On a bosh fuel pump (3 tit) does it cut out if it cannot get fuel?? I realize if it is intermittant it is probably a loose connection, loose or bad relay, loose pin on board, or dirty fuse on board, etc.
i am at work, and i am not so sure i will make it home tonight, i have a few tools, but no electrical stuff with me. i was wondering .... what would the pump do with good power and a clogged line?? i made it half way to work and the pump cut out 3 times within 1 min, then dead. i pulled over checked the pump and all connections tight. i tried to start it 4-5 times, heard the pump run for 1 sec then dead. crawled under and shook the filtre and banged on the pump. it started but would not idle. i then loosend the clamp holding the pump and turned it upside down. car started and kept strong at high idle but started to choke below 3500 rpm. I risked the drive into work, and made it idling between 3500 and 4500, it would start to cut out and i would downshift jump the rpm and it was ok again. welcome to my life |

Its either the fuel pump, or the fuel pressure regulator which is unique to Ljet...its a rising rate fuel pressure regulator.

Rich tommorow, my plan is to replace the fuel filtre and then run a jumper to the fuel pump from the coil + lead. if it has any cutting or stumbling sounds it is the pump right. if it stumbles but the pump is continues sound. Then i have a clogged sock?? sound like a good approach? |
