I recently experienced hard starting with my '99 Ford 7.3 F-350 CC LB SRW 4x4. Then it turned into a no-starting issue. I managed to determine the culprit after systematically troubleshooting, and replaced the ICP sensor with a replacement kit from NAPA. However, I now have a engine check light and my Auto Ingenuity scan tool is reading a fault with the sensor, it will not perform a engine parameter scan while running. I made sure to methodically swap out the wires individually when replacing the original pigtail wire connector, as it was coated in oil. Should I disconnect the batteries to reset computer? I would greatly appreciate any feedback.
No Dice! Went to the dealership and forked over double the cost of the NAPA ICP senor which I had just bought, and replaced it with the OEM sensor to the same result. The service engine light, triggered by the ICP sensor according to my scanner, is still on. I'm not sure if any internal damage could result by driving it in its current condition, so my truck will continue to stay parked until this is resolved. Has anyone else encountered this scenario?
The ICP (pressure) is controlled by the IPR (regulator) solenoid. Confirm the small tin nut is still on the IPR. Inspect its wiring. I’d also double check the ICP wiring, especially since you just changed the pigtail.
An ICP issue shouldn't cause a no start, the engine will run just fine without it. Not as efficiently as if the PCM had that data, but run she will. What code is reporting? I'm w/ Jason on double checking the wiring connections. If they're plain ol' crimp butt connector then for sure triple check, I've been bit more times than I can remember by those little guys. It's why I switched to using the non insulated ones so I can crimp, then solder, then heat shrink, double layer if possible.
