Hello everyone, this is my first post so I hope it is in the correct place. I recentely purchased a 2.3L 2wd 92 ranger xlt. The engine over heats very bad and I am in the process of replacing the heater core, due to its leaking incredibly bad and being badly corroded. Anyway, I did a bypass and now when i try to start the engine, I get nothing. Could this be because I am an idiot and disconnected the ECM (I belive this is what it is called...the part on the heater return line that plugs into the T fitting?). I am fairly new to cars so please, any advice?

 

Its a PCM when disconnected you should wait 5-10 mins before starting. roll the key to the KOEO position if the light come on roll it to KOER if it doesn't start pull code because you'll have some. Troubleshoot and try again

 

the pcm on a 92 is on the drivers side, behind the tire. i don't think you unhooked it by messing with the heater hoses.

have you checked your battery?

 

yea i unhooked the coolant temp sensor. Turns out the problem was my battery was dead due to taking off the glove box and the light staying on all night. I replaced the battery, heater core, thermostat, and flushed the system. I am now happy to say that my ranger now runs perfect!!!! Sorry for the stupidity on my part. thanks for all your help!!

 

Glad to know it's working right! Cooling problems can be a real PITA!
