New engine starts but dies
 

what do youthink the problemis. It starts and I can take it to ab out 3 then it just stumbles down and dies

this is a new rebuild too

did you set the crank angle sensor? make sure all sensors are plugged in.?

they are plugged in

sounds like a major vacuum leak, check all the intercooler lines/hoses and brake booster line and be sure the AFM is plugged in.

will do again:) and keep you posted

Yeah I agree check you vac. lines, I had the same problem with one of my sr20'd 240's,
it turned out that a vac. hose had poped off.
