You can jump the fuel injection relay. This will make the fuel pump run continuously--test only! You can hear the fuel pump run when you try to start the car. You can hook up a multimeter to the fuel pump plug to test for 12V. no volts at plug? then change relay or fuse.

My 92 jetta fuel does not always go on.. when i turn the key the buzz of the fuel pump does not go on. i by passed the relay it goes on i don't know what it could be. some-one told me it could be a ground


If you bypassed the relay and the pump ran, have you checked the relay is getting power, if it is then is then does the relay need replacing? if the relay clicks but there's no power on the output terminals has a fuse gone?

Fuel pump is makeing noises and goes on an off


I think that vehicle has 2 fuel pumps. The secondary pump is located under the spare tire this was on a 92 GLi 16V, I'm not sure what engine you have but worth a look.

No power to fuel injectors or fuel pump


sometimes the relays can be found underneath the carpets or plastic panels under the dash. have you checked the fuses?

Vw Jetta 1992 Deisel no Fuel in the intake line ! I guess fuel pump need to be repaced ?How do I go about it ? I have already changed fuel filter ! Cheers ,Hamid


Thanks for your replay !
I have not been able to get any fuel coming into the Filter ! so I am thinking that problem is the Fuel Pump and I have not been able to find it's location ! I guess it's in the fuel tank and because it's Sunday I can not even find the part ( Fuel pump) !
If you can tell me where it is that will be great,thanks.Hamid
