(Solved) No power at fuel injectors
I have a 2001 Cherokee 4.0. Was driving fine yesterday, always ran a little rough when first started, but always started. Yesterday night I go to start it but ran a little rough so I turned it off to restart the engine. If it was running rough in the past I would turn it off and restart it and it would run smoother however last night when I went to restart it it didn’t start. I left it sit over night and went back today and it started ok. Drove it to my shop and parked it where I replaced the crank sensor and coil for shits and farts and went to try and start it and I didn’t get it to start. It turns over fine but doesn’t run. I verified spark and it ran for a split second with gas down throttle body (didn’t have anything else such as starting fluid). I checked for fuel at the Schroeder valve and some gas came out but wasn’t very pressurized need a fuel pressure tester. However when I went to check the power at the injectors j read that the hot side should have 12 volts present with key in the on position. When I check my injector harness I only had .1 volt present. All fuses in engine bay panel were fine.
I went to check the interior fuse box on pssenger floorboard and the only fuses that showed hot with a test light were the 3 yellow fuses (I believe 25’s) at the top of the panel, all of the other mini fuses showed nothing, is this normal?
