Besides the battery and aultanatior what would be the reson for not starting?


Alternator is not even in the starting circuit

No Crank or NoStart ---- they are different

You tested for a dead battery

If you need to jump a vehicle,don't

Find a problem-- anything & resolve it

You can ruin the electronics, jump starting or
some day you eventually will,luck only holds
out so long & you learn the hard way

Do you have spark & injector pulse while cranking

Do you have fuel pressure at the motor key on or cranking

Why no vehicle,year,motor-- shown here?

Details leading up to this,always a story that is a secret

No injector pulse


1991 this make you OBD1 . You can access a code by jumping 2 terminals together.The injector pulse is from the PCM . If you have no pulse you need to troubleshoot for spark first . If you dont have spark do spark first then injector pulse comes on. If no injector pulse check fuse in engine junction box.Use a volt meter check grounds at PCM. If all else checks out good replace PCM. You may also want to check the TPS. If this sensor short out in the WOT position you also wont get injector pulse.SO disconnect the TPS. and recheck for injector pulse

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 gas coming out the injector and there is gas pressure to the injector?


Is there an injector pulse going to the injector?(an electrical pulse to fire the injector).
Is there spark at the plugs?
If the pickup in the dist is faulty you won't have either one.
If your vehicle uses a crank pickup with or instead of dist pick up....if it is defective ....no pulse.
The above is 90% cause of no pulse....other is computer problem 10%.
If you do have a injector pulse and no spray.....and have fuel pressure....change the injector.
A quick check for spark is spray a little starting fluid in it.....if it starts on the fluid....spark is present.
