  1. I have experienced the same problem and it turned out to be low fuel pressure. The motor would always start from cold but, when hot, I'd crank the motor for ever trying to get it to start - without success. I'd then sit for an hour letting the motor cool and then, eventually, it would start. I thought the problem was I was flooding it!! But here comes the solution... I ran a temporary electrical circuit between the battery and the pump when the motor was hot and surprise, the restarting problem disappeared! The bottom line - the electrical supply wasn’t sufficient to generate the 115 psi output from the PI pump. By bypassing the existing circuitry solved the problem. As a permanent fix I put a relay in place - using the 'old' electrical circuit to operate the relay, and laying in a new circuit from the fuse block to the pump. Hope that helps.
