Okay iv been stuck on this problem for about a month im totally stump. Here is what i have changed in order. I changed my alternator and battery cause my alternator went out. My Torque Converter Shift Solenoid (Long snout solenoid, Mind you my car worked before i changed this solenoid)i didnt disconnect the shift cable i just moves it to the top of the pan.So once i changed that part my car all of a sudden wouldn't crank over. i bought a new fuel filter installed that new fuel pump new fuel relay and i used starter fluid to try and start it and nothing. Any thing will help i dont get why it started fine before i changed that one solenoid . some one please help any idea will help.

Let'* clean this up and verify everything here. You changed the alternator and battery, and the engine ran fine after that correct?

You changed the transmission TCSS and now the engine won't run or it won't turn over?

While the rest of us are pondering, go get the local newspaper, read the comics(this is to clear your mind) and go back and reverify every single thing you touched during the last task prior to the engine not running.

Is it cranking (turning over) but not starting, or not cranking? Your description is a little confusing.
