supra wont turn over
 

i have a 87 7mgte and i recently whent to start it and it fired up fine wouldent stay running with out the pedle pressed down a little bit then it died as soon as i let off the throtle in the drive way and then i got it running and yesterday it wouldent crank over at all so i tryed boosting it and nothing everything else comes on but it wont crank over after wile it did but tonight same thing but it would not turn over at all just woundering what this might be

If the car doesn't turn over even when attempting to be boosted by another vehicle than its the starter. when they wear out they will sometime still work on occasion. but you need a new one. doesn't explain you idle problem though

annyother possibilties

Just because it fails to start when boosted doesn't necessarily mean it is the starter. You could have corrosion on the battery cables, especially if you have metal ( as opposed to lead ) battery terminals. metal ones don't have to corrode near as much to impede the function of the starter. if you ahve metal battery terminals they usually have 2 bolts next to where the wire connects that hold the wire into the terminal, take that piece off and check the connection there between the bare wire and terminal. If in doubt, clean it.
The starters on these cars are pretty bad ass, they don't fail very often. ( not saying they don't fail at all) I would give every connection some major scrutiny before i get under there to remove that starter cause that is a pain.
AS far as not staying running, i would check the idle circuit on the tps as well as the connection to AFM. You can find information on how to do that http://www.forum.mkiiisupra.net/show...&highlight=TPS

i just dont understand becuase one time it started fine then 10 min later it was acting up and wouldent turn over

When I got my turbo supra, the car had been driving all day so, I test drove it around for about an hour and then pulled up to the owners house, hopped out gave the dude the money, did the title stuff and went back out to the car hopped in, turned the key, CLICK! nothing, jumped it, CLICK! nothing. Got my friend to tow the car home, looked at where the starter was and said FU*% THAT. I took the battery to the store to have it tested, tested good. Went home looked at the battery cables, they looked good, but I decided to take them apart anyway, cleaned the inside of the terminal where it actually touches the bare wire, and started right away. Just though I would share that with you

if it's not the battery terminals. Which i think might be a bit of a long shot. I replaced the starter on mine in a couple hours. Not a big deal, you just have to start.

I have a question for you guys I have a 7m ge and the car wont stay running it will turn over every time but wont stay running I saw the post about the afm sensor and was wondering were that is and if there is anything else that can cause this symptom

check your codes.. if it comes back code 31 then yea, its most likely a wire going to you afm. There is a wire in there that tells the engine how much fuel to give it when cold.. explains your running issue dosnt it.

I checked the codes and it poped 41 51 so I got a new tps but its still poping 41 and still haveing the same issue
