So I bought a 1986.5 Supra, and I have a few problems.

Well, the biggest is is that I'm about stupid when it comes to cars.

But other than that, let me start this off by saying I bought an '86.5 MKIII for $500. I figured it was a good enough deal, so I got it.

So on to the problem. It didn't have a battery, so it was replaced. Then came the fuses. And now it will not start, not even turn over. But the horn will (barely) honk and the lights will come on and go up and down.

I'm expecting it to be something so simple it's crazy, but could anyone possibly help?

Expect plenty more problems when you fix this one. Sorry but it is what it is. I figure now i was better off with car payments than this thing.

Fixing it is partly why I bought it. I mean, I have to start somewhere, and why not on a car I've wanted for ages?

That would be the first thing I would suspect.. then check the fuses on the deivers side kick panel.. and of course the ones under the hood... I kno u said u did this but do it again. Its real easy to miss one.. get back with me

It's a new battery, so does it still need it's voltage checked? Or does a volt meter do something completely different from what I think?

There's more on the driver's side? How many fuse boxes does the car have? Also, does it have any indication of the fuses it needs, in case some are missing? If not, could anyone provide a diagram or something?

And the one's under the hood are good. I've checked that two or three times since I replaced it. Only one's I'm kinda iffy about are the two big ones, which I was told I'd probably have to get from a dealer.

The ones on the drivers side kick panel has some main fuses which power the ignition and efi computer. check the link below and go forward to see all the fuses. And click page back to see location. Also bookmark this page it is the mkiii supra service repair manual. Or known as tsrm

Don't ever assume something new can't be bad. Especially a batt. But id check fuses first. And a volt meter just checks voltage. But they are very handy and necessary when troubleshooting

hey reverb try to find the post that talks about the alarm system, it happend to me before and that was it. GOOD JOB on having the supra , you will enjoy it. if i`m not mistaken on the bottom of the steering wheel colum theres a small black box with a lot of cables , i`m not sure but i believe that the blue and orage cable it`s the one you have to cut and ground the one out from the car not the box, but verify and hope that solves your problem. don`t let simple stuff ruin your project. Good luck . Q

500.00 is chumpchange.. you can part it out and make lots more.. hehe.

I am in same boat though.. wanted the car since new (actually wanted the MKII .. burgandy.. but ended up with the MKIII because of the targa and turbo). Definitely worth the coin in my opinion.

I believe if the alternator or starter wires are not connected properly (tightly and cleanly) this can cause the same issue as well. Also, the ground wire to the body should be attached firmly and cleanly. My 90 wouldnt turn over because the ground wire had actually popped out of the cable going to the battery.

Sometimes, pictures of the car/engine bay help us guess along with you.

Got my Supra as a fun ride, not for transportation. Have my 2009 Honda Civic EXL for basic transport. (no payments)
If you want a cheap ride, why don't you go out and buy a used Chev Cobalt? Get that great GM feeling!

kingison · 10-08-2010, 05:10 PM

yeah somehow i was mistaken the proverbial "jap car" was going to be reliable. If I wanted a "fun ride" I would have gone with an american muscle car. Instead I figured I would combine fun and reliability and have nothing but a ride I would only trust on short trips around town. Thumbs up!

kingison · 10-08-2010, 05:16 PM

That's okay I am preparing to re-list the car and not only profit, but give it to someone who wants to look under the hood every time before they drive it

Metaphysico · 10-08-2010, 05:20 PM

Its not that their not reliable it just that they are 20 or so years old. Buy a 20 year old honda and see how reliable it will be. Replace all the hoses, belts and a new water pump and it will be reliable as hell. I bought my 89 replaced all the hoses, t belt, thermostat, waterpump, metal head gasket and a few other small things and drove it for 5 years as a daily drive with out a single problem. Well until I ran it low on oil and spun a bearing. Even after the bearing started making noise I drove it another 3 months with a slight knock till it finally gave one day, then it got me 20 miles home knocking like hell, but it got me there. A full rebuild and a 5 speed swap and it has been just as reliable as ever. Point is its not reliable as is, replace all the old stuff that can go out and put a metal head gasket on it and your set.
