Primer solenoid is not pushing fuel with red lever in run position (down) but will push fuel in the service/manual prime position (up)
I replaced the fuel pump & vacuum switch in the spring, so I was thinking it?s the primer solenoid or wiring but after performing some test I think I may have air in the system from a cracked hose or just a bad design?
Could it be my solenoid doesn?t haven?t have enough fuel pressure to prime? Or am I getting air? Crazy how manually priming works great but not with solenoid
I performed a bench test on both old & new primer solenoids, both had same results, no fuel flow, I used a clear line so I could see if fuel was trying to flow and nothing, I filled the line with fuel thinking it was getting air and no fuel flow. Is there a chance I bought a bum primer or I burnt it out already? Can?t see it burning it out already, it?s only been on the boat a month or so.
Before I realized the primer solenoid was the problem I performed several test, seems like everyone I talk that has this engine has this issue so im posting my troubleshooting
1. Purple & white wire at key in run & start position 12V
2. Purple & white wire @ solenoid 12V
3. OHMs check on both old & new primer, 6.5
4. Fuel flow with Red lever in up position
5. No fuel flow in down position
Maintenance
1. Fuel lines and ball replaced last spring but I didn?t rule out cracked lines
2. VRO pump this spring
3. Vacuum switch, wire pulled out from unit so I replaced it
4. Primer solenoid this spring
