97 truck is dead again
A few months ago, I replaced the IDM, and the truck had been running perfectly. Last week I replaced both batteries because they were getting old and slow to crank and finally just wouldnít crank. I drove just one day after replacing them and it ran perfect. Parked it on level ground and the next morning, dead.
I immediately suspected the IDM because it is not fuel, as there is 25 psi like always at the bowl (I replaced the Schrader valve with a fuel gauge). Had another IDM sent to me, replaced it and much to my surprise itís still dead, with not even a hint of firing.
Iíve done the usual: checked all fuses, unplugged ICP, tach reads about 200 while cranking, has a new Ford CPS, WTS comes on and goes off as usual, itís still dead. Only thing I havenít done is checked oil at HPOP, because the Allen head bolt stripped for the right size wrench, so Iím going to try tapping a Torx male socket and see if it comes out, and replace it with new one. I doubt that ití is that, because oil has always been full, and with all the cranking I have done, it wouldíve filled back up, and this happened after a full day of driving, and last week, it sat for over a week, and after I replaced the batteries, it started in les than 3 seconds of cranking, like it always does.
Iím going to try swapping around the IDM relay, but I canít remember which one it is, because it still sounds electric to me. I know there is fuel in the bowl and fuel pressure, and mechanical problems donít show up like that, from 100 to 0 in one day.
The truck is 100% stock and other than these episodes, always reliable.
What else am I missing. Any help will be appreciated.
