94 Golf CTI Fuel pump problem

fuel pressure regulator to bring down pressure for carb usage can still use the electric pump

do you have a spark at the plugs ? if so ..main cause is fuel pump connector plug under car by fuel tank . test this bye getting a Friend to turn ignition on but not start whilst you listen under car for fuel pump buzz. if you hear a buzz forget solution 1 if no sound try solution 1. move the plug (4wires in front of fuel tank ) about then try again . if you have a tester and power is passing this point (pump side) then it fuel pump faulty.. solution 2 crank sensor which is on the lower half of the engine block .. hope this helps

Could be fuel delivery issue. Does the car have enough fuel in the tank? Check that the air filter is clean and if it is, than check the fuel pump. Do this by turning the key to the on position and listening for a buzzing sound for a few secconds near the back of the vehicle. If you hear the buzz, than the fuel pump is fine. If all this fails to help, try and have the fuel filter replaced. Good luck!

A Battery?

I would suspect a bad fuel pump. Fuel pressure test will confirm this. Can also be a clogged fuel filter, or bad relay.

check the fuel pump cut off oil pressure switch and the wiring to it. the switch is located near the oil filter.

sounds like you have a huge vacuum leak at the engine, check under the hood for a sucking noise, I think you will find one.

Time to change the intank fuel pump, it may last a day or longer. I thought longer and ended up broke down 250 miles from home and had to pay a mechanic to replace instead of doing it myself.

Mine did that to me about 4 months ago. I started by changing the fuel filter it ran great for a month. but by doing that it released all the pressure off of the fuel pump which then went out. If you run your vehicle below 1/4 tank it starves the fuel pump. The pump needs that fuel because; The fuel is the lubrication for the pump. Running your tank down consistently over a period of time will short the pump out faster.

turn the ignition to the ON position and check to see if you can hear the fuel pump making a buzzing sound. if it doesnt make a buzzing sound, the the fuel pump isnt working. if the fuel pump sint working, then check the fuse in the fuse box under the hood.
