Check for a signal at the ignition coil with a node light or a 12 volt led test light while cranking. Check for a signal at a fuel injector connector jack while cranking. If both these signals are missing. Ignition and fuel signals, then the problem may be some common point. My 've will loose both these signals if there is no crank shaft signal or position sensor. CPS is on rear of engine, on transmission bell housing. Check for connections of PCS.
Pretty sure the regulator on those is in the computer (I know...really dumb...) There is a way to wire around it using an older style regulator but it will keep the check engine light on and may not pass inspection like that.
Remove the harness plug and check each pin for corrosion and connection to the wire behind it. The problem is a wire or wire connection, but I can't tell you which one but likely its a ground or power lead as sensors would usually not shut it off but would give you a component failure code and check engine light.
You need to begin tracing harness wire that has no power, back to the computer. If you can locate the wire at the computer, first check it there. If no signal from the computer at the pin, then change computer.
There are broken wires in the wiring harness between the frame and your driver's side door. These wires control all the windows and door locks in a 95 Jeep. Same thing happened to me. You will have to cut the rubber boot to get it off and check which wires are broken and repair them.
Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)
had same problem with 94. in the door jam there is a rubber boot that holds all the wires for your power windows and locks and stuff. remove the boot and check each of the wires in that harness to make sure they are not broke. that's what was wrong with mine on both doors. the wires break with repeated door openings.
where is the egr valve on a 95 jeep grand cherokee laredo? I have chnged the spark plugs, wires, solanoid and all are functioning properly? Any suggestions? The plugs are nt chorting out either. Thank you for your time.
