I think it is only coincidence, but after changing out my gas tank and fuel pump, the truck won't start anymore. When you turn the key to accessory, all is fine, I have all my electric and the fuel pump turns on. When you try to start the engine, all of a sudden all of the power is lost. The battery still reads 12v, but the wires directly after read 0v. If you bang on the starter, the voltage eventually climbs back up in the wires. At one point, I removed the wire going to the starter and hooked up one directly to the battery from the starter, and had the same results. I also tried putting the screwdriver over the solenoid terminals and that didn't work either.

Does it sound like the starter is locking up and needs to be replaced, or does it sound like something else? This is my last try before I get the truck towed to a mechanic and let them try to solve the problem.

assuming you cleaned and checked your battery connections, it sounds like your battery internally may have a short or a bad connection. The heat from the amerage draw can make the bad connection open and cause total loss of electrical power. I would hook up another battery or jump it and see if it works. If no go then double check and clean your negative cable connections, since you already directly hooked up the positive wire to the starter.

You are correct, I have cleaned my battery connections. I forgot to mention that I put another battery on already to test it out, and I had the same results, so I know it is not the battery. Any other ideas on what it could be?
