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? |

QUOTE(john rogers @ Aug 13 2004, 04:30 PM) Sounds like someone has jumpered the fuel pump relay with the extra 12 volt wire. I'd say check the fuses on the relay board and their connectors, probably replacing the fuses anyways. You could also try another relay or put it in the headlight relay socket to see if the light pops up and see if it is good? When you turn on the key the pump should only run a second and then stop and then run when cranking. You can also check the voltage to the inlet of the relay with a volt meter when someone turns on the key to see if you get a jump. Good luck. Nice Job! One of the fuses were corroded horribly. Worst I have seen. My pump doesn't seem to quit running. It just keeps running as long as the key is on. Is this because it is running off of the jumper wire? |
