hello, we can not rule out a pump leaking back, not working during crank, etc but do understand you hear it. Since there is not a fuel pressure test port, testing pressure requires special tool.. We now to to check some other basics.
I need to know if you have a 12 volt testlight. If not, can you get one. this is important
I need you to pull off the plugs to both injectors. Do the test when you know vehicle will NOT start.
Using your testlight, turn key just to ON/RUN. Probe both injector plugs. The wires with same color going to BOTH injectors should be hot all the time.
Then,,,,, I need you to reverse your testllight meaning.. the probe end on battery POS and the clip end to one of the OTHER wires going to injectors, crank engine. I need to know if the testlight blinks.
All of the must be done under no start. We need to start there and then move on. LMK Thanks
We are not permitted to call nor can I view your number ther is a power feed problem somewhere, It should run on gas in t body even if no poer to injectors. This now tells me you have lost spark as well. I have to think where to go next.
One thing I need to to check is see if you have 12 volts tto both side of the INJ A/B fuse in fuse box.with key on
Sorry , you said since wires mot hot, would not continue to run. I took that as it was not running at all with gas put in.
Please check the power to fuse i noted. We have to find out why the red/white are not hot
There is a timing connector under the hood shown below. Single wire that you unplug to set timing. I need you to locate it , unplug and the see if it will stay running
