It has been so cold i just have not had the chance to check every thing, but thanks, atleast now my thoughts where confirmed.

Unless you have a particular symptom or a 'service engine soon' light on I would go buy the following maintenance schedule:
1. Change fuel filter EVERY 10,000 miles.
2. Check air filter at the same time. (held up to a light, you should easily see the light through it).
3. Replace spark plugs EVERY 15,000 miles and plug wires (cap & rotor if so equipped) every 30,000.
4. Don't forget tire pressure - this can have a drastic impact on MPG. Many 'newer' tires require a maximum 44 psi, yet many of us still go by the 35 psi standard of old never looking on the tire. All tires are clearly marked as to maximum psi and remember the average tire gains 1psi of pressure for every 10 degrees.
Hope this helps.

SOURCE: New fuel pump on 92 roadmaster fuel pump has power

take a test light and make sure you have power to the injectors. then put the test light to the positive side of the battery and check for injector pulse from the ECM by trying to start the vehicle and see if the light flashes.

Engine cranks will not start changed fuel pump fuel filter even ecm still nothing can hear pump start when key is turned on.


I have a 92 Roadmaster. I was pulling my hair out by the roots trying to figure out what was wrong until I jacked it up and traced the plastic fuel line. it was caught between the transmission crossmember and the chassis and was partially crimped, I'd had the ****** mount replaced a month before! So I loosened the crossmember moved the gas line, retightened the bolts and that worked for me. Good Luck!

The rear window shattered on my 92 Buick Roadmaster Station wagon and when they came to put the new glass in the hinges were rusty. I can't find new hinges anywhere. What do I do?


just get used ones, make sure you inspect them before buying to make sure they still have grease and are not getting rusty, and sign of rust on them is a bad sign...

You may snear at used parts, but in alot of cases they are better used than new.
