okay, so I know that L-jet uses the point pulses to fire injectors...my main relay is working, so what connections do i need at the coil?
i already have the tach wire, the point wire at the neg and nothing at the positive.... but i have a brown wire and two black wires joined to one both sets of wires having 12VDC on them....what gives? b |

dont make it so complicated in your mind.
to make it fire and start you need gas, air and spark. You have spark. you need fuel. You can run the pump all the time , and it will last for a bit, but eventually it will burn out. So for this test, jumper it so it is running and make sure you have fuel at the injectors, at the right time... I take out both injectors from one side, put them in baby food glass jars, run the pump and turn the motor over... You should get fuel in each jar...if not they are not getting the signal to fire... it is an electrical signal of something like 3volts. Again a test light will work here also. If you find one is getting fuel and the other is not, switch them to make sure the injector is not clogged. Make sure you have pressure at the injector as well. Dont be looking for relays just yet. As I recall they control the fuel injectors, so you need to determine which one is bad, if any. Rich Rich |
