SOURCE: 1994 Toyota Corolla hard to start when warm

does it have a cold start injector seperate from the other injectors usually on the upper intake somewhere with a fuel line going to it

Sounds like a faulty cold start assistor. On top of the engine you will find an aluminium housing with four things that look like glow plugs screwed into it. These 'glow plugs' are only available complete with the housing fron Vauxhall. Approx £70 +
Airbag light is probably a fault with the seatbelt pretensioner.
Check the wiring under the seats for damage or perhaps the plugs have pulled apart.

Check glow plug relay switch, located under your battery tray

If there is a problem with the crankshaft sensor then when you attempt to start it the ecm cannot confirm when number one cylinder is on top-dead-center thus not activate the 'open loop' part of the engine controller. I think the reason that it was running fine then would not start was because the only time the crankshaft sensor is used is when starting, not after while in closed loop.

Possibly is your glow plugs, best to change then all yourself if you can with just a ring spanner and a deep seated socket. Also not enough power in battery to heat plugs up in first place can be the cause. When deisels have been started a few mins, usualy start without waiting for glow plug to go out.
