Norm,

Even if it looks new, check the vacuum line to the FPR please. If that's not the problem, the fuel must be getting injected normally. So if the fuel is there, and there is spark at the plugs....hmmmm. Time to grasp at straws?

Maybe the timing belt shed some teeth? Or broke? Is there spark at all the plugs?
Look in the oil fill hole to see if the cam turns when cranking.

If it does, hand turn it to 0° TDC for #1 (Pull the plug and stick something in to verify that the piston is up) and see if the camshaft timing mark agrees.

If those things check out, it might be excessive fuel coupled with weak spark. The fuel part could be due to a bad Engine Coolant Temp (ECT) sensor telling the ECU it's below zero. The FAQ tells how to check ECT resistance from the ECU connector, I think.

That's all I have at the moment. Hope the experts get on board soon.
