97 k1500 5.7 vortec no fuel at injectors please helpi bought the truck with a blown motor to fix up i put a new motor in it and why i was doing that i pulled all there security system out. when i try to start the engine it has good fuel pressure at the check valeve but its like the injectors are turned off cranked for 30 minutes and the plugs were dry and had no smell of fuel.the power source that goes to the injectors only has power on every other terminal when the key is on
That sounds about right as the injectors are negative triggered from the ECM, you are going to have to find where the alarm was tapped into so it could interrupt the signal from the ECM to the injectors.
thanks tennisshoes would replacing the ecm work i threw all that alarm stuff away
I wouldn't head there yet, you need to check the wiring to and from the ECM, it will onLy take. 1 wire to shut it down. Do you have a shop manual with a good wiring schematic? If not buy a good one like a Motors or Mitchell or you could go to your local library and get a photocopy from their reference manuals. This will take some time so don't get frustrated.
