Hello all, well my o3 is down again. wife was driving it died at a stop sign,wont start. changed the fuel filter, no help, the repair shop says he cant comunicate with the pcm. Does this sound like anything you've come across? Between 400 and 500 $ for the pcm then who knows ?? from there.
he did say theres fuel in the filter cup.maybe some one can help with the trouble shooting thats been thru this. Thanks

 

Any codes? Key on/off 3 times and read out on odometer. Does it crank and just not start?

 

the garage i took it too put a reader on it. Said he could talk with abs mod. but not the pcm.it does crank but does not catch or try to start. I'll tell him about the code read trick. Thanks

 

Check the wiring harness from the AC compressor where it runs up and around the engine to the firewall. If it frays it starts grounding and pulls the voltage down and the PCM will not communicate and the injectors will not trip.

 

Good point! I forgot about that.

 

Well had to take it to a dealer,After playing with it for 4 hrs. found the rad. fan was bad. I just had one put on march 07, plus the lift pump is bad and after they fix all that they'll be able to tell me if the injector pump is bad.Its up to 1300$ already without injector pump. I cant tell you how PO'D i iam. Over 40,000 $ with my emp. discount I paid for this truck,plus the 2500 i just put in the front hubs,and had the transfer case rebuilt 2 weeks ago,that was 1000$.It has 130,000 miles on it. I should not have too even worry about these kind of repairs at that milage. maybe time to to a Ford or Chevy. i still dont feel better after all that! Venting LOL.Is there a better after market lift ? of fan out there?...thanks for reading and help

 

Remember, you're going to have issues with any truck, some are good and some are really bad. Must have been built at 4:59PM on a Friday!! Sorry to hear about your problems. What I don't understand is what the hell took them 4 hours to tell you the radiator fan is bad...and what does that have to do with not starting? Also, why was the job for the front hubs $2500? Sounds to me like you need a new dealership! Sorry to hear about your troubles, it's no fun no matter what truck it is! Good luck.

 

IF the lift pump was still the original on the fuel filter canister I'm surprised it lasted as long as it did. Good news is that the Cp3 doesn't seem to be bothered by the loss of the lift pump so you should be fine in that area.
