1986 Porsche 944 N/A l, Starts but dies right after

[reesescupsftw]

Hello everyone,

I need help on this issue, I’ve read all I can on this issue on multiple forums and replaced everything suggested that are remotely close to my issue.

My car will start, then run for about 4-6 seconds then die. HOWEVER if I start it and hold the barn door about half way open on my AFM, it will idle, but as soon as I give it gas it dies. So I bought another AFM and it still does the same exact thing.

It does have a aftermarket alarm installed by the previous owner. And it works.

Things I’ve replaced,
AFM
Battery
All vacuum lines to silicone lines
Starter
DME relay
Fuses for relay and ignition

Idk what else to try, what throws me off as well is the fact that I can hold the barn door open and it idles fine. I adjusted the idle air screw on AFM and no luck either. I was hoping one of you guys had had this same problem and solved it.

This is the 911 tech forum- perhaps post in 944 forum?��

What about the fuel pump? Maybe running when you crank it but not after its started
