Vs v6 auto randomly stalling whilst driving

[VS_WPN]

I have a VS V6 Auto, i have recently change the heads (ported), lower intake manfiold (ported). About 3 days ago car started stalling randomly. When the car stalls it wont turn back on, i have to wait a while then it'll turn back on. The engine turns over but wont start. I can hear the fuel pump so thats working fine...NEED HELP!!!

Sounds like the dreaded Crank Angle Sensor problem. Check for error codes. link to the how to below.

Also, check out this thread, or perform a search, there are a few threads on the subject, but check for error codes before buying anything or pulling anything apart.

i'd be replacing or check the DFI quick smart. If you can borrow a working one and put that in for a while you will soon see if that is your problem.

Just an Update It was the crank angle sensor. It wasn't getting one of the voltages.

Good job, the good old manual and a multimeter generally makes a quick job of finding the exact problem.
