2000 jeep wrangler no injector pulse

Check to see if the injectors are getting a pulse to fire, while cranking.

Give some more details of the problem.

have you checked for spark and or injector pulse, you will need to use the spark tester for ignition and a noid lite for the injector pulse

check for spark and fuel pressure and injector pulse

you need to detemine if the problem is fuel (lack of) or ignition. Connect fuel pressure guage to fuel rail and drive and observe fuel prssure when it stalls out. if the fuel pressure stays within spec. then check for lost ign. spark and or injector pulse. If both spark and pulse are missing most likely you need a crank position sensor.

Sounds like the injector pressure valve is stuck open.
This is controlled by the "injector pressure regulator". It opens up whenever the fuel pump pressure reaches spec fuel pressure.
If it is open all the time, then the fuel (via gravity) drains back to the fuel tank; hench, no gas for injectors to draw on.

you need to see if you have spark and check all fuses and see if you have fuel pressure and injector pulse if no spark and no injector pulse suspect crank sensor or ignition control module if no fuel pressure check fuses then relays and then suspect pump

injector pulse occurs regardless of fuel pressure, the pump not working has nothing to do with the opening and closing of the fuel injector, which is referred to as "pulse width" and is measured in milli seconds.

pretty sure the injectors run of the ecu but woudnt swear to it cant u loosen a fuel line and see if pump is working

Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.
