90 Eagle Talon Tsi fwd.

Randomly decides when it doesnt want to start. Have fuel pressure, spark, compression, timing marks are fine. I'm leaning towards coolant temp sensor? It is really random, it'll eventually start though after a while. Driving me nuts. Gonna try the coolant temp during lunch today.

 

Any codes?

 

obd1. was gonna get the code scanner tonight if this doesnt fix it.

 

Put a new coolant temp sensor on, old one was definetly messed up. Fixed all my exhaust leaks, well put a big16g on . but now my car wont start at all? it almost fired up for a second, then nothing. tried cranking for like 10 minutes straight and gave up and got a ride to work. would a bad o2 sensor cause a no start? i was also leaning towards bad maf?

 

car should still start with bad o2 sensor. double check if ur getting spark to all 4 cylinders,fuel pressure.

 

i figured the o2 wouldnt cause no start, i know its bad though. ill check the spark and fuel pressure tonight, i hope its the pump cause im ordering a walbro 255 and fpr lol

 

that still doesnt make sense though. when it does start it runs fine and as soon as its warm it'll start right back up no problem.
