Hello Skullzaflare and thanks for the reply and the suggestion. I did try the water to cool down the pump but got mixed results. I'm certain heat is part of the cause of the failure. When it's cold it starts fine. It only fails once it has been running for a while. It could be I need to get a bigger bottle of water..

Here's an interesting update. Once I warm it up I can stall it by popping the clutch while in second gear and leave the key on - never removing power from the fuel shutoff valve. It starts every time. I think it could be the shutoff valve that's failing. I also monitored the voltage to the shutoff valve and the voltage is the same as battery voltage. ( I'd seen a post that addressed a problem with voltage drop to the shutoff valve - so that could be a source of trouble just not in my case. ) Oh yeah, when I stall the engine and restart I can do that several times with no failures. As soon as I turn the key off and try to start it fails.

BTW, this response has been on my desktop for a couple days and I always had something to add to it so I never sent it. Sorry for the slow response and thanks again.

I plan to try to remove the fuel shutoff solenoid in place and without disassembling too much of the pump. Anybody done this.

I have another question - can anyone tell me what the connection right above the fuel shutoff is? I've seen it on some other documents but none identified it.

Thanks
