This issue popped up a few weeks and i had created another thread on it, but just as a re-cap.
My truck will run and run all day long without a single issue or hiccup. But 4 times now its had an issue where it will not restart. It will crank and crank and crank, but won't even try fire. No codes, tach reads good, ICP and DC look good, and i originally thought it was a fuel issue so i built a fuel system. I've swapped CPS's, IDM's, cleaned every connection, and ohmed out a lot of wires that checked out perfect. Even after all this stuff, it was acting the same. Finally I unhooked the ground cables on the batteries and let it sit for a while. Came out, hooked em back up, and the damn thing fired up like nothing ever happened!
A week later it did the same thing at the farm. And again, unhooked the batteries for a little bit, and it was good to go.
2 weeks go by, yesterday at the dirt drags i put 100 miles on it getting there, made 4 passes, and a good amount of idling without a single issue. Then it hit again, right before the start of the semi-finals. Cranked and cranked and wouldn't start. This time it had a CPS code, so i tried tracking one down with no luck. By then it was too late to run so i had to drop. Halfway through that class i decided to unhook the battery cables and let it sit. Little bit later i hooked em back up and it fired right up and ran great like always.
Then this morning on my way to work i stopped to get some breakfast, and again no start. Unhooked the battery cables for a minute, and it was good to go, and has been fine since.
So is this a sign of a failing PCM?
