marcus Posted June 6, 2005 Share Posted June 6, 2005 when i turn the ignition, the fuel pump primes BUT (i have a fuel pressure gauge) and the fuel pressure goes up as it usually does but then it goes straight down to 0 again. when i start the car, it seems hesitant and it has cut out on me 3 times today anybody have a clue what it is??? im thinking fuel pump???

sime73 Posted June 6, 2005 Share Posted June 6, 2005 does the pressure drop as soon as the pump stops priming?? fuel regulator ?leak ?fuel pump relay? Link to comment Share on other sites More sharing options...
marcus Posted June 6, 2005 Author Share Posted June 6, 2005 dont think itll b the regulator as i have a pbwer boost vavle not a leak, ive looked everywhere an the petrol aint goin down the fuel pump relay, i was thinking this because my dad put his ear near the fuse box and a relay clicked when the ignition was turned on an the fuel pump primed but then it clicked again when the fuel pump turned off an the pressure goes down, dad seems to think that the relay should remain open once the ignition is on an not click off like it is doing Link to comment Share on other sites More sharing options...
