i did a conversion 2 years ago with my 98 gt and a 97 gtp motor . Now my motor is flooding to death i check fuel presure 50 turn key and 45 on crank no big pressure drop with key off . i have headers and an intense psm and im starting to think my psm has issues. any one have any input in fixs car is loading up so bad im smoking at red light died once and have back fired once . im haveing a gm mechanic take a look but im worried . all vacuum lines are correct and ive replaced mafs
 


It's not likely that the PCM is messing up.

Fuel pressure regulator might be dumping fuel into the vacuum line. MAF may be bad, the O2 could be bad, an injector might be stuck open.
 
i have replace MAF is there a specific vacuum line should i check and if he cant figure it out i have some old injectors ill throw in i appreciate the quick reply bill
 
The FPR is on the front left of the fuel rail. pull that connection and sniff the vac line. You'll know w/o a doubt if it's full of fuel. Doubtful..but possible.

He'll figure it out if he's any good. Dumping fuel is relatively easy to figure out.
