97 No Crank, No OBDII No start,
Alright guys, HEre is the full story pipe in and ask, ill answer any questions, and try/test anything.
I have a 97 7.3 PSD 4spd auto,4x4, extended cab. In January I drove the truck to work, slipped and fell, was takin to the hospital and left my truck at work, My wife went to pick up the truck while i was home recovering, and the damn truck wouldnt start. I showed up a week later and attemted to start the truck no luck. gave it 3-4 days and tried again, after checking for fuel in the bowl, and trying to hook in with my 300 cheap scanner. Truck started and ran home, parked it and then it would start again.. Cheap scanner had no connection. Fuel bowl was full. After not being able to hook in with my cheap scanner I talked to Snap-on and picked up a Solus Ultra 3400 dollars later i hooked into my OBD2 port and magically my truck started and ran. 24 hours later, no start, no connection. truck hasnt run since this was near the end of February. Batteries are tested at 900 cca@ 12.6 vdc, grounds test less then .02 ohms to battery terminal. positive tests at .02 ohms to battery + tested at ECM unbolted from ECM under driver side hood connection. Solus says ecm does not excist, OBD terminals show .01 ohms tested from under dash to under hood @ pcm plug. Fuel bowl is full, mechanical lift pump is working. last time i was able to see pump pressures were at perfect levels. Had a suggestion from another ford tech to check IPR connector for circuit ground, checked based on his suggestion, found connector insulation in plug had melted, repaired insulation. New ecm ordered on warranty. I replaced the ECM a week after a bought the truck, it was sending bad signal to the IDM. New ecm installed, with identical results, third ECM ordered for good measure with identical results.
As you can tell i do have a bit of experience, When we find a solution ill be more open about my credentials.
I am open to any tests, ideas, suggestions, questions.
Thanks for time
