Will not start, flooding getting too much fuel

Based on this info, how do you know it is getting too much fuel? If you are getting too much fuel, have you checked the plugs to ensure they are not fouled? If they are fuel fouled then they will not ignite the mixture.

Let me know and we can go from there. Thanks

Do you have a scan tool that we can monitor the o2 sensor data? We need to see if they are reflecting the rich condition. This could be an injector issue but since it smooths out when the MAF is unplugged shows that it is able to pull the pulse width back and it responds.

Since this is happening, I am thinking the ECM is the issue or it is an input to the ECM so the ECM is reacting improperly and dumping too much fuel.

So at this point we need more info to go on. Hopefully you have a scan tool. If not, we may need to make a guess at it but let's start here. Thanks

What are the short term fuel trims doing? If this is running rich to foul the plugs they should be negative which means it sees a little amount of oxygen which means there is more fuel in the exhaust, which means it should be commanding the pulse widths to shorten. If the o2's are within spec and the plugs are fouling from fuel then that is an issue.
