'90 4A-FE Problems. Help, por favor?

[85NAPSZ]

Since my 720 has been in the shop I've been driving a 1990 Toyota Corolla. Some nights when I push it a little harder than usual then park it, sometimes it won't crank and I need to have someone jump me off? The battery and alternator are fine, and almost brand new. Any ideas as to why this is happening?

Clean your battery terminals and dont drive your Corolla like an ***hole on public roads.

My battery terminals are spotless, and I don't drive like an ***hole. Not only is it dumb, it looks even dumber in a '90 Corolla.

Check your hot line to your battery from your alternator then.

Will do. Thanks.

More likely wiring from battery to starter or the starter itself. When stuff gets hot resistance in the wiring and conductors within the starter itself goes up and it doesn't work any more. Make sure all heat shields are in place and wiring is properly routed. How comfortable are you under the hood? And do you have a multimeter?

Well, I have a multimeter but I'm not as comfortable under the hood as I'd like to be, mostly because I'm only 17. Paint and body is my squeeze. But, my dad helps out a lot and he's pretty good under the hood.
