Time to find someone who knows what they are doing .

I had an issue with an engine not starting once and what i did was swap the fuel feed lines on the engines. And the motor started right up. Ended up being a broken Fuel pick up.

My lines coming out of the tank didn't have enough length to swap pick ups so i just went to the part store got rubber hose with a union type fitting and extended the fuel line.

This will help you find out if its a Fuel issue

Ok, turn key and no fuel pump kick on, pressure tested Schrader Valve and no fuel pressure. Swamped relay with good side motor and no fuel pressure. So I'm down to a blow fuse which I can't find the elec fuel pump fuse, or fuel pump is bad. Any idea where the electric fuel pump fuse is at?

I checked with a fuel pressure gauge and nothing. Turn key and no fuel pump prime. I swapped the relay from the working motor and still no fuel pump. So I think I'm down to fuel pump or fuse. I can't find a fuse for the elec fuel pump and can't get a reading with volt meter.

What do you mean when you say "i cant get a reading with a voltmeter". As in there is no voltage present at the fuel pump connector with the key on? Or physically cant get the leads connected?

There should be a fuse like fixx said. Actually, I think there are 2 or 3 fuses on that engine. At least 1 being for the fuel pump. Can you trace the wires feeding the pump

in that box...they might have weather caps on them to prevent corrosion...pop thecaps off and look for a fuse under it..

I think the fuses are mounted to the lid of the ECU and main wiring box and all those are good. No pressure in rail and noise from pump when key turns on. Did spray starter fluid in spark arrester and it fired. So gonna swap good elec fuel pump motor with bad and see if she fires or at least comes on and pressurizes system.

Like said ignition switch or ground!!Lanyard??????????

also check the circuit breakers on the dash,,could also be a fuse panel in the boat..my formula has 3 of them..

BTW @ he fuse's did you test them for power ? just looking at them does not mean they are good,,i have found blown fuse's that looked good but were blown..

also make sure the main plug engine harness is tight,,i have seen those come loose and cause all sorts of problems..
