Car Starts but doesnt stay on...

[91NCGST]

Hey guys...Im trying to figure out why my car doesnt stay on when I start her. I have 550CC injectors...At first I thought maybe I was flooding the engine or not getting enough spark...But I did a tune up recently....It turns over freely and everything. She evens sounds like shes gonna crank and run but it kinda peaks and dies shortly after..Doesnt even run for a second. Any opinons would be helpful. Thanks _eddi

Sry forgot to include specs...I just bought this car..So cant tell much about work previous.

MafT
550CC injectors
FMIC
Bigger PUmp
New Plugs
He also capped off the vaccums at the TB those four or five lines at top.

I think it is too rich. you can disconnect the fuel pump & start the engine it will start again. I am facing the same problem & installed AFR but I am still not able to solve the issue.

first thing i would do is to check to see if getting spark. if getting spark, and is still doing the same thing, then check compression.

Is the MAFT set correctly for your injector size? Also, do you have an aftermarket fuel pressure regulator (AFPR)?

No, I dont have an FPR. (aftermarket). I set the MAFT to 550CC
