Look at the fuel regulator hose by removing it to see if there is any signs of gas in the hose.
If yes, the regulator diaphram is allowing gas to flow direct into the intake and flood the engine.
Otherwise, the injectors are pulsed at cranking time. If igniton fails the engine will load up with gas.
Normally to clear it, floor the throttle to shut off fuel injection and crank a mimute to so to clear the cylinders. If there is ignition it should attempt to fire when it clears enough.
Good luck.

It does try to fire like that. I even tried spraying fuel up the throttlebody and it also tried to start like that. Thinking it my b in the Ecm. Got a new one in gonna take it to for to get it programmed then they can tell me if there was something wrong with my old one. Hopefully there isnt and it is something small.

Your at a point that it needs to be looked at with a scanner full time to see what happens when it dies.
The scanner should trap the conditions at time of failure and offer a lead as to what the failure involved.
It's hard to help much more from afar behind a key board.
I did this for 30+ years from drawings and telephone, helping techs who had the same info to look at, out of a jam with other types of very large systems, so that is what I try to do here as the only way I might be of assistance.
Only difference here is the owners usually are not techs so I have to steer them in the most basic ways by suggestion and example. Sometime it works sometime not.
The help depends very greatly on accurate discription and honest feedback otherwise it's the old saying 'garbage in garbage out' result.
Good luck to you.

allen, if it's a flooding condition why would you spray even more fuel through the throttle body?
If the plugs are wet with fuel they won't fire the gas.
You have to establish whether or not this is the case so you know what your chasing.
Why pay out for an ECM before you know what's going on? It's just expensive guessing.
If he motor fires at all it's not the ECM.
