Fuel starvation

[srelegante2]

Fellas-

I tore into the 955 a few weeks ago, in order to take care of a few things.

I disconnected the fuel lines (quick disconnect) in order to take off the O-rings, as they needed replacement. In the interim, I have been diagnosing the much-written of charging problem.

The fuel lines were disconnected for 7-10 days, while I went to get the O-rings.

We worked on it last nite, and it looks like a bad RR (big surprise). However, it fires and runs, but is starving for fuel. Idle is ok, revs ok, but big gap in the middle.

Q: Is it possible the weak battery is screwing up the FI system? Or an itzy bitzy spider found it's way into my fuel lines? Or other debris? It did not do this before I started this project.

Where do I start diagnosing? I will put the battery on a tender to keep it strong-maybe that will help.

Thanks!!

Weak battery can really screw up these things, it doesn't allow the FI to save it's trim state. Get a full battery on it and try the adaptive tune

I switched the fuel lines, and bingo-much better.

Still need remapping, throttle bodies and RR/Stator updates-but at least we can move forward with those.

What a relief.

Thanks!
