OK, well i put a new one in today to see something, and it started fine, ideled fine and everything. So i let it idle for about 10 mins, take it for a ride around the block and poof! aout 1/4 miles down it goes again. I get out, the relay is hot. I go to put another fuse in and as soon as it touchs it blows. Unless i take the relay out. Any ideas? Its a 89 v6.

Still say it's the fuel pump + wire. The relay on my 4-popper was getting hot as well, but it wasn't the problem. Hope that I'm wrong, though!!!

Is it inside the tank where it breaks?

Nick, do you know how to use a Meter? If so, using one will help you test any wires you are concerned with. It's the only way to for sure troubleshoot electrical problems and come up with the correct answer. If you don't know how, maybe one of your buddies knows how and can help you.

All we can on a board like this is throw our best guesses out.

Here's mine

I'm looking at the wiring diagram, and the wire from the fuse goes to the EFI Main Relay, and the EFI ECU. The wire is the White-Blue one. Pull the relay and the fuse, use a meter to test for a short from White-blue wire to ground. This may or may not work because the ECU is connected and can give a false reading of a short, so you should pull the connector off the ECu to make sure the wirs are in an open condition. If the test open, that's good. if not, it could be bad, or soething is still connected and it is a false short.

Next I'd leave all the things disconected from above and go to the connector at the fuel pump, and discconect it, and test for a short to ground on the Blue wire. To the best of my knowlage just working from a wiring diagram this wire should be open because of what was disconected. If not and it shows a short, inspect it for worn insulation,

That's the best i can give ya without being there to look at it in person. Hope you get it!

I would have to agree. I just went through 2 fuel pump relays in 6 months (no fuses, though) and then the pump let go. Basically, I think the pump was going and putting more load on the relay, overheating it. Changed the pump & everything is working fine.

Thx Steve, you have been a big help. I kinda know how to use a mutli not that good with it though, and i still am not great at reading wireing diagrams =( My brother can help me though. What book are you looking at? I have the service manual for 89.

Nick, I was looking in a Haynes, it covers too many years. If you have factory Toy manuel your good to go, use it. The factory ones detail the wiring much better. Good luck, hope you nail it down quickly.
