Fuel flooding the intake???
He guys, I have a 1991 3.1l , Im in the middle of a turbo project and something very strange happened, the car yesterday wouldn't start and when I removed the intake and looked into the throttle body, fuel came almost pouring out. I do have an external fuel pump to increase fuel pressure, did I somehow flood the entire upper plentum to have fuel comming out of the throttle body? How did that happen? And what broke?

It's a standard t3, however I dont believe the problem is the turbo, the turbo itself doesn't have anything to do with the fuel delivery as far as I know, something is happening in the manifold, it's like the injectors are continuously firing completly filling the entire pletum.

I,ve seen a tbi injector short out, stuck open. In my case the the driver in the computer then failed. Had to replace injectors & computer. Remember also tbi injectors run on fairly low pressure. If your extra pump is compounding the pressure of the stock pump it may be possible to force fuel past the pintle of the injector. HTH Mark

If the charcoal cannister fill swith fuel it will then dump raw fuel into the plenum. Although this is usually caused by switching the hoses around at the tank. Pull hose from cannistoer at TB, and see if fuel pours out.
