No Fuel Pressure

well I seemed to have found the problem, I sprayed the cam sensor off and it started right up, seems there was some oil on the sensor and it didn't detect any rotation.

Where is the cam sensor? Thanks

It's only on 7MGTE's, and it takes the place of the distributor. Since your supra's are N/A's, you won't have one

I have drained 7 gallons of 6 year old gas into two gas cans. Now what do I do with it? Safe way of disposal? What do you guys do with it?

Also I think I am getting no fuel to my engine. Drained the gas to see if that was it and possibly my plugs are fouled though I did check the number one and it sparked.

The gas I drained looked not to bad or dirty but certainly yellowed or tinged so I am hoping fresh gas and 4 new plugs might bring it back to life. It died suddenly during a test drive after 7 years of sitting. Timing belt is still working and I have spark so what can it be? Don't think Fuel filter could be clogged. Is there a place to disconnect the fuel line at the motor to see if it is pumping gas?

After cranking 20 seconds with pedal on the floor I pulled the #1 plug and it looked dry. It should have been wet.

I have a NA stock 86.5 5speed any suggestions would be appreciated. Thanks so much.

You can check to see if you're getting fuel to the fuel rail by putting a jumper wire in the diagnostic box between "FP" and "B+". That should cycle your fuel pump on constantly, if all the wiring for it is intact and there are no bad relays or fuses
