are there any nosies coming from the engine such as clicks and what not? when you start it have the alternator checked most parts stores will do this for free. if the alt checks out fine have the started checked. the problem could even be corrosion on the battery posts and terminals. the stalling leads me to believe it's alt. related though. you should first make sure the connections to the already mentioned parts are free of corrosion and secure then have the mentioned parts tested.

Run an ecu diagnostic and get back to us. If the codes are clear then start checking electrical issues such as grounding, alternator, and battery.

idk where the implication was made that you are stupid. i do know however that you have yet to answer my original question. just fyi if the car can be push started and stays on the alt can still be the problem just as a number of other things. the obd I 240s don't need a special tool to check for codes so that would be a good place to start.

We are all equal here bro, Ramos is just being direct and to the point. He isn't trying to call you an idiot. He's just trying to help.

no grinding clicks or noises of any sort. how do i check the ecu. sorry about that last post just frustrated about the car i checked everthing i could think of can't figure it out on my own and i'm not good at asking for help. some of my friends have been saying something about a crank position sensor could that be it.

first download the fsm in it you'll find the answers to your question about the ecu.
https://www.s-chassis.com/forums/how-tos-installations-48/free-downloadable-factory-service-manuals-fsm-34805/

the absence of any noses tells me that it's probably the battery or starter. you say it did start at one point but it would stall so i'm thinking your battery is dead because the alternator is no longer functional. once again i'm just coming up with the best possible conclusion based on the information you provided.

you should probably take off the alt and stater and have them tested along with the battery. most parts stores will do this for free.

i don't think it's ecu related directly but like i said, we can be guessing here for a while unless you check for codes. i could tell you to test the inhibitor switch, coil, injecters,maf....... and so on but like i said it's a guess.
