    S52 cutting out then die now no fuel

    Was on my way to school this morning and my 99 S52 OBD1 swap started to cut out at steady throttle for a minute or two then just completely died on the freeway.

    Car has intermittently died at idle 3 times in the last month and doesn't start for 15-30 seconds then started up


    checked the CPS and it was at .771 witch is way to high so I replaced that. and still nothing!

    no fuel coming out of the line. Checked the relays and they are clicking on


    No really sure what to do next.

    Sounds like a dead pump.

      Yup, sounds like pump related. It is also 318 specific.
