95 Buick roadmaster Gas consumption

I would say that any car in this year range and milage for $2300.00 would be a good deal as long as the engine and transmission are in good working order.

Things that can be wrong as long as the car rools fine are the timing chain and exhaust restrictions or leaks. Dirty or leaking fuel injectors can too if the car has good power and doesn't lag at off idel ( like a timing chain loose will do ) oil pressure or too heav oil or oil that hasn't been changed. low tire pressure is worth about 3 MPG Timing chain can be 10 easy as stopped up exhaust. the car runns stronger with the pipes unbolted from the engine then theres a converter or muffler problem. If the pipes are good it'll not make any different except it'll sound like a race car. ( might seem faster but it will be faster if the pipes are stopped up. Race cars go faster with open pipes as the engine has been modifed to run better with open pipes but an ordianry car will have little difference until it's revved up real high.

You need to identify if the problem is fuel or spark. Try pumping the gas a few times while cranking. It's possible that since it has sat for so long, the vaccum has been broken and there's air in the fuel line. If you're able to start it after pumping the gas, you've solved the problem, if not, you've likely ruled out the fuel problem and identified it as being spark. In that case, try pulling the wires and check the plugs for rust or other debris. If they're dirty, wipe them off or if they're really in bad shape, replace them.

this is not the gas gauge, this problem is caused by the gas gauge sending unit inside the gas tank, drop the gas tank and rep[lace the fuel pump/sending unit module, about $200 for the part from rockauto.com.

Well the cable from the trans to the gauges is loose is the only thing it could be.

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.

Try backwards flushing heater core first before replacing it.Be sure temp blend door is working and if equiped, the coolant flow valve also.Hope this helps.

You have checked for spark, Fuel Pressure, Injection pulse? Don't worry it will run. It was made by the General!
