Hello.
So, I'm seeking help for my boat motor.
2009 90hp optimax motor
serial 1b751611
Motor will start up, run a few seconds, then dies. Cycle key, hear the pump run a few second s, restart, instantly dies.
I have replaced the fuel line and bulb.
Drained fuel filter and VST tubes via the hose and bleeder (i think?) Screws on bottom sides that take allen wrench.
I've ordered a new filter but awaiting it's arrival.
Checking out the motor, the fuel shraeder valve on side of VST starts at 0 psi, turn the key and it quickly jumps to 30 then fades to 0. Does not hold pressure.
The 2 valves on the rail by injectors, when turning key, 1 (top)goes over 100psi (max on gauge) And one hits at around 90-95 psi.
As soon as fuel filter comes in, im replacing it.
Thinking i may have a bad fuel pump? Any suggestions which way to proceed? My local marine shop wants $400 for the pump on the bottom of VST and hasn't quoted price for the pump that stands up.
Thanks
