I have a 95 blazer 4.3 vortec, cmfi, edI. My fuel pressure is 60psi and I have spark (I used a test light pooked into the rubber spark plug boot) I went to test my fuel injectors by testing for power and the pulses using a test light(I dissconnected the wirering harness that go's to the injecters) I got a steady light on one wire and nothing on the other. So I was unplugging other sensors to see if I could get a pulse and then I got no power at all going though the one wire so I plugged every thing in and it started right up and ran great for 5 min. Then just shut off, I checked my wire and it had power I tryed starting it a few times and my power went off in the wire agine so I plugged it in and it started right up and died after 3 or 4 seconds I can repeat this over and over aging. Im confussed now. Oh my problem was it felt like it was running out of fuel so I pulled over and it died so I towed it home and started checking thing out.
