inline4 Posted September 16, 2009 Report Share Posted September 16, 2009 last week (due to a bad temporary wiring job i did, the power to the relays kept cutting in and out) and I had hook up the fuel pump to straight 12v to get it to go up the hill back home. now that I have the car rolled into the garage, it doesnt want to start up anymore. I can still crank, there's spark and the injectors are getting 12volts. any ideas? 92 ish ka car. flame on :o Quote Link to comment
datzenmike Posted September 16, 2009 Report Share Posted September 16, 2009 The injectors may have volts but the ECU is the source of the ground that turns them on. The pulse may be too short to see on a meter. Pull one and try it. Does it spray when cranking. Quote Link to comment
Icehouse Posted September 16, 2009 Report Share Posted September 16, 2009 Check the wiring diagram in the "how to" section and make sure everything is still getting power and ground where it should. Then go from there. Spark, fuel and compression. Make sure you have all 3 :D Quote Link to comment

Make sure you have all 3 :D i did end up shortening the injector wires, but it was working fine for a few weeks before that, but like you said and dan said, it might be the ground not grounding anymore...
