1989 Supra - 7mge

BadRiggins · 07-03-2015, 05:52 PM

I got a 1989 Supra now. I ended up with it because my friend borrowed money from me to buy the car, but couldn't/wouldn't pay me back. It had a blown head gasket when he got it, but it did start up and we heard it run. He did that work himself, I'm a little worried about that, haha. But he also did the egr/canister delete.. As well as he got rid of the 25719 tank "vacuum surge" with maybe a few other things.. I don't know if those can be taken out or not? And if not, will that stop the car from running/starting? Also, how can I disable and/or check if the alarm is stopping the car from starting?
Any help would really be appreciated a lot! I lost my job a couple of weeks ago and I really need this car running so I can go out and get another one, it's the closest one I have to running.

Well, unless you've got a JDM ecu or standalone engine management hardware you'll want to replace the EGR system... dumb to pull it in the first place thinking it'll somehow improve performance. Can't say about the vacuum surge, but it was there for a reason and it's not expensive so I'd plan on replacing it as well. Someone with more knowledge of the alarm system will have to chime in on checking it out.

Fair warning, a lot of owners start ripping, removing, and generally screwing up their Supras with their "repairs" and "modifications", usually with adverse consequences. You may have a hard time putting that one back in running order,
