It sounds like you know a lot about cars, let's start from the obvious, have you checked your grounds? If it rolled those can be exposed and touching something they shouldn't.

SOURCE: 1991 Accord, ECU fuse is blowing, checked wire

Hello! Fuse #28 (10A) feeds two wiring runs...It powers the fuel pump, and the Electronic Air Control Valve (EACV)...Either of these two devices can be shorted to ground or the harness that feeds their power...

Pull the relay...Pull the fuse...Disconnect the connector from the EACV...It is located behind the PCV...Wire colors are...Yellow/Black and Black/Blue...

With ohm meter on X1 scale and one probe to ground...Measure from the Yellow...then the Yellow/Black at the relay...You will see the fuel pump winding resistance...But not zero ohms...

Wiring harness shorts are hard to find...So stop there and tell me what you read...........saailer

SOURCE: Hello, Im a US Marine

That fuse also supplies illumination to the radio, hvac controller, cup holder and cigarette tray. I think the best thing to do is start unplugging each one of these until the fuse stops blowing. Then plug the last think in that you unplugged to make sure that makes the fuse blow. If you suspect the instrument cluster start with that first.

SOURCE: I have a 1990 pontiac

An internally shorted relay can blow a fuse. Remove the relay and try another fuse. If it blows again, then you have a short to ground in the fuel pump wire. You'll have to trace out both ends of the relay, the supply to the relay, and the feed to the pump to find the short. If you have a volt/ohm meter, you can use the continuity function to measure resistance between the wire and ground. You should not get continuity between the fuel pump wires and ground if the fuel pump is not plugged in.

How to change petcock in a 1992 quadrunner 250


Either empty fuel from tank, or remove tank. With petcock in closed position, remove fuel line going to carb. Turn petcock (but if so configured) counterclockwise, until petcock becomes free from bottom of tank. You can buy and install a rebuild kit, or change assy if needed.

1994 suzuki quadrunner lt f250 wont run


Hey Marty,
An internal combustion engine requires three things to run..(if all the internals are good)..
1. A properly timed spark.
2. Adequate compression (>120psi).
3. Proper air/fuel mixture.

Start by eliminating one of these at a time...(get a professional to clean and set the carb), install a new spark plug. Get a new fuel line.
