You need to check with a test light now, and see if you have voltage at any of the two wire's going to the injector, if you do have voltage, reverse test light at battery and check other wire, that will be ground pulsation, if you have voltage and no ground, ground is control by the computer, computer will need to be replaced.

Where is the gas regulator located on a 1996 jeep cherokee (2wd) ? Why is my jeep turning off and want start, until it sits for awhile; I have change the fuel filter and fuel pump?


You meant the fuel pressure regulator? It is located on the fuel rail and has vacuum attached to it. This is not the problem with your car tho. Check the ignition module, and the ignition coil.

1999 Jeep Grand Cherokee Larado wont start. Cranks, but injectors do not pulse( fuel rail has pressure.)


If computer sees no crank sensor signal it shuts down pulses to the injectors. But, you bring something new into the mix. Make sure fender grounding is good so the relay can operate properly and make sure power going to it is not restricted by a loose or dirty contact on the power side.

I believe you are on the right track. E.C.U. or relay.

Jeep grand cherokee 95 fuel pump takes long time to start ,


First install a fuel pressure tester on the fuel rail and check the pressure during crank. It should be about 30 psi.If the pressure is not good then it could be a bad fuel pump relay or fuel pump itself (in the tank).
If the fuel pump pressure is good then you could have a bad crank sensor.
