Resolved Offering $100 REWARD for solving my no start

[nytescion]

I'm now willing to paypal 100 bucks to whomever can figure out this no start problem I've been having. Issue I'm having is the car is very hard to start after it sits for a little bit. The longer I let it sit the harder it is to start. Even after cutting it off and trying to start it right back up takes 1 long (10 sec) crank. so far I've tried

-2 BRAND new coolant temp sensors (verified correct operation)
-BLT 30 40 and 50 psi (only running 30 psi)
-Spraying starter fluid into the the throttle body port for my boost gauge car starts right up first time
-ECU has no leaky caps, burns, fish smells or any funny business
-All battery connects are clean and tight (wrench or pliers)
-Bigger brand new battery (800cc amps)
-Fuel pump rewired to run in the ACC key position (after letting car sit with pump running still no start)
-Immediate fuel pressure when pump is activated
-Correct cam timing verified
*****I forgot to mention that if i enrichen my mainscale value on my maft and it does seem to help to get the car started BUT i have to adjust it back down cause I'll be running quite rich at idle if i don't.

One more thing i can think of is. This motor is out of my second talon tsi awd which was a 92. I did not have these problems with my 92. This DSM i have now is a 90. So only the things that were needed to change to work with a 90 ecu were changed. cam sensor, coil, throttle body thermo housing etc.

i don't know if it's possible but was the car running on the turbo timer after you finally got it started?

Explain what you mean here. I would say no, but not until i fully understand your question.

know that i read it again i don't even know how i came up with that question. but it was the mpi relay that was your problem?

95gsx - Vapor lock can occur in the fuel rail, without ambient temp being much of a factor.

Cold fuel(liquid) rushes into hot fuel rail and turns into a vapor/gas = extended crank.

With the OPs symptoms however, you're right it's unlikely.

no it was a loose wire coming off of my starter relay going to various sensors that i guess only get power when the car is cranking. after fixing that and a new sensor (I did both at the same time) It starts fine now.
