ok to start i have a s14 with a s13 redtop sr set up

had it for quite a while and never had a problem till the iac valve started going bad. so i took the intake manifold off and cleaned it,had a hard time with the coolant feed/drain that goes to the iac valve so i just blocked it off.The car started up fine and drove with not one issue, after turning the car off i changed and went to leave but the car was not wanting to start. it will turn over just not start, after messing with it to find the issue ive realized the issue, its getting flooded with fuel upon starting. so i got another iac valve to see if that was the issue, sure enough it starts up perfect for the test drive but after that it once again is flooding with fuel upon starting. thats when the coolant lines came to mind, i figured this is only happening when the car is warmed up and i let the car cool down over night and tested my theory, sure enough the car fired right up.I took the manifold off and connected the coolant lines and for the first start up it worked, after i let it warm up i turned the car off to try to start it but it still is being flooded with fuel......... im lost, ive checked the injectors, injector rings, pulses to injectors....i cant seem to figure this out.

if anyone know what this is or has any info please help

 

Coolant temp sensor

The Ecu thinks it is trying to start a cold engine so it is dumping too much fuel.

It could be coincidence but chances are you damaged the plug when you took it apart and re installed

 

hmm ill check that in the morning !!thank you so much !
