely shorted out. Getting to the canister could be an ordeal - it is tucked next the gas tank right next to the rear subframe. You have to because it is oil filled.Second, how many volts is your alternator putting out?


They are cost friendly, as well as, stress free because their spare parts are readily available.
If 12 volts is present in the Run position at the ignition switch but not at the coil, then the fuse or fuse link is blown. Sometimes these problems go away on their own or are fixed while checking on other components.
The 98 yamaha warrior 350 became global when they took part in the Catalina Grand Prix in 1956.
It may not be completely accurate, but you will have some clue as to how much pressure you have. Just pry a little at a time, use a flashlight to take a peek there and you should be able to see the clips you need to pry out. By 1980, the manufactures introduced the four stroke engines that were environmental friendly. Just be careful of the plastic vapor barrier - if you pull it off slowly and easily - it can be reused. Start the engine, let it warm up to normal operating temperatures, then turn the engine OFF .
Start the engine, then place the blower on HIGH, and turn on the high beam headlamps and rear window defogger.
To test the positive (+) circuitry, perform the following: Touch the negative (-) lead of the voltmeter directly to the positive battery post. Touch the positive (+) lead of the voltmeter to the B+ output terminal stud on the alternator case (NOT the terminal mounting nut).
If the voltage is higher than 0.6 volt, touch the test lead to the terminal mounting stud nut, and then to the wiring connector. If the voltage is now below 0.6 volt, look for dirty, loose or poor connections at this point. A voltage drop test may be performed at each negative (-) ground connection in this circuit to locate the excessive resistance.
To test the negative (-) ground circuitry, perform the following: Touch the positive (+) lead of the voltmeter directly to the negative battery post.
C'est en fait 2 petite lames qui viennent faire contact avec le levier, j'ai tout nettoye et gratte avec le dos dans couteau et c'est reparti comme neuf.Plus tard RAS au demarrage je roule sans monter dans les tours pour la faire chauffer et au bout de quelques bornes j'ai ouvert un peu plus et elle a cale donc arret sur le bord de la route, point mort un coups de demarreur et la voila reparti et ainsi de suite des que je tirais dedans elle merdait. 1: Locations of the alternator terminals Touch the negative lead of the voltmeter to the alternator case (NOT the terminal mounting nut). Mais j'ai vite compris que c'etait la bequille car une fois ou deux elle calais des que je m'etait la premiere.J'ai donc demonte le cache au dessus du repose pied cote selecteur et la j'ai tripote, moteur en marche avec une vitesse (sur le leve-moto bien entendu), l'espece de contacteur relie par un cable a la bequille se qui m'a permis de conclure qu'il serait plus simple d'oter le cable entre les deux. If the voltage is higher than 0.3 volt, touch the test lead to the alternator case, and then to the engine block. If the voltage is now below 0.3 volt, look for dirty, loose or poor connections at this point.
A voltage drop test may be performed at each connection in this circuit to locate excessive resistance. Be sure to read the operating manual supplied with the test equipment before performing the test. If the Electronic Voltage Regulator (EVR) circuitry is OK, the amperage should drop below 15-20 amps.
With all of the electrical accessories and vehicle lighting off, this could take several minutes of engine operation. Remove the bolt securing the top of the alternator mounting bracket to the engine air intake plenum. 8: Alternator mounting bracket Remove the bolts securing the outside of the alternator mounting bracket to the alternator mounting plate.
Install the bolts to secure the outside of the alternator mounting bracket to the alternator mounting plate. Install the bolt to secure the top of the alternator mounting bracket to the engine air intake plenum. Be sure the drive belt is correctly routed on the engine and correctly seated on all of the pulleys.
