Rebuild starts then dies after like 3 seconds...

I got it started, after many times of hitting a problem, fixing it and moving on, i had it running for about 3 seconds, then it died. I have fuel, im pretty sure i have spark, although i don't know how powerful

Is it ported? I would play with the timing a bit just to get it to run for a while.

I would put a jumper in the fuel pump test plug in the engine compartment. That will keep the fuel pump on if the AFM is having problems.

it VERY MUCH sounds like the fuel lines are backwards. not that you're slow or anything, but you didnt mention that you checked that

- yes it is ported, didnt check the timing...will do that

-not a vac leak, removed rats nest, only 4 vac lines left and theyre all brand new and connected

-last time i did that the safc and evc didnt come on but when the key is on the gauges lit up automatically...i dont know why but i dont wanna do it again...i'm getting a ton of fuel anyways

-fuel lines WERE backwards, i fixed them...theyre good now

Check the fuel filter and make sure the injectors are clean, too.

Recently on my engine install it wouldn't start because the fuel lines were backwards thanks to the picture in the manual being wrong, then when it did start it did the same thing as yours, run for a few seconds then die no matter how much throttle I gave it, we re-stabbed the CAS and that fixed it.

Does it run at higher RPM's?
Sometimes you just need to bump up the idle just to get it stable.
Nevermind getting the timing nailed right now - if it crank and starts, that's a very good start.

s4 tps reads 100% when only at 1/3rd throttle. move the throttle while watching the tps and you will see why.

Ok that makes sense then... I was wondering if that would cause tuning issues, but I suppose not...

Do as the manual instructs, theres more than one dot on the shaft, but you want to align the upper dot to the matching mark.
