2001 toyota corolla turns over just fine and plugs are fairly new,but wont start even when using starting fluid. Aside from plugs is there any other reason it might not start?
Your Corolla is not getting fire to the coils, it has jumped time (but that is very unlikely because it has a timing chain). It has Coil-On-Plug, no distributor, so it could be the cam position sensor, the crankshaft position sensor (more likely than cam sensor) or you can try checking these fuses that I drew a red arrow to. If either one is blown it will not have spark. Click to size up.
I understand that since it won't start this is a problem to do, but it needs an OBDII scan. If you can get a scanner somehow the engine does not have to be running to fetch the stored DTC trouble codes, just key on.
