Car will not start. My '92 Buick Roadmaster won't

The battery connections on those are prone to corrosion and poor contact. Take the connections apart and clean them thoroughly. Use a wire brush, use di-electric grease on them.

If i changed the fuel pump relay plugs in my '92 buick roadmaster and it still will not start, but i have all power, do i need an ignition module?

first off you need to know if your problem is fuel or need to check to see if you have good spark at the plugs and fuel.if you have spark then you can spray throttle cleaner into the intake while someone tries to start car.if it starts and runs a little then you have a fuel need to make sure the pump is running.listen at the tank to see if you can hear the pump running.if not then you probably will need a fuel pump.

91 Roadmaster, Auto A/C, no power to A/C relay. What should I check first?

1- Check the fuses, switches etc (its the most obvious places, and cheapest to check)
2- Check your freon - if you have an a/c gas leak, the pressure switch on the gas line (a/c gas, not fuel!) cuts out, causing the relay to de-energise. It's a safety measure to prevent damage to the compressor if the pressure is too low.

I hope this helps!

My gas guage dont work how do i fix it?

I know EXACTLY what the problem is. You are not alone. Many Buick Roadmasters had this problem. Its in your fuel tank. The fuel bob gets stuck and even sometimes in the filter it cuts off the gas to prevent strong acceleration. This is not a cheap fix unless you do it yourself. The gas tank either needs to be removed or cut open. This is coming from a prior Buick Roadmaster driver. Call your Buick dealer, they can help you out.

I hope this helps.
