Electrical problem
1988 Isuzu Trooper 4 cyl Four Wheel Drive Automatic 165000 miles

My fuel pump will not run unless I puill the engine relay. Even with engine relay pulled and fuel pump running the engine will not start. Did not check pressure but when I crack the line it sprays.
Will start on starting fluid.
Thanks

Check fuel pressure if its within specs and also for injection pulses.

Did your replace the fuel pump relay. These are interchangeable with the engine relay. I had a short under the relay and had to replace the wire.
Also the fuel pressure regulator at the end of the injector tube could use replacing just in front of the intake.
