Well here is a company I found that sells the ECM module to match the VIN. They will also refurbish your ECM and return it (250.00 or so for a refurbished ECM with a warranty). Refer to the link:

I'll let everyone know how it works out. If this doesn't work I think I'll give up since I have trouble shot every possibility.

 

Auto computer exchange has a REALLY poor reputation. Folks have gone thru several PCM's from them before they actually got one that worked.

 

Thanks for the heads up on Auto Computer Exchange. Has anyone delt with All Computer Resources? They are based in Miami - makes me suspicious they are the same group as Auto Computer Exchange.

 

I don't think I have seen anyone talk about a PCM replacement company that they actually LIKE..... Check business addresses on those two though, and see if anything looks fishy.

 

I would also try a cap and rotor and check routing of wires.... I am actually doing that myself because of misfire codes I get randomly while the engine is cold...

 

Well I replaced the PCM and no luck. I have replaced every sensor in the f'n beast as well as the computer and thoroughly checked the wiring harness. The truck is being sold as is. For those of you that think you have a solution that has not been discussed here let me know quick. Thanks to those that have tried to help as it was appreciated.

 

Well it seems like I had a number of problems all occuring simultaneously. While it did not appear the computer was the problem (PCM) it may have actually been part of the issue (by the way the contacts on the male connector portion onf the PCM corrode causing intermittent contact with the wiring harness and thus problems can arise).

This morning with with a nice balmy temperature of 4 F I finally got an error code. The new PCM has been installed for 3 days and I drove the truck for about 1.5 hours since. The error code is P0135. ZMAN17 you can say I told you so if you like as it is bank 1 sensor 1 O2 sensor.

So now the following has been completed:
- new intake manifold gasket
- new TPS
- new crank shaft sensor
- new cap / rotor / plugs and wires (yes the routing of the wires was checked to avoid induction)
- new MAP sensor
- new PCM
- wiring harness checked (factory splice that supplies power to the PCM)

Total cost to date for all this work is approximately $1740.00. I did not have time to do the intake gasket on my own, however I completed all the sensor changes. The PCM has a security module and had to be done by the dealer (1.6 hour shop time - yeah right, but they had me by the ***** . . . . . I could have ripped it out, installed the new one and programmed it in 40 minutes or less including the time it takes to get the tools and set up). The PCM new from the dealer was $650.00 + tax and they had to program it (flash it) in the shop.

So this leaves me with the O2 sensor which should cost me about $80 and I can do it myself. I hope this works. At least all of this is still cheaper than a new truck.

I really hope this post is helping a few others with their problem - even if I did not start it.

 

I hope its not the o2. Especially when ppl three or four pages ago were saying to change it. Good luck

 

The o2 is the first thing to go bad after the gasket blows.(and I would never say I told you so) Did you just have the lower intake gasket replaced, or did you have the plate replaced also? With a Hughes or similar.

 

I had the gasket and plate replaced - I had a friend that has a local shop do that for me though (short on time). Out of curiosity, how does the spark advance get screwed up from a shot O2 sensor - or was/is that a separate problem?
