Hi Guys!
Please bear with me as I am posting for a friend of mine who currently works a ton of hours and is having problems with his truck - fixes it himself.

Last Sunday he started truck - backed out of driveway and once in street - heard a tick noise and truck died. After doing a number of things so far such as, replacing the fuel pump, replacing the fuel pump relay, new fuel filter, oil pressure switch and has replaced the ECM/IGN fuse several times - when he replaces - truck will run - but fuse keeps blowing out. He's replacing the ignition module today. He has talked to various mechanics in the small town he lives in, but nobody seems to have a clue. So, I found this forum and thought perhaps I'd throw up a post in the hopes that some of the knowledgeable people here might have some idea as to what might be the issue. We would be very grateful for any assistance.

I'll be giving him the link to this forum so he can register. He loves this truck and is intent on restoring it back to new..I am sure that when he discovers this forum - he will join up - but as of right now he's working..and when not working trying to get his truck back on the road - it's his daily transpo.

Thanks so much in advance for any help!

He needs to find out exactly what is protected by that fuse. I would say the more likely problem would be a problem with the wiring harness rubbing on some metal corner or other sharp surface, causing a the fuse to blow. Tell him to run his hand over all the wiring harness on and around the engine and check for any signs of wearing or scuffing. It doesn't even have to have the wire visible within the insulation. It's a hassle, but try starting it and then grab and shake all the wiring harnesses to see which one causes it to fail.
Good Luck and God Bless
