Year of Manufacture *: 1992
( Optional ) Engine Code or CC: 3500

This has running issues, and many problems, fuel pump i think being one of them......

Blue trace is fuel pressure, green trace is pump current

The lower capture is the pump current zoomed in x272

which appears to have 12 segments...

Fuel pressure seems erratic and on snapped throttle have a difference of around 14psi!
