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. Link to comment Share on other sites More sharing options...

Its making plenty of power up to that point. Start throwing the other things that it could be.

Get a fuel pressure gauge onto it. Once you've confirmed whether it is losing pressure or not, you can decide where to look. Link to comment Share on other sites More sharing options...

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.

However, its the first thing I will be checking. They were looked at but will double check. Thanks. Link to comment Share on other sites More sharing options...
