Bad fuel filter?
Bad fuel pump?
Did you by chance have the flexible fuel lines off in the engine compartment? Are the properly installed?

yes I have the tpi flex fuel lines, yes they are tight and it only does this when hot?
i have checked and tested everything else map,tps,injectors hot and cold new dizzy etc... just tested the fuel pressure today and got this ..???? fuel pump?? I did replace the pump with a china 255 of ebay but the pump sat for over a year and then went in... possibly a bad pump???

Bad pump or your fuel filter is plugged.
Are the fuel flex lines crossed in the engine compartment?
Grab a new pump from here http://www.racetronix.com/

I don't think one would reach because of the different length of the hoses and fuel and return line...
so this would be a bad pump??
I will change the filter and have my tank cleaned also I've dropped the tank twice and will not be doing it a third time lol 100 ain't bad for labor just gotta buy a pump
thanks for the quick response and also for taking the time to look at my post I appreciate it
