Fuel Gauge of concern in a start and stall situation?
Hi All
I have an 80 US 928 Automatic that I picked up as a project. It sat for years and didn't have a very motivated owner.
I'm troubleshooting all the start and stall symptoms these 928's are known when they have not been maintained.
I've replaced the XVI relay, and am ordering the fuel pump relay. After reading some of the other threads about jumpering the relay, I've found that it powers up. I've checked the 14 pin connector and plan to clean that puppy up this evening. Even the green wire, which I intend to order. The non distributor side had a harness that fell apart when I touched it. I have a male end I plan to test coming in tomorrow from Roger. I cleaned up the spade connectors and plugged then I'm anyways and wrapped some shielding around them. But still it will start and die. It will run with starting fluid, and before you guys come down on me for that, I only did that twice and for a minimal amount if starter fluid! No mas I know!!
One thing I do notice, that even after adding 5 gallons of gas, the gauge is pinned below empty, not even flashing- if it does that. Is that part if my problem? Aside from that, all the idiot lights work, warnings and all light up. The instrument lights as well as the lights in the shifter and the radio console/climate controls do not come on. It appears the oil pressure gauge and everything on that side works, rpms yes.
Is this fuel gauge issue related to my poor shark's starting and stalling issue?
I still have tons of testing to do on the rails and injectors - but I wanted to throw this out there as something I might look into.
Thanks guys.

Quick follow up:
I found a thread that showed how use a jumper in the connector to the sending unit, and if jumped properly with the key on the fuel gauge should jump up to full. If the needle jumps, the gauge apparently works and the sending unit does not.
At any rate, mine needle didn't move at all. I cleaned up all the connectors and fuses, replacing the broken and corroded ones.
Back to the trouble shooting.

Get a new green wire many Porsche shops (911s used a similar wire for years) will not even bother testing a car with an old green wire.....far too many intermittent problems wastes way too much time.
Fuel level gauge has nothing to do with running until you run out of fuel.
