DAILY DRIVER w a/c!!

since theres a hobbs switch and cannot purge it into the motor at 3k in nuetral to test, i pull the vac. off the regulator and plug it. simple, now the fuel pressure thinks it at WOT which is 40lbs, therefore BYPASSING the hobbs switch and activating the system. Wellllllll, when i hold it at 3k and hit the kit it hits, noticably hard.Now the problem, when i make a pull ill grab it at 3500 in second gear and NOTHING. yes NOTHING??? i dont understand the problem! so i pulled the no2 solenoid out, took it apart, cleaned it throughly, put it back on the car. once again 900psi, NO LEAKS(and yes the nozzle it facing T/b) i tap the button..Boom it hits good. WOT not a damn thing.. what am i missing??? I also tryed it with the vaccum on the regulator, to see if maybe it wouldnt work bc of the hobbs switch(even tho i bypassed and it still didnt work)Thanks for the help guys

Have u tried jumping the hobbs switch?? maybe you have a fuel pressure problem under WOT(what pump is in it??), I wouldn't make a full pass bypassed, just check for actuation or maybe install a test gauge taped to the windshield to see if you have a pressure problem?? Maybe with the demand of the engine and the fuel solinoid its dropping below 35??...... HTH......A.Andy

I second the previous reply... need a fuel pressure gauge to see what is happening. I didnt see you post it so I am going to assume that you dont have one, but if you do (and again I dont think you do because you said you are holding it at 3000 rpm and activating the system) have a WOT switch, sometimes they move from the throttle arm hittng it and knocking ti back so it wont engage, I had a similar problem years ago and that is what my issue was.
