i just completed an engine overhaul on my 91 Justy. i have adjusted the throttle-sensor and replaced the fuel pump. when i start the car cold, car starts and runs well. but when engine has been warmed up, it is difficult to start the car again unless i cool the car down. can someone tell me whats wrong and how i can solve this problem.

 

thanks

what does it do when it wont start?

I'd guess the coolant temperature sensor (CTS) is bad. No idea where it's located on a justy though.

 

Would be cheapest to replace from a junkyard; I believe dealers want big $$$ for them.

nothing.. i have to sit and wait till the engine cools before i can started up again.

I have seen the coil cause symptoms like that. See if it is getting a good strong spark,at the plug wire while trying to restart it, when hot.

Update ..... thanks a lot for your info. you point out problem like magic. WHAT A WISE! I put a new CTS in this morning, Justy starting well on any temperature and running well. Thanks again.
