Bradford Posted August 15, 2018 Share Posted August 15, 2018 Driving the other day was running fine, went over a rough bridge and it shut off. No codes are flashing. When I have my key power off by brake air light stays on on the dash now. I've checked the frame ground, the ground behind the speedometer, replaced my engine position sensor and speed sensor, oil pressure sensor, and my ECM and also cleaned my coolant level sensor. Started for me this morning and ran fine for 5 seconds and shut off. Running out of ideas Quote Link to comment https://www.bigmacktrucks.com/topic/54043-98-e7-etech-runs-then-shuts-off-then-wont-run/ Share on other sites More sharing options...

Mackpro Posted August 15, 2018 Share Posted August 15, 2018 If this is a non-ETECH engine, check the big solinoid in the fuse box.

Jeremy_Brault Posted August 19, 2018 Share Posted August 19, 2018 Grab the wire harness by the air compressor and wiggle and try it. They break where it turns and goes behind the engine.
