80 SC Hot start problem

[lochrie2]

So I have developed a hot start issue. Car starts fine cold with the cold start valve but after driving for awile it doesn't start. I hooked my gauge up to the main supply line before the accumulator ran the FP for a few seconds and after shutting down the FP watching the gauge the pressure drops to 0 immediately. Is this clearly a failure of the check valve on the fuel pump?


Thanks, Chad
