Fuel presure goes to 60psi. then no psi. 87 turbo
 

I am new to supras. I have alot of other cars but i am unsure on what the problem is in the supra. This is the senerio. The car starts and runs for about 40seconds. Then it runs out of fuel and dies. if you push the throttle the fuel pressure builds for a sec then looses it all again. Do you guys have a way i could test the fuel pump. It acts as if it is a relay.

The fuel pump relay should be on the passenger side (assuming LHD) fender well attached to the fuel pump resistor pack. The resistor pack is the aluminum finned module.

the plug wasnt in all the way :dance::dance:.
But now at 4,000 rpm the engine dies as if it looses fuel pressure.

When was the last time the fuel filter was replaced? It is a pain to get to, because it is under the car over the rear differential. But, your not getting the proper fuel delivery.I'd try the fuel filter next.
