Looking at the schematics, well the PCM controls the pulse width to the injectors , BUT , there is a injector coil fuse , its #2 in your kick panel fuse box , a 20 amp , check it , sure hope that fix ya . that would be sweet .

92 chevy silverado truck will ecm" not let engine fire


If it has an ignition module and fuel injectors than absolutely.

Normally it is either missing spark but has injector pulse, this would typically be a bad ignition module or coil.

If it is missing both spark and injector pulse it is more likely a pickup coil in the distributor.

My 2003 Buick century got hot and quit working now it only turns over and won't start


Can you check cylinder compression? Hope you didn't get it too hot?

Have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, check fuel pressure and injector pulse. Can you check applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.

Lost inj. pulse need to know where the ecm gets crank position from. if from dist.how does it locate #1 1985 crovette


Lost injector pulse. First injector power is supplied by (IGN+) or fues block ,The injector are multi-potr not individual they are fired together,not individually, Now if you lost injection pulse youll need to inspect the Distributor,the pick up is highly suspectable to terminal corrosion, it corrodes easily,so be ready to replace the pick up with a module, (this is spark I know we are on Injector), Do you have spark, then leave this alone, Test injector pulse not at the injector because again its bank fire or group fired You ll need to test thes the connector harness connector,of the injectors.As long as there is spark you should have injector pulse from the injector sub harness connector make your way to the ECM , The ECM controls the energizing of the injector with a transitor or quad driver,they are synchronized to primary ignition . Here a solution if no spark correct for spark. Its either a Distributor pick up failure with ICM module.Do this only is you have no spark.If you have spark and no Injector ,replace ECM

No spark and no injector pulse on a 92 capri 1.6 turbo, dizzy and knock module changed. relays and fuses good, wiring all checks good


When you have both no spark and no injecter pulse its almost always the ignition module. The good thing is you can remove it and bring it to your nearest parts store and most of them will have a tester for those, but I am sure you will find that it is bad.

1992 Buick Century won't start sometimes but has spark in the plugs.


Faulty cam sensor maybe - it controls the injectors. To diagnose, when you get a non-start, spray a V.small squirt of easy-start(ether) and if it runs a little then you have a fuel issue. The spark timing is controlled by the crankshaft sensor so that can be faulty and cause a mistimed spark but usually you'll get a mis-fire in those cases.
