HELP i think i fried something in my engine

[twiztid]

I switch that one out originally. Would it be possible that the igniter got fried. i believe its the little black box right above the fuse box.

Extremely doubtful, but if you've already replaced the fuse I indicated and things still don't work, then I guess anything's possible at this point. Before you buy a new ignitor, I'd find another MKIV Supra TT in town with a firendly owner that will allow you to swap his in to try it. I'm telling you though, it's more likely to be something VERY basic, since that fuse is supposed to blow (and that's the only thing that's supposed to happen) when you put the battery cables on backwards. After you replaced that fuse, did anything at all happen differently? For example, do any lights come on now, even if it still doesn't start? If possible, post a video online (via youtube, etc.) with you trying to start your Mkiv in its current state - be sure to get a closeup of the engine bay and the dash. It's tough to diagnose & troubleshoot problems like this remotely, but I'm willing if you are.

Well when we jump start it because the battery is dead the lights come on it cranks over and you can smell fuel. we did the self dianostic check awhile back and the code came up as fuel pump. i will run the code check again or i will have my brother do it on sunday. Its his car im just trying to help him out. I feel bad for the car because its sitting there collecting dust.

Unfortunately, no.

I pulled it out with the spark plug attached still so i can see if there is any spark. My brother cranked it over and i viewed the spark plug and there was not spark. So my guess no it has to be the igniter that is bad. Anybody know where i could get one for a good price.

Fwiw, I'd strongly recommend you get a brand-new one from Toyota. A few national 'yota dealers will sell parts to Supra owners at a discount, including Jeff Watson of Champion Toyota (800)327-2087, or Curt Aigner of Elmhurst Toyota at (800) 337-4358.

Have you tested if there's spark? Flip the coilpack sideways, put a couple of spare sparkplugs in it, ground the base of the plugs, and then turn it over.
