I have a 97 2500 Van with 5.2L.


It just wouldn't start one day. Ran fine the evening before. Not getting spark. Not seeing any voltage at coil while cranking.
Also no fuel pump sound and only 1 click from under hood. No CEL when turning key on.


I have tried a new crank sensor as that was changed a couple years ago. Also primary coil went out a couple months ago and changed that. Changed ASD relay with one from fuse box and nothing different. Cleaned ground by battery.


Cam sensor looks ok from Haynes manual test, but I may try to replace that anyway.


From my reading I guess either the ASD isn't grounding or PCM is shot. Any other ideas before trying new PCM? The lack of CEL and fuel pump sound worries me. makes me think PCM.


Would a bad cam sensor do what I am seeing? Especially no CEL/No fuel pump?


Thanks

With the key on engine off, do you have +12 volts from the coil to ground?

 

No.
No voltage at all to coil.
Swapped some relays for the ASD and still nothing.

Are the large ignition fuses in the under hood fuse box good?

 

Yes they are all good.

 

Test your ignition switch to make sure it is outputting power.

 

The engine turns over. Don't think its the switch. Just no spark or fuel pump.

 

In case anyone else searches,


replaced the computer (PCM), CEL and fuel pump came on and van started right up.

Thanks for the update !

 

Thanks for your update on the problem. Did this repair just involve replacing the PCM and nothing else?
By any chance did you put a code reader on after the PCM change out?
Where did you get your replacement PCM and how much did it cost?

Thanks for your reply. I am having a similar situation.
