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? |

I found the hand grenade thingy with a hose and four wires so I do have the djet for sure.
I am checking the flow charts now. It does crank fine. With and without the fuel pump running. The wire that is jerry rigged is a hot wire from the positive side of the coil running right to the bottom end of the relay. Wrapped on a post of the relay. I disconnected it from the coil and went straight to the positive side of the battery post. I confirmed it would start and run well (for a few seconds) with the fuel pump off. As soon as it started to die I could keep it running by firing up the fuel pump for about a second and then pull it off. If I left the fuel pump running while the engine is running it would die in a matter of about a few seconds. Along with starting to spew black smoke. Appears to definitely be flooding the engine. |
