trouble shooting, I plug return line to deadhead pump, to check pressure, old pressure was 15 psi. boat would start,would not idle or stay running. i get a code 22 low voltage on tps , would that have any thing to do with fuel pressure? i read comments they rebuild reg.still not wright fuel pressure, or find reg, kit with 30 psi spring. so i was thinking about an external reg. in return line. would that work?
I plugged return line to deadhead pumps to check fuel pressure. (trouble shooting) my pressure was 15 psi boat would start, would not idle or stay running. i read comments they rebuilt fuel pres reg. or having trouble finding a kit with 30 psi spring, still not right.so i was wondering if a external reg. in return line would work? i get a code 22 would tps have anything to do with fuel pres?
