95 Grand Cherokee wont start
Hello everybody, new guy here. Hope to be here for a while.
Got a 95 Grand Cherokee Limited 4x4, 4.0, Automatic, 175,000 miles. Car ran good and always started up. I was on the highway one afternoon and the car just quit running. Got it home and figured out that I had no spark or fuel pressure. Fuel Pump Relay and ASD relay were clicking very rapidly. Turns out, the oxygen sensor harness melted together on the exhaust manifold. I repaired the harness, and the rapidly clicking relays stopped. The fuel pump began working normally, but it still will not start. Pulled codes, and im getting codes 12,33,23,24. Mostly sensor codes, but I dont beleive they are sensors that will cause it not to start. When I turn the key forward, I get power to the injectors and coils for about a second, but when I try to start, they dont receive any power.
I figured the wiring harness burned up the ECM, so I bought a good used one (Heard the car run), with identical years and part numbers (56028026), but nothing else changed.
Even took the ECM harness out of the car and checked for any melted together wires, and didn't see anything. Swapped good relays for the ASD and Fuel Pump, didnt work.
Im out of ideas, maybe Crank Sensor. I hear its common.
Thanks again everybody.
