How to install a new fuel pump on a 1985 Chevy,305 V8,

No there is no panel the fuel tank must be removed to replace the pump module. Easy job have done quite a few. about 3 hours.

buy a multi meter, and start probing :) there are tons of educational vids on youtube on using multimeters to diagnose and fix electrical problems :) basic multimeters for diy cost almost nothing.

Hope this helps (remember to rate this answer).

The relay for a 305 V8 is under the hood on the passenger side fender. It is a black 2" cube hooked onto a bracket. There is a red test wire and clip coming from it. You can bypass the relay by attaching a short wire from the clip to the positive terminal on the battery. Have some one kneel by the gas tank while you test the relay. If it comes on (the pump in the tank will buzz) then the relay is bad. A new one is $10 at the parts store. Just swap it out.

possible ignition coil pack breaking down...unit cools off them fires plugs again...fuel pressure is a concern also ..possible failing fuel pump

almost every rear drive drive full size used the 305 V8, so u can get an engine from a Buick La sabre, Pontiac bonneville and firebird, also Oldsmobile 88, and don't forget Camaro. any 305 chevy V8 will bolt in, also the 350 V8 will bolt in, this is a much better choice..

Also do not let tank run low because fuel in tank keeps in tank pump cool. This is why the pump is in the tank.
