Suddenly no fuel

[iBoostDSM]

The other day while driving to work, the engine suddenly cut off. I coasted to a stop and tried starting it again. But didn't here the fuel pump. It also isn't building any fuel pressure.

After getting the car home I swapped in a Walbro 450, took the 255 out and put in a new fuel filter thinking it may be that. Nothing. I did also notice I blew the fuse inline with my fuel pump rewire. Replaced that and still nothing. I swapped out the relay for my rewire and still nothing. I can hear the fuel pump relay under the dash clicking just like normal when I turn on the fuel pump with dsmlink.

Any suggesting of something that it may be? Or something to try.

Thanks

Have you pulled the ecu to inspect caps? Sounds like an ecu issue.

If you have a multimeter you need to test for power and ground at the pump. If no power is present than check for continuity from the pump to the relay. Than check for power and ground at the relay. This is something that you are going to have to get your hands dirty a little, it would be impossible for anyone to tell you exactly what your problem is.
