Tried 4 different fuel pumps. Has 1000cc injectors. Checked voltage, fuel lines, reg, electrical etc. Just leans out 4000 rpm plus. What to check next?

It could be other things but those are the things to check first.

adams355 Member 529 Member For: 8y 4d Gender: Male Location: Brisbane Posted 13/12/18 11:56 AM Author Share Posted 13/12/18 11:56 AM Thanks puff. Changed the filter. Has new lines in the module. Its making plenty of power up to that point. Start throwing the other things that it could be. Might save me some cash that I dont have lol Link to comment https://www.fordxr6turbo.com/forum/topic/94458-weird-fuel-issue/#findComment-1668153 Share on other sites More sharing options...

Get a fuel pressure gauge onto it. Once you've confirmed whether it is losing pressure or not, you can decide where to look.

Puff and I found out the hard way what happens when you have a slit hose in the tank. I had a fuel pressure gauge and when driving he watched the fuel pressure and wideband and noticed we were loosing pressure at about the same rpm.

adams355 Member 529 Member For: 8y 4d Gender: Male Location: Brisbane Posted 14/12/18 01:56 AM Author Share Posted 14/12/18 01:56 AM Yep similar to that but they are clamped. However, its the first thing I will be checking. They were looked at but will double check. Thanks.
