I have a fuel injection issue. I bought the car not running. It has djet (?) Fuel Injection. It hasn't run for about five years, though they said it was running when it went in the garage.
It does start and run, but strangely it seems to run after I unplug the fuel pump relay. The fuel pump relay is mickey moused. Meaning it has a hot wire coming from the coil and wrapped around one of the relay posts and then plugged in. Without that wire the fuel pump does not turn on. With the fuel pump running the car does not want to start. After unplugging the fuel pump relay it starts good and runs good for a few seconds. I know little about fuel injection but am willing to learn. I really want this to work for me. I have a multi-meter. What should I check first? |

Excellent. Yes, the CHT regulates how rich the mixture is during warmup, and with it disconnected, the ECU thinks the engine is very, very cold. So, the mixture is set very rich, and the engine will die as soon as it warms enough. Cylinder head temps rise pretty quickly (like 30 seconds of idling to get to normal temps from dead cold), so the engine won't run long.
Sounds like you have a fair amount of rewiring work to do. |
