240 efi won’t start?

[paulc229]

Hello all, seems like this summer I’m on here every second day looking for help, I really do appreciate all that have helped so far. I was having a problem with engine cutting out at wot, as time went by started getting harder to restart, was out yesterday running 1500 rpm, and it just died and would not restart. I did notice the last couple times, the lift fuel pump( I think that’s what it is, pic attached) was clicking louder than normal when I turned the key to “on”. Ordered a new pump and filter hopefully be here soon. Is there anything else that would cause this?

Yes, that is the lift pump. It feeds the engine driven pump. It feeds the injector (VST) pump.

Same some $. Before replacing an item, check its function. Check fuel delivery from the pump. Maybe the problem is the fuel filter. Looking at 1st filter. There are 2 more.

Thanks Tim, I ordered both, because it was making some really loud clicking noises that didn’t sound normal or good. When I install do I have to bleed the system, to get air out?

No bleeding required.

Thanks, a buddy had a universal 12v low pressure pump, I hooked it up and it solved the problem started right up, but still going to switch it out when the marine one comes in.......
