Car Won't Run.... Warm

[Two-Fortee]

If I leave my car for a day or so, go to start it, everything is fine. Idles great, then after about 2 minutes on idle it craps out. Then it won't start. Will keep turning over but wont fire up.

If I leave it for 10 minutes or so, and try and start it, it still won't. It will just keep turning over but almost seems like its out of gas or has no spark. Sometimes if I leave it for a little, like 30 minutes, it will start, barely, but very quickly bog right out.

Seems like as soon as the engine is just a little bit warm the car won't run at all.

ECU reads 55 (no codes), everything is hooked up properly, by the looks of it. Compression is 150 all accross. Battery is good.

Its such a weird problem, can anyone figure this out?

Thanks

soundds like you need to be checking out that coolant temp sensor.

i have the same problem. where abouts is this coolant temp sensor?

Yea try a coolant temp sensor, the one with the 2pins for the ECU not the single ground one for the temp gauge. Also a common problem with idleing either not warm or when it is warm is the Idle air control valve. They are a pretty easy fix. Just locate it, its round and has a 3/8 or so vacuum line running into it and out of it. you gotta mess with it and clean it because the bi-metal disc inside can get stuck and cause idle issues.

hey, i have a vauxhall viva with a ca18det in it that i've just bought, and it seems to be having the same kind of problem. when it starts cold it runs fine on 4, but then after 4 or 5 minutes and it gets warm, it drops down to 3 cylinders. i've unplugged the coils while it's running and it seems to be a different cylinder every time, so i'm pretty sure it's not the coils. it was running fine when i bought it about 4 weeks ago, but in the last week it's started doing this. i don't really know much about this sort of stuff so any help would be greatly appreciated. Thanks.
