92 civic with B18c GT35r turbo.

Starts great when cool (130F range and below), drives good, but when the engine is hot (170F range and above) and the car is shut off it will not restart until the engine cools again. The engine cranks strong but won't fire.

I have spark, fuel pressure at the FPR, and I have 12 volts at the injectors.

The car was recently tuned at Ill garage and this problem has been occuring since then. Not to bad mouth Ill garage, but they seemed to be in a hurry to get my car finished because it was so late (finished at 1 AM).

Possible the tuner missed something?

Bad burn on the chip?

Thanks in advance. Doug.

 

bump

 

do you have any CEL codes? It could be a coolant temp sensor issue or your main realy is getting hot and needs to be changed start there

 

no codes. i thought a main relay caused a no crank condition?

 

main realy issues will cause the car to not start due to it not activating the fuel pump

 

my fuel pump still primes though.

 

then its not the realy, does the car have an alarm system? check the coolant temperature sensor

 

i pulled apart the relay for ***** and giggles and the solders are not cracked. it clicks three times as it should during the different ignition cycles.

i checked the coolant temp sensor and it ohmed out at 1880 when it was roughly 75 degrees.
