Put a piece of electrical tape on the wire or repair it as needed. Then check the fuse block and you will for sure have to replace the main fuse on the starter solenoid. Then it should start and run as before.

I have a 1995 Ford F-150 with a 300 six, it has a full ffront tank and runs like it's running out of gas, I switch it to the rear tank, it runs fine.How do I fix it?


You probably have a bad fuel pump in the front tank. There are other possibilities as well. I have replaced tank switches for this reason also. You need to check for power and ground at the front tank when the switch is in the front tank position and the ignition switch is turned on.

At the wiring connector that goes up to the tank, (on the frame rail next to the tank) the power wire is the RED wire and the ground wire is the ORANGE wire. (The other wires are for your fuel gauge.)

The fuel pump relay will supply voltage to the RED wire for only about 2 or 3 seconds (to prime the fuel rail) when the ignition switch is turned to the ON position, so you will need a helper to check this.

If there is no power, then you should suspect the switch. However, check for power at the switch to verify that it is the switch and not a broken wire between the switch and the tank connector.

If power and ground are both present at the tank connector, replace the front fuel pump.

It sounds like your problem may not be fuel. It could be the ignition coil, rotor or module. The fact that it quit right after you put fuel in the front tank is likely just a coincidence.

I have a 1994 Ford F150 XLT with duel fuel tanks! I have a full tank in the front tank, but when hit the switch for that tank, the truck goes dead! What is the cause of this?


it is hard to say for sure but thhe switch could be bad and the way every thing runs through the computer it turns off(so to speak)instead of smoking the computer.also check wireing undertruck on frame rail by front gas tank for a wore spot shorting out the system.hope this helps.

My poulan riding mower goes dead whether cutting or idling..already checked the gas tank,lines,filter,and carb for trash..all clean...what could be the problem?


Could be bad ignition system. Check for spark when it quits using a new spark plug. Why do you suspect the fuel system? Does the engine quit suddenly or sputter to a stop? Does the engine have to get hot before it will quit? Sudden stop is usually ignition loss whereas sputtering could be either fuel or spark loss. Safety switches--'rider present'--could possibly be a problem and cause ignition loss.
