OK heres what happened im driving down the road and all of a sudden i heard a pop like a fuse blowwing well then the engine just dies all gauge lights and everything else worked just engine dies.I pop the hood and the boost soleniod plug that I dont use because i have a manual b/c was melted to the turbo which in turn blew the ecm fuse for some reason so i get all that squared away and try to start it it wont start.I dont hear the fuel pump priming when you turn the key.I jumped the fuel pump out and it comes on.Any help would be appreciated>

Re: Help PLEASE

Mine did the exact same thing about a year ago. Did you check both fuses?? I changed the fuse(s) and it took care of the problem.

Re: Help PLEASE

Time for a new ecm? Are you getting spark? I worry damage was done to the ecm when the wastegate solenoid connector melted and shorted out on the turbo. Did you check all the fuses? Do you have any type of scanner to check communication with ecm? Sounds like you have work to do!

How/where did you jump the fuel pump? Did your engine turn over and start when you jumped the fuel pump? Did you test all fuses, not just look at them. Sometimes fuses will "look" good, but have actually blown. Did you test the fuel pump relay? I have about a dozen more questions to ask, but that will get you started on trouble shooting.

Re: Help PLEASE

Oh yeah and i had to be pulled home 5 miles with a chain so most of my trouble shooting was on the side of the road while i was extremelly pissed and scared because i have no tag or insurance on the truck yet.I had thrown the tag from my daily driver on it.

Re: Help PLEASE

I'm thinking that the wires that run to the OEM boost controller are NOT on a fuseable link... That being said the ECM fuses regulate the power to the ECM. Very possible that the wires shorting may have shorted out something in the ECM thus causing the fuse to pop... My vote would be on testing out the ECM... Know anyone in the area who has a truck?

Re: Help PLEASE

x2 on the CEL. x2 on checking fuses with a test light or meter. Looking at fuses doesn't say anything out the rest of the circuit.

The fuel pump is controlled by the PCM through the FP relay. The only input it needs is the ignition turned on. Otherwise powers and grounds for the PCM. The Dark Green/White wire to the relay should have power for a few seconds when you turn the key to run. If it doesn't see last paragraph.

You can even turn on the vehicle and see if the PCM is alive enough to supply a 5V ref to MAP or TPS. No 5V? See last paragraph.

Power should be available on A6, B1 and C16 at the PCM. Grounds D1 and A12, B5 and B6 to have the FP run on initial key-on. I vote fuse or PCM. PM me if you want me to email you a wiring diagram, connector diagram and a circuit description for each.

X2 :tup: If that's all fubar... your looking at approx $75 bucks for a new ECM. Hopefully the MEMCAL is alright if not you can score one of those too... Good luck!
