Got a 95 caprice classic from father-in-law. Car would not start. I would try the next day and it would start. Then I noticed that if I let it sit for longer than 24hrs it would not start. Have not been able to get it started since. Sounds like it is close to kicking over but not quite enough. After looking at some of these posts, it seems like its fuel pump symptons. My father-in-law says he has had the pump replaced twice. Can I replace the pump myself (how do I get to it?)?. Should I try to replace the fuel pump relay first (and where is it)?
Un plug fuel pump wires at back of tank mounted on the frame at very rear of car. Remove hose clamps at back of tank going to filler tube and vent. Place a jack with a piece of would on the top of it under the center of the Gas tank. Remove the straps that criss cross the tank. Two in front and two in back. Very slowly lower the tank, there are some fuel lines going to the fuel pump that need to be removed if the tank comes down too far you could bend the pump lines. You will need fuel line tools to remove the lines from the metal lines coming from the pump. Once these are removed lower the tank the rest of the way and pull tank out. There are about five or six 10 mm nuts on the top of the pump hold down ring. Remove the nuts. Then slowly remove the pump from the tank. Be careful of the float for the fuel level you may have to lean the pump to one side as you remove it from the tank... you will only need to replace the pump not the whole module on this model..The pump is in the plastic module. Unplug the wires going to the pump then unsnap the plastic top. Remove the filter from the bottom then push the pump out. Reverse steps with new pump.
Fuel relays on this model almost never go bad. If you hear the pump its not a relay. But just because you hear the pump does not mean the pump is working right. It may be loosing pressure...
Loss of spark was also a problem the the 95 4.3 v8. and the distributor located at the front of the engine behind the damper and water pump was the problem and very expensive....
Make sure you have your cars body grounds are clean and tight. rust can cause resistance in these wires thus lowering the voltage to the fuel pump. you may hear it come on but is it a full 12 volts.?? had a nightmare experince with this problem, 4 fuel pumps later it was simply bad ground connections. try disconnecting the power to the fuel pump at the connecter and apply voltage to the pump and see does it run better
If you can hear the pump running then relay is OK pump is in tank, you need to remove tank to get to it. If full tank is very heavy over 7lbs pe gallon fuel. To replace, empty tank so it is lighter and easier to lift. While removed look inside and check for water or rust. clean if needed. Empty tanks contain fuel vapor...be carefulo to keep flames or even droplights away from work area!!! Use a flashlight to look inside. include a new filter.
Had the same problem with mine change coil wire there's no resistance left in the coil wire It won't start it used to start on good days and then get worse as it rained then it wouldn't start at all coil while it was no good how old is your coil wire
Is the fuel pump for the 95 caprice electric or no and does it come with the float attached to it?
