I hope some one can help with this. I have a 1989 bronko, 302 engine. The fuel pump relay has fried twice. After I replace the relay it seems everthing is fine. But after running for a while the fuel pumps do not shut down even if the key is out of the ignition!!! This fries the relay again.

ok first help is it is spelled bronCo. j/k now it sounds like a simple bad fuel pump. hopefully for you it is the exterior fuel pump and not the in tank. i took the outside fuel tank off and put an aftermarket fuel pump that attaches to the frame and not the tank. i got a couple of extra MPG's out of it to.

The contacts in the relay are welding together due to the excesive amp draw due to a fuel pump going bad . If you have access to a dc amp clamp you can check the amp draw on both with it running and the one that is very high will be the one you have to replace . Hope this helps also a very clogged fuel filter will cause the amp draw to go way up because the pump has to work alot harder to force the fuel through the filter .

yes yes yes blade is good that is what is happening if it is a bad fuel pump it is because you leads have siezed together and now you are always drawing power to it. get your self a new filter and it should fix the problem.
