Question about Cars & Trucks
Car has new plugs new wires new dist cap rotor button ignition control module and even bought a new computer car ran great then injectors stopped working previous owner had the injector harness wired wrong had blue wire going to green and fried the connectors so I changed it car started injectors pulsed then nothing now they won't fire any suggestions will help gets fuel has a aftermarket electronic fuel pump anything will help everything's new
If you have spark, the computer is getting the signal to pulse the injectors.
If you have power but no ground pulse, you may have fried the driver in the computer again.
You could get a used computer from a junk yard to test it.
There could be a short in one of the injectors or the harness at the computer, or a break in the circuit from the computer, and that could kill the driver in the computer.
