[amped12345]

Hey Guys I have 89 Toyota Supra with a Rebuilt Cressedia Engine 7MGE . I put it together set the timing accordingly with the distributor and all the wonderful stuff . and i cant get the car to fire up, it starts gets to 1000rpm then dies instantly i cant even keep it going with the gas peddle pressed. and i noticed my fuel pump just stopped working after two days of attempting to start it even when trying to jump it via the diagnostics panel with the key in the on position, or when i push the flap inside the AFM. any reason it just randomly died? also there is a single white wire with a gray plug over by the intake manifold it has no where to plug into , its not for the fuel injectors and it doesn't reach very far.

Picture of plug?

If you jump fp and b+ in the diag box and the pump does not come on its bad.

That's the plug for the knock sensor. Sensor is on the side of the block under the intake manifold next to the acis vacumm tank.
