Way too much gas on start.

Hey guys, I'm having a really hard time getting my car up and running. Just a little background. It's a 1988 Turbo II with a rebuilt engine (new rotor housings and compression is good). I had the car running at one point. It was a little stubborn to start, but it would catch after a few cranks and then idle fine.

For the last few weeks it won't start at all. The really scarry thing is that if I crank it a few times (no more than 20-30 seconds total) there will be gas dripping from the turbo area (and the spark plugs are dripping too when removed). It seems like there is way too much gas being injected while cranking. I've done the extended unflood (pull plugs and crank), but the engine just fills right up again. I pulled the UIM and jumpered the fuel pump relay and there doesn't seem to be a leaky injector (no fuel smell from intake runners). The BAC, BAC solenoid, and Air Supply Valve are still hooked up and seem to be working OK. One strange thing is that I get a ECU error code 6 while cranking. It looks like this is an error for the TPS. The error only comes up while cranking. If I turn the ign. to ON, no errors come up and I have verified the the TPS is set up correctly (with the two light method). Does the ECU look for the TPS while cranking? I know the system defaults to WOT if it doesn't see the TPS. Any other ideas or input? Thanks .

I put a push button in mine to ground the wire to the fuel pump resistor relay.

I push it while cranking to hold low voltage to the pump.

Oops, forgot a few details. I have a cut off switch for the fuel pump in the car, so I can turn the pump on and off while cranking (I'll crank with the pump on for a few seconds and then turn it off if it doesn't catch right away). The tach does bounce while cranking and I've confirmed that there is current in the plug wires with a timing light. It does sort of cough and hiccup while cranking like its trying to catch, and there is a little exhaust smoke coming out of the tail pipe,m but like I said, if I crank for more then a little while with the pump on it completely floods to the point of dripping.
