Ive read alot of posts but i am still hunting and need some helpful ideas I have a 97
2.3l auto 4r44e this started out with PO7003 code i believe it said it was a stuck 2-3 solenoid and truck was missing 3 gear but i changed solenoid and di valve body upgrades when done it still did same thing, however thats not the problem so i run out of time to work on that problem so i parked it for a month when i went to start it it would not dtart so i checked spark it had spark between plug and plug wire im not sure how strong it is however i then checked fuel took bed off checked pump, it ran , then checked pressure on the rail it had 37 PSI, so then i shot ether in it and it ran a short time but i read ore and thought maybe crank positoning sensor which i ma currently changing now however i read more and am gettting confused and desperate im not well versed on all the electronics anymore im kinda old school, i am now freaking out thinking if this isnt it could it be cam sensor ? or even pcm or eec or ignition coil but it had spark and ran with ether but im starting to chase my tail here, so im trying to give the info i know for people better experienced to give some ideas or help if they would sorry this so long i was trying to set the scenario up accurately if any more info needed ill gladly supply it if i can, help would be appreciated, i guess im thinking pcm eec , or whatever theyre called now days and wondering if its not my problem from the beginning with trans and now this starting problem i dont know what kind of problems these sensor can cause. thanks in advance
