Supra cranks but wont start

Ok I just tried pulling the EFI fuse and it did not work.
How would I test if the fuel pump is working? Would I have to remove the gas tank?
Also if it matter, my car was running great yesturday and this is the first problem I've ever had with it.

Pulling the EFI fuse does not fix cars. It clears fuel trim, which you can do on your own, clears stores diagnostic trouble codes (DTC's), and that is about it. If JJ has anything to add to that, then fine. Pull your EFI fuse after fixing, and after pulling codes. You do that to make sure it isn't an old code.
Based on many of these threads on this forum, the suggestion of pulling codes and looking for 14, and wiggling the CPS wires is a good place to start. So those were good suggestions.
CODE 12 RPM Signal
Diagnosis
No "NE" or "G" signal to ECU within 2 seconds after engine has been cranked.
Trouble Area
Distributor, or CPS, circuit
Distributor or CPS
Starter signal circuit
ECU
I dont know what any of this means though...:1zhelp:

Look at your CPS wires. It is the little black topped knob looking thing on the exhaust side of the engine, twords the front.

good deal
you might want to go ahead and fix it right. it will keep happening if you dont, and always at the worst time.
you can either buy new clips and pins from toyota to replace it all, you can hardwire it bypassing the clips, or make your own clip.
you can take it apart and bend the clips so they make bettery contact. but ive found that to only work for so long as well.
lastly, before you take anything apart take note of the wire colors. they dont match up to each other.
