Finally got it to start after resetting timing was 180 out, started an ran for 30 mins. turned it off restarted. Son put bed back down on frame started vehicle it ran about 1 min sputtered and quit. lifted up bed checked wiring all looks good but no start and only getting 5volts to ground strap at pump gray wire.
