aero 11104 pt# im using 2 100 micron filters.cant imagine them beeing that dirty already,but i guess its poss right.seems like thats what everyone thinks,itll hit and miss under accellaration.like a bad plug or wire.thinking of taking off the speed pump controller.Originally Posted by TurboMic

Could be a bad ground or not enough power.

Maybe a loose or faulty ground connection on your speed pump controller or electric fuel pump. The power he is talking about is in the wires. You may have too small of diameter wire to supply voltage to either of the two pumps...

The voltage could be dropping below 12 volts which will cause all kinds of problems

ok i checked the filter and indeed it was full of all kinds of sht.somehow ithe guy that changed the fuel pum when it was intank left behind the shrink tube from wires,black tape,silicone,and some gel ,alll i can say is thank god for that 100 micron filter,cleaned it spotless,reinstalled 2 nd 1 in line was totally clean,put back together.i raised the f/p while i was under there to 60 psi for the 42 lb injectors only a few psi.started back up 80 percent better .i still have a little skip and ive gone lean from before filter cleaning,,allens tune was super rich,but the pcm kicked it lean,should i reinstall to richen or am i really still lean,the weird thing is it was rich for a couple hours.so im asssuming the pcm kicked it lean.and the fp gauge raised very slowly when i turn on the key,it used to fly up then drop till i started it ,i have a bypass regulator on it .weird it goes up slow then when i start it it flies up normal.any explanations for slow rise?and because its only 80 % beter i still have a little skip,what should be my next step?i thought my injectors might have gotten dirty or clogged when i saw that mess in the filter,but filter 2 was spotless,so i dont think the inj are clogged any sugg of what now.thanks ahead.i love this forum everyone is there for ya for opinions.sometimes you dont think of the littlelest things.thanks guys

Maybe you have a large pocket of air in the lines.

How are u running 15psi with 42lb injectors??
How much horsepower are you running? Where is the pump located(distance from tank)? What size lines in and out of the tank to the pump and from the pump to the engine? Filter arrangement? 1 before the pump and one after? Where is the fuel pressure regulator located(distance from fuel rail)? Are the fuel rails aftermarket or stock? Do you have a tuning program, hptuners, etc? If you do post up the log file and I will have a look. RC
