Default A little problem..

This is what I got. The Engine along with everything else is in the car, and functioning. This is the problem. I go to start it, it back fires, sputters, won't barely even fire, and it floods.
This is what I did to check it over..
Everyone kept saying timing, so I took it all the way down to the OPTI, and turned the Crank until the Cam went to 9:00 position, which was #1 TDC, and placed the OPTI correctly on it(only 1 hole for it). The Timing Chain went on correctly(dots touching), so now there is no way the timing is messed up.
Then I re-set the lash on the Rockers since they now have oil in the Lifters, so that is good.
I checked all the plug wires, and they are in the correct spots.
The Starter works very well, no problems there.
It fires a couple of Cylinders, dies, fires a couple more, and it's done. That's with my foot to the floor. I think it's flooded, so I have to check that out.

I think it may be a Sensor somewhere, everything mechanical checks good, but if anyone has any input, throw it in..

Connectors correctly on the fuel injectors? As in, on the right ones?

Yup, they are right. We think it's a Sensor, or a setting in the Computer. The last time it ran it was mis-firing, and had that spun Bearing. The Computer could be in a safety mode.

Before you tore the engine down to R&R everything, did you ever diagnose what was causing the misfire?

I re-built with a new block, new Pistons and Rods, Rings, etc..
The old one was mis-firing cause the #4 Rod Bearing spun apart, shot metal in the Oil Pan, stopped the Oil Pump, causing the Main Bearings to spin. When that Rod Bearing went, it lost compression in that Cylinder, and mis-fired.

ouchy painful death!! You might check the readings on the coolant temp sensor. When they frag it will tell the pcm it -40F outside and it will flood the **** out of it.

So you think I might need a new one of them on the Front of the Water Pump there..
It is running rich, really rich. I am going to check Compression just to make sure.
