Fans coming on is a system check. first have the computer scanned to make sure no codes are set causing this. have fuel pressure checked. check the relay for the pump. not seen many fuel pumps go and stop intermittently usually they freeze and may start once or twice but just die and dont come back. with a pressure gauge connected see if the problem will occur again while the gauge is connected and loss of fuel pressure falls off. hope this helps

Does 95 Chevy Caprice have an access panel for fuel pump


95 Does not, you'll have to drop the tank to get the fuel pump out, some people have been known to cut a hole by removing the backseat, I do not suggest this as it could cause fumes to come back through the car.

So where is the oil pressure cut off switch located on 95 caprice classic


Oil pressure cut off switch ? It doesn't cut anything off , it's purposes is if the fuel pump relay doesn't work ,when the engine reaches 40 psi oil pressure ,contacts close inside supplying voltage to the fuel pump . Watch this video on Fuel Pump Electrical Circuits Description and Operation from Paul Danner . He is an automotive instructor at Rosedale tech .

Put a lt1 engine in 1994 caprice it skips and wont hardly go up hills and back fires


Hello! are you using the harness for that year LT1? the fuel air mixture is controled by the Manifold Absolute Pressure (MAP) sensor, the Throttle Positioning (TPS) sensor and the Oxygen sensors...When you put your foot in it without O2 sensors there isn't any control over fuel/air mix and ignition advance if the MAP and TPS aren't connected...I'm assuming your using the LT1 ECM...Guru...saailer

Start up


U have 2 seperate problems, the gas gauge issue is caused by a defective sending unit in the gas tank, the cutting out will require u take the car in and have the electronic engine control system tested for trouble codes. Does this car have the 5.7 L engine?

Cutting off while driving


Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted.
