Thread: Auto sparkies

Got one here that's a bit out of my league. Its an old jeep wrangler winch challenge truck that's had a efi six put in it out of a Cherokee, and what a rough job. It doesn't go no injector pulse and no spark, easy I thought crank angle sensors always give problems on these. Tried a known good sensor still no go so had a bit of a look at a wiring diagram and did a bit of reading, the sensor is a 3 wire and the earth apparently is pulsed on and off by the ecu. Anyone actually know if I cut the earth wire that goes to the ecu and just earth the sensor will It fry anything?
