Possible trash in fuel tank clogging up the pump. All the ethanol in gas these days also seams to do a lot of damage to components. May also be a electrical issue. Just a few possibilities, but a start.

95 Chevy Caprice won't start unless I disconnect the fuel line.


Fuel pump can also cause this problem, You find out if fuel pump is faulty by energising directly fuel pump, and checking fuel pressure.

Check also the fuel line, starting from gas tank, often oxide and dirt from tank can obstruct the hose. Disconnect fuel hose and blow air into it .

Check also air filter and air intake.

Fuel pump on 1994 caprice not pumping fuel. its a new pump. replaced pigtail harness and relay. checked all fuses and used test light to check wires connecting to fuel pump.


I've run into new pumps that didn't work. If there is power at the pump and it is not pumping, then the pump should be replaced, again (under warranty).

I have a 1992 chevy caprice.when car sits overnight i go to start it and it cranks over probably 7or 8 times then starts and runs good.i had a 1977 chevy with a carburator and it fired up in about 1.5 to 2...


No this is not normal at all and you have a problem. FI engines should start immediately and run great without any hesitation. It can be a partially clogged fuel filter. Replace the fuel filter ASAP. It can also be a weak fuel pump or defective fuel pressure regulator especially on a 18 year old car. Fuel pump is located on top and inside the fuel tank. The tank must be removed to replace the fuel pump. After replacing the fuel filter and fuel pressure test will tell you if the pump is going bad.

Keep burning up fuel pumps


Don't buy carter pumps for sure, I know champion makes a damn good pump, but you might want to do some research for yourself. remember you get what you pay for and just replacing the fuel pump is a pain in the @$$ so spending alittle extra for a quality pump is worth not having to change it again

How do you get an air bubble out of a 1994 chevy


You would not. All air in a fuel line will come out when the fuel pump is pressurized. I assume you have tried pumping the gas pedal? Also try depressing the pedal halfway down when you try to start it, if not press all the way down and try. You may have bad gas in the line or a blown fuse for the pump. It is very likely that the pump may be bad. But there should not be any issues with air in the line. You could possibly also have bad fuel injectors.

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.
