figure my problem out.
here is whats going on be prepared...
92 Plymouth Acclaim 2.5l
when i first got the car.. the car would start and drive.. when it got hot it would sputter and die out.. let the car cool back down.. it would drive again.. but not for a long time.. maybe 10 min.
so i pulled codes. it through a 21 and 51.. 02 and 02 stuck in lean caused by map sensor. changed map sensor... no more codes.. drove the car same thing still happens.
next i changed out the entire throttle body, injector, FPR, ECM, and HEP. start the car up drives fine. go down the road starts doing exactly the same thing. i pull in autozone, buy an 02 figure thats got to be it.. the last thing. replace.. try to start the car.. and no go.. it would half way start.. but really rough idle then die.. eventually wont start at all. i figure pump is bad.. cant hear it when i turn it on. so get a new pump change it.
start the car... after a few trys... yay it runs.. but really really rough. and wont idle.. upper RPMs runs fine.. but i have to keep on the gas for it to run. pull the plugs.. black as the night. clean them up.. throw them back in and try to start it... nothing at all. so now it wont start period. check timing, and timing belt.. check compression , check spark.. check fuel.. everythign is fine. car will not start at all. im at my wits end.
so what is the problem?? if someone can figure whats going on and it fixes it.. i will send you $20 in the mail.
here are the thigns that have been changed ill specify new or used parts next to them.
map sensor (new)
throttle body, injector, FPR (used)
ECM (used)
02 sensor (new)
Fuel Pump (new)
HEP (used)
also the coil has been tested and checked out fine
all vaccum lines are hooked up .. to my knowledge. looking over it there are no vaccum lines loose.. and it doesnt sound like a vaccum leak anywhere when it did run.
i ahve disconnected the battery several times to clear the ECM
