HELPP!! KA-T wont start

Hey so i just finished installing my turbo setup, and go to start it and it cranks but wont start. It is getting fuel because the spark plugs have gas on them, but I dont think its getting spark. I have reset the timing to tdc, and still nothing, then tried in 180 degrees over, and nothing. what can it be?

Fouled out plugs, bad coil, bad distributor. It has to have good spark otherwise you'll just keep flooding the cylinders.

well the car ran fine before i put the kit in, i dont see how distributor would go bad from sitting for a week, and the plugs would be fouled

If the car ran fine then why'd you reset timing?
Is this a S13 or S14?

car is an s14, setup is t25, n60 maf, 370cc injectors, fmic, and stock ecu right now just because im waiting for a obd2 obd1 conversion to run my tuned ecu. anyways i had to reset timing because i took off the distributor to put in the manifold because im dumb. what else could it be?

alright so got the car started after reseting the timing again for the 100th time, and now it runs super rich and cant hold an idle. im gunna put my tuned ecu in tomorrow, but as for now what can it be doing to cause it to idle poorly? and i think its rich right now because the infectors flooded because i pumped it to try to start it ( i know u shouldnt pump fuel injected cars )

okay so yesterday the car wouldnt start, then today i put in the tuned ecu and it started right up, but started bogging again, but revs up fine past like 2.5k. but there is smoke coming from the turbo manifold, not sure where tho, the turbo was just rebuilt and has 0 miles on it if that helps. and the engine shakes

who rebuilt the turbo? smoke can be from burning oil on the turbo/manifold. Now as far as running like shit, are the parts you bought new? injectors, plugs etc

i had a receipt for it being rebuilt, but it had no shaft play at all, and injectors were used i think, came with the car. plug wires are new, but it cant be them because my car ran fine before the turbo went in. ideas about turbo not spooling? the wastegate actuator doesnt move when i step on the throttle. i ran the wastegate vacuum to the hotpipe, so not sure whats going on. need to get my car running asap

Well i would check voltage and resistance throughout your ignition system and see how they compare to oem specs.

Can you be more specific as in not spooling? Like the turbine is stuck? at idle? throughout all RPMs?

like not spooling throughout all rpms, when revving. if the wastegate was stuck would it still spool? the bov is still engaging, so im confused

could be cam timing if you messed with the timing chain

OR

it could be that your dist. is sparking at exhaust TDC rather than compression TDC (it will still show up on the crank pulley as TDC)

didnt mess with timing chain, and for TDC would that cause the bogging? im gunna check the injectors, because thats what it was last time i had this problem pre-turbo. and what about the wastegate being stuck? should i be able to pull the actuator arm to open the wastegate?

now the car will not rev past 1.5k rpms, and found out #2 injector is bad, causing bogging. and i pulled on the actuator arm and it opens the wastegate, so i dont think its stuck open. still dont know why its not spooling
