Strange Fuel Pump Issue, Help please - FIXED! Options

[flat4tom]

Hello all,

Got my 914 back together today. Here's a list of what I've done since I brought it home...

Fixed front trunk release so it will open.
Pulled gas tank. Tank is clean, no rust, fuel sock there in good shape.
Replaced all fuel lines under tank.
Pulled injectors and sent them for servicing.
Replaced all vacuum hoses.
Tightened all intake runners down - they were loose.
Removed and cleaned the throttle body
Checked the TPS and adjusted
Replaced the throttle body, installed a new TB gasket.
Removed and fixed inoperative AAR.
Replaced the spark plugs with new NGK's
Reinstalled cleaned and serviced fuel injectors.
All new fuel hoses in the engine compartment.

She runs like a top now! No vacuum leaks. No missing. Idles smooth. Took her out for a spin and to get some gas. Has a strange issue now with the fuel pump.

The fuel pump has been relocated to the front under the gas tank - recommended relocation spot. I can now hear the pump running while the engine is running. Seemed like it was quieter before... anyway...

While driving down the road straight - all is good. If I make a turn to the left the fuel pump seems to cut out (the sound changes) and the engine starves for fuel.
Right turns, no problem. (IMG:style_emoticons/default/WTF.gif) If it's idling in the driveway and I turn the wheels, no problem - fuel pressure remains constant. I wish I could check my fuel pressure gauge while driving but it's mounted to a fuel rail.

Any thought why the pump would cut out on left turns?? Any suggestions on where to look for this?

I am so close to being able to drive her!!... (IMG:style_emoticons/default/driving.gif)

The problem might be the non-stock wiring added during the pump relocation. Start the engine and wiggle the wires at the pump and where they tie in to the factory wiring to see if it makes the problem come and go.

If that makes a change, there's your problem to fix.

Sitting for three years with old gas can cause varnish and crud to cake in your pump or rust to form in your tank. Did you drain your tank and get new gas?
