    It sounds like a bad ignition switch. If the switch is providing power to the coil in the run position but not the start position, then the switch is getting power, just not directing it to the system during cranking. I'd replace the switch. I'm assuming the engine cranks over but does not fire up?

Poss bad earth, check ecu supply when then cranking. if not you need an oscilliscope to see what is up with signal on crank sensor, some vehicles power cable is so close the noise from it wipes the signal same as a bad starter it interfers with the signal, (noise is the magnetic fields)

Timing Dpecs for Toyota Supra 87 6 cylinder


1987 non-turbo: 10 deg Before Top Dead Center (BTDC) @700 rpm
1987 Turbo: 10 deg BTDC @650 rpm.

To set the timing, you will need to connect a jumper wire between terminals E1 and TE1 on the diagnostic terminal. This diagnostic terminal is located just aft of the engine compartment fuse box. It is a black plastic box marked "diagnostic" on the cover, which flips open to reveal the terminals inside. There is a diagram on the inside of the cover which explains the terminal positions. On the Turbo model, you need to remove the forward section of the engine cover to gain access to the number one spark plug wire.

It could be the throttle position sensor, this is a small electronic part that goes bad on pretty much every fuel-injected car eventually. I think it's located on the throttle body itself.
