Funny.... having seen the agricultural engineering approaches to ripping open a hole in the 9-3 floor to get access to change the pump, I was wondering "what about getting a 9-5 cover plate (perhaps with part of the 9-5 floor) and spending the money on ..read more

One stage further. and the two issues.
The P0089 fuel pressure code and engine light gets more odd each time. Last night, as reported, the light was off when my wife drove to her concert. When she went to come home the light was off in the car park a ..read more

The level sensor feeds were the first thing I checked with the Tech2. They arrive at the ECU separately, but Tech2 only sees the combined value. Actually it only reports the lowest of the two, which is why the gauge falls to zero when one goes open ci ..read more

Ah, fair point, it's the first to move to move away from traditional FI type design to the newer direct injection, like the NG 9-5's
You're right about the damped fuel gauge response, you can see that by filling up a car with fuel while its idling beca ..read more

The V6 fuel system does not have a return pipe through a pressure relief valve. The pump is electronically controlled and varies the fuel pressure under the control of the ECU.
I have cans of Forte engine and injector cleaner coming tomorrow.

Can you put the pump into a permanent live situation ?
That way you can circulate your treated fuel without actually consuming any, and perhaps even graph the fuel pressure at the same time.
I would have the charger onto the battery, to maintain state ..read more

No, I didn't. I'll double check the circuitry when it's warm enough for my fingers to grip the multimeter probes...
I have been thinking that the P0089 fuel pressure fault and the level sensor fault may be linked, but I think that will depend on the ..read more
