Looks like you have some water in gas. Check to see if you have a drain on your gas tank bottom. If so, since water settles to bottom, drain some gas out and hopefully you will be getting most of the water out. Otherwise you will simply have to "run it out" or have the station that sold you the gas take care of it.

SOURCE: my 2002 chevy silverado struggles when idling

I had the same truck and it had lean codes.
The intake gaskets go bad causing too much air to enter the chambers. ITs the same gasket for the 4.8 and 5.3 litre motors.

upon tear down i found the fuel pressure regulator had fuel in it indicating the diaphram went bad.

Fixed and everythings all right.

BUT check your codes first I don't want to you to do a tear down with out knowing what the computer is doing first. Auto zone does free diagnostics and tell you what the codes are. Let me know I can guide you from there.

SOURCE: resently ran out of gas now cars running bad / 93 caprice

Change the fuel filter again and if you have fuel injectors, you need to get them sleaned....I believe some of those oil one stop service places will do it. If you have a carb, you need to blow it out....but change that filter....maybe even a few more times if you had that stuff come out the first time.

SOURCE: hesitates on acceleration

Does the car always hesitate during acceleration? If it ALWAYS struggles when it starts or ALWAYS hesitates on acceleration then I would say the issue is fuel delivery. If the problems are more intermittent and come-and-go then it could be an electrical issue.

I would start by changing the fuel filter. Changing plugs, wires, cap, and rotor are all good things to do as your budget will allow. I doubt you will have to change your injectors.

If you end up replacing any rubber fuel line, be sure to use the high-pressure stuff made for use on fuel injected cars.

I hope this helps! -Nick

SOURCE: struggles for power when brakes applyed

I would look for an air leak in the brake booster. These can function when leaking and provide the run issue you are describing.

I need to find a fuel pump relay on a 1989 chevy caprice


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.

What engine of other cars could fit in Chevy caprice 82-85,


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..
