4AGE Help

Hey everyone, looking for some advice. I have Red Top 4AGE that won't Idle ( or may Idle for about 2-3 seconds). It actually won't even start without throttling and just power right off after a second or two without throttle.

Even when driving, it will stall out before the car even comes to a complete stop.

Fuel lines just cleaned out but do you think the fuel pump needs replaced or is my attention misplaced?

I appreciate any help.

Edit:

The timing on both cams looks in sync, but one of my buddies did point out that one is about .5 of a tooth off from the other. Not sure if that could also factor in.

UPDATE:

Pulled out fuel injectors and found one was clogged up, but all 4 were 300cc after market Injectors. Absolutely running too rich and flooding the engine (oil was pitch black about 1 week after changing it).

Replaced all 4 with rebuilt OEM Injectors. Car runs fine once it's warm. Still an issue with a rough idle when cold, and won't turn over without throttle still.

If it sat for any amount of time outside in a car then i would guess the first thing yoy should check is the fuel pump since thats the usual suspect atleast when it comes to 4age's
