Conversation Between joe_r_dog and Rusty Axlerod

Small but important correction joe. It's possible to unplug the IPR sensor and truck starts and it be an oil leak, but not likely. If actual IPR was at 485psi for example. Unplugging it would tell the ECM the IPR was 500psi and truck may start if temps were just right. It's more likely if you unplug IPR and truck starts the IPR is bad. With ScanGauge it's much easier. Just bring up IPR Xgauge and IPR must be 500 to start.
