Jeep won't start, no fuel pressure, help!
- New fuel pump
- New plugs and wires
- New distributor cap
- New coil
- No fuel pressure
- No power to the pump
- Fuel gauge not working
- Fuses checked and replaced
- Battery is good, cranks but won't fire
- No spark from coil to distributor cap
We know this is a fuel problem and the engine is not getting any fuel, completely lost on the fact that the pump has no power (probed the plug while replacing the pump) and don't know where to go from there because the battery is working fine. Turning the key to the on position doesn't start the pump at all. Any ideas on what to check? Also, last month it took longer to start than normal, that's why we replaced all we did thinking it was the problem. Is there an emergency killswitch possibly? Fuel pressure regulator bad maybe?
Thanks

Its your Crank Shaft Position Sensor that goes through the bellhousing of trans on driver side. You can follow the wire for it that goes to pass side against firewall. Little hard to get to. Mine went out recently too and it wouldnt turn the fuel pump on wouldnt get spark and the gauges wouldnt come on and obd2 connection didnt work. Sorry to see all the parts you replaced on trying to fix this problem.. good luck P.S. welcome to the forum too! hope you stay after you fix your problem very helpful site
