My 94 Dodge Ram B250 won't start. Engine cranks, no fire to distributor, apparently no fuel either. Any suggestions?

 

Maybe a bad ASD relay issue, possibly a bad ECM/PCM (computer).

Getting a Check Engine light?

 

NO ck eng light, but no ck eng light when you first turn on ignition. Idid ck 4 relays, 12v at pins 30 and 86 but one relay also hat 12v on pin 85. Bad ground I'll pull that relay today and temp jump 30-87 to see if that helps.

 

I jumped the relays and got 12v to ign coil, fuel pump came on and power to injectors. Still no fire from distributor. The only fuse panel I've found is in glove box.
Any suggestions, all help would be appreciated.

 

bad distributor, high tension wire to coil pack, or the coil pack itself?
possibly Crank Position Sensor (CPS) but unlikely since you're getting power at the fuel pump, etc.

I 2nd the ECM----'bout $60 from autozone

 

If he's getting power by jumping the ASD relay, wouldn't that kind of rule out the ECM/PCM? I suppose it could be intermittantly faulty/finicky.

I'd troubleshoot all ignition-related components downstream of the ASD relay. As alloro here on the forums has pointed out countless times, components like the high tension leads can provide inconsisent performance.

 

Thanks for all the good info about trouble shooting coil, crank position sensor I'll run those test this weekend or fist of next week and give ya'll a report.
