MF 265 issue bleeding after injection pump gasket replacement

[rainman4820]

Edited my post to note that I did not go through the entire pump, just replaced the throttle and stop o-rings and lid gasket so i don't believe timing is an issue.....Just finished replacing gaskets and reinstalled pump. I opened the bleed nut on the top/side of the pump and pumped the lever until fuel came out. I loosened 2 of the nuts holding the injectors and pumped the lift pump ( number of times) but still not getting any bubbles or fuel. I moved the fuel stop lever and throttle several times and still no fuel. I have not tried to turn over the engine yet. I am certain the fuel stop was engaged when i closed the lid. Did I miss a step or do I need to pull the top and assess the guts?

The lift pump will not put fuel up to the injectors, the injection pump does that, the lift pump only gets fuel to the injection pump. Cranking with the starter (or tow starting, if not a MultiPower transmission) does that.

As Jim said the engine must be cranking for the INJECTION PUMP to get fuel to injectors, the feed pump will not do that.

Thank you for the quick responses!

Thank you for the quick responses!

Fuel shut off in the run position and throttle half or better.

Did exactly as you prescribed and she started up ! I just want to say thanks for taking the time to share your expertise. Your efforts saved me money and time but more importantly, gave me a chance to have a deeper understanding of how these machines work...always looking for an opportunity to learn!
Best!
