1994 6.5 turbo diesel not starting, this truck has been a pain for a while now it was shuting down while driving so I replaced pmd the problem remained and slowy got worse now it dos't run,there is no fuel at injectors ,replaced transfer pump and injection pump,tried more than one pmd,replaced pcm as per gm book, tried different eprom, checked ground wire on back of block, the problem i have found with no solution is the signal to the pmd fades out after 2 or 3 pulses I checked it at the pcm exactly the same.

Were is the signal to the pcm supposed to come from?

 

Sorry i posted this in the wrong section

And Hi I'm new !

 

Check the CPS and OS.

also verify the LP operation when the engine is running-OPS powers the LP at that time.
Google OPS relay mod and install-AC Delco ONLY for OPS and CPS and all electric parts for these.
