It is a 1990 760 gas we just got it and parked it after driving it for around 100 miles the weather from 10 above to 15 below it was pluged in the time we didnt drive it it stats up no problem but now wont go reverse or forward has fluid in it. runs great wont move?

Sounds like you snapped an axel.

no its not the fuel pump, filter maybe... cant see why though.

how do I change a fuel pump on a Buick electra park avenue?

Make sure the air filter is clean. Have a diagnostic scan done to the engine to see if there are any trouble codes or issues that would reduce your gas mileage. You are getting around 11 or 12 miles to the gallon, which isn't very good. But, judging by the low amount of miles on the car, you apparently do all your driving in traffic, and short distances with a lot of stop and go. If you let the engine warm up for long periods of time, especially in cold weather, that will drop your mileage considerably. Letting a car warm up for 10 or 15 minutes in the winter gets you 0 miles per gallon for that amount of time. Add all these factors up, and figure in the poor quality of today's fuel, 12 miles per gallon is not too far off from what you should be getting. If you have the v6 engine, your mileage was probably around 15mpg when the car was new. Now if you were to take your car on a road trip where you could drive a long distance with the cruise control set on 65mph, you would probably get around 18mpg.

The reset rate for vehicle computers vary by manufacturer, but 50-100 miles sounds good for the relearning process. As with the RPM's climbing unexpectedly, as a precaution I would look for a vacuum leak under your hood... it will be a hissing sound around some rubber hoses, as this can cause the RPM's to fluctuate and possibly give check engine light codes.

Probably not. You can run 'high mileage oil' which helps some and running 10/40 oil instead of 10/30 will help also. Replacing the oil pump and cleaning the intake screen might help too.

if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.

Labatche822,
The process for resetting your Tire Pressure Monitor (TPM) is below.
Good luck, let me know.
Regards.

To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about five
seconds. After five seconds, the display will show
TIRE PRESSURE RESET. If TIRE PRESSURE
RESET does not appear on the display after about
five seconds, see your dealer for service. After you
release the DIC RESET button, TIRE PRESSURE
NORMAL will appear on the display.
The system completes the calibration process during
driving. During the first 10 to 25 miles (15 to 40 km) of
driving, the system will not alert you if a tire is high or
low. After 25 to 100 miles (40 to 160 km), the
system will only alert you about pressure differences of
12 psi (85 kPa) or more. After about 100 miles (160 km)
of driving, the system will alert you if one tire is
10 psi (69 kPa) different from the other three tires.

yes sir i will be delighted to share my idea with you if your car cease every 15 mile then you should check ignite r component is bad thanks

The stepping motors in the gauges go bad. do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options. The dealer charges around $300.00. It will continue to worsen.
