Hello, thank you for your time.....the truck ran fine and sat for three days...she will crank and not start. Now, the odometer has dashes with no numbers on it, the theft light blinks/flashes while trying to start it. I noticed the fuel pump relay did not make any noise, nor did the pump, so I jumped the pump in the fuse box, and the pump works fine. I am assuming it has something to do with the PATs system, or the PCM....I did use both keys and that made no difference to the theft light. Is there a way to by-pass that, and if so will the odometer come back...I have studied the schematics for the wiring, and I do know that there is a PATs system by-pass available for purchase, but I am sceptical that it will do the trick.....can anyone help guide me into the right direction with out the use of the dealer???? Thank you for reading my post.....I am a firm believer for paying for services rendered if they are of value. So, please be honest and so will I...thank you

Three things needed to make it work are Pats system, including the keys, and module, Instrument cluster, and PCM, To check your cluster pull it of and measure the resistance of the LED, in both directions, Resistance should be greater than 10k/ohms in one direction, and 10-20 ohms with the leads reversed, if not replace the LED, if ok replace the clusrer. The best thing to do is to retrieve the B codes stored in the PCM...this will point you to the faulty area...
