On the third pump? That sucks. OK, I took the week off to get this thing running. I follow the fuel line from the tank and it goes to the filter/seperator. From there, goes over to the other side of the engine into a blue thing that looks to be a cooler to me as it has water going through it as well. From there it goes to the pressure reg then to the engine. I am at a loss as to where the pumpis actually located. I don't hear anything when I turn on the key. Checked all fuses and can't even find one for a fuel pump. Been so bloody hot out I haven't spent too much time on it until now.... Did replace the starter to get it turning over and it will fire up on ether... so it isn't a spark issue. Will post results after tonight if anyone cares... Plan is to be on Saylorville this weekend (or sooner)

if it is a cool fuel system the regulator is mounted on top of the fuel pump and it has water hoses going in each end of the pump

YAY!!! Found the fuel pumps! Guessing one is a lift pump and one is a pressure pump... They both test good but do not turn on with ignition. I traced a gray wire back to a relay in the box mounted to the port side of intake. The relay in there is triggered by a dark green with stripe that goes to ECM. I manually powered the pumps and tried to start, no go. Guessing the ECM isn't getting power or it is bad. Anyone have a schematic for this? That would be SUPER helpful...

Also, hopefully not related, whenever I turn the batteries on the navigation lights are on. Most switches are worn off so I don't know which is nav lights, but either the switch is bad or wiring is jacked... Gonna pull the switch panel and see what skeletons come out...
