So could a bad ignition switch have been the reason they straight wired the starter.

 

The relay i have pictured is almost $90 from autozone, but the fuel shutoff relay listed on geno's garage is only $20. Whats the difference between the two and why is genos so cheap? The part number from the one from autozone 19384.

 

Could, or it could simply be a broken wire not feeding the 12V to bring the relay in. You have to start probing for voltage.

As for the relay, AutoZone is not your friend, Rock Auto has Standard RY607 relays for fuel shutoff for $14.48 each, they also have Airtex 1R1153 relays ( the same one...) for $ 96.89.

It pays to shop around man..........

 

Yeah it does.

 

Any updates?

 

I finally got my fsm in and the new fuel shutoff relay in. The truck now will start without the bridged connector and will start using the ignition. Now i just need to track down why the pcm and tach arent working, any pointers where to begin?

Also in speaking more with my cousin about the truck he said that he had the pcm replaced, might it be possible he got one from another year thats why its not working? and also whats the model number for a 97 auto pcm i dint see one in the fsm.

 

With the damaged wiring, and the wiring hacks, have you checked all the fuses under dash and under hood. Im sure you have but I wouldnt be suprised if it maybe popped a fuse.

 

Yeah ,i check them all but im going to reolace all the ones under the dash just to be sure.

 

From the parts manual, the following are PCM numbers, might be updated part numbers, if you suspect you can put to old P/N in at places like moparpartsamerica and they give you the latest revision. Doubt you would need to on an item like a PCM though.

Federal Emissions, Automatic, 56040454AA
Cali. Emissions, before 1/1/97 56040454AA
Cali. Emissions, after 1/1/97 56040506AD

As for the Tach, nothing I can say other than start tracing wiring, it is a PITA, but necessary..........

 

Thanks, for the part numbers the weather just cleared up here so im going to start working on it again tomorrow. I hate auto wiring!

 

Are there any guys in Houston that know these trucks well that wouldnt mind giving me a hand, i'm starting to run short on time?

 

the part number on my pcm was 56040504AA
This is supposed to be a new pcm

 

Can't find it in my book, but here is what moparpartsamerica says it is, shows correct for a 97.

List Price Core Price Your Price

Electrical - Ignition system - Eec module Eec module - 5.9 liter, diesel 1997
$590.00 $0.00 $393.33
Part number 56040504AA was superceded by part number 5012993AA.

 

From the parts list it looks like I am missing the mounting bracket, is there a way to test the pcm?

 

No way that I am aware of.
Any chance that you can find a DRB3 to borrow? ( Chrysler scan tool ) Not sure if others you can force 2 way communications......

Anyway, a bad PCM would be a rarity, since 1995 they have the bus voltage protected, took most of the fried PCM problems with it.

Something else I just thought about, are you sure they flashed the PCM?
