On my way to the mechanic yesterday, the motor just up and quit. After towing to its destination, first thing we thought it was the fuel pump. So we ran a test via the pump prime plug on the fuel relay switch. Then the pump worked, so we thought it was the relay switch. Went out and got a new one and the same thing happened, no fuel getting to the carburetor. The only way we can get it to pump gas to the carburetor is by placing a hot wire in the pump prime plug, but the fuel stops right at the carburetor. No fuel makes it to the injectors and all this really only happens when you run a wire to the pump prime plug on the fuel relay switch. With the ignition nothing works: the fuel pump doesn't come on to even send anything to the carb. Is there a fuse that I'm missing? We have checked everything via placing a hot wire to it and it all stops at the tbi, even with hot wires. The motorhome fires right up the minute you pour a little bit of gas into the carburetor, but the minute you run out its a dead stick again.
Hope this makes sense, I'm not sure what else to do we spent 6-7 hours troubleshooting and still nothing. If there are any questions, I will be checking quite often.
Thanks again.
