88 2.9 runs but doesn't start

can a map sensor be why my cylinders r getting flooded...replaced tps. iat, iac, fpr, and a tuneup. its so bad the only way to start it is to hit the inertia switch after a flood and then get it running and then reset the switch...and then watch money go out the tailpipe and the rest washing down my cyl. i dont feel all that bad bout the parts im replacing the b2 sat in a field for 4 years and its time to replace. ive been driving for 3 weeks and know this prob pops up oh i also did a forced upper intake cleaning....boy did that make a difference in throttle response

honestly it sound like your injectors are not closing all the way, possibly from having that of old fuel or having junk in the lines . Try a few bottles of injector cleaner. And change the fuel filter if you haven't. When does it flood? after running it?
