    then the spark must be at the wrong time or it would run, of that is unless u are trying to start it with the air cleaner blocked off.

You need to check the basics of combustion; Is there spark at the plug wires? Do the fuel injectors receive the pulse to fire, from the ecu? Does the fuel pump turn on for a second, when the ignition is initially turned on? All of these problems I have mentioned are related to the ecu being faulty.

you are saying it is getting spark, and fuel, right? If it is getting spark, and fuel in to the throttle body, check compression-make sure the Mass Air Flow sensor is plugged in, and double check your spark-you say you replaced all those ignition items, but do not say that you have spark.

My 1991 jeep wrangler will not start. Engine turns over fine. The engine is getting fuel and has fire to the spark plugs. I have already changed the distributor (cap and pop up coil), plugs, plug wires,...


Check the timing to ensure it is correct.
Check each cylinder for the proper compression.
Try starting the jeep with some starting fluid. If it starts with the starting fluid, you may have a few bad injectors, or faulty injector wiring harness.

1991 4.3L GMC Jimmy S-15 will not start. Turns over, but does not start. Replace spark plugs and wires, ignition coil, module checked good. The plugs are gettin fire but not sending it to the motor?


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.

Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.

You need to find out if you have spark there, if injector is working and if the cylinder itself has good compression. Then, you can work backwards to find out why whatever is "missing" isn't there.

No injector pulse, no current to the injector


Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.
