Car is a CIS 3.0. Tried to start it last night and it wouldn't start. Noticed I couldn't hear the pump when I turned the key. Check relay it was good went to the pump and while trying to get the cover off a sliped and smacked the cover and it started working. Pulled it out all conections look good so I asume I need a new pump?

Could be a few things....bad ground...which can be fixed by finding the connector and cleaning up or tightening.....could be gummed up internals....best to bench test with a techron laced fuel and recirculate....
Make sure you are sitting down when you price a replacement.... Also CIS pump starts up at odd ball times.....hot starts require a high pressure that is kept up by a chack valve in the neck of the pump. You can defeat this by lifting the flap in the air box. Cold starts get an assist from the cold start valve. |

I had a feul pump problem last week.
I picked up my car from dave a week ago. I drove it home and I think the rain gummed up some connectors. But after panicing at first I then cleaned all the connectors and put them all back. Started up and ran fine. Still not exactly sure what connector it was since I kinda did them all. But yeah I would make sure all the wiring is clean and has a good connection. Even though they sometimes look clean they can have residue underneith. |
