Unfortunately the EDU gizmos do seem to time out .
As in Many die in use... as the years pass by.
Best advise would be to source a still working used one..
(Or find a decent Electro wizard to try and patch it.. Its a Japanese made item.. if that helps..Could also try the old Reflow the solder joints trick??)
and hope it continues to work during your ownership of the car.
This is the symptom of the power (12v) dropping out -- leaving the EDU "thinking" the car is just started so it cycles the low-fuel light & check radiator light on, and then the gauges are back to normal...
I (kinda) hate to just run an independent hot lead to the EDM to see if that solves the problem -- it's too easy for me to say I don't see a back feed issue but...
One could try running a hot lead from the fuel pump (or other ignition switched circuit to the EDM, add a diode in the line so a "back feed" couldn't occur when turning the car off.
It may be time to start thinking about building my own gauge cluster. All I really want is speed, rpm, volts, temp, oil pressure, vac/boost, and fuel quantity. All the other bits I can do without. Just need a VSS signal to the ECU. Everything else would be better served with little round SVO gauges
that weren't blocked by the steering wheel... ;ol;
I fixed this on mine by reflowing the solder joints on the EDU connector. Used to drop out regularly but has been good now for about a year. A lot of electrical glitches on these cars seem to be caused by bad solder joints. (Early lead-free solder?)
Just acquired a 1994 9000 non-turbo 5-speed and will be refreshing it after sitting for over 4 years. It sat near salt marsh for several years so it has surface corrosion on various places and it needs some major cleaning and cosmetic touches. The clutch needs work, no fluid pressure. Got it to...
Hello ...I'm seeking power steering fluid recommendations. I've seen the official spec that states using either Saab or GM fluids. The GM fluid is the Texaco TL 4634. I read a thread where someone stated Dextron III is very similar to the GM power steering fluid.
What power steering fluid...
