I have an 88 gt, with the usual mods. I have my fuel pressure set at 39psi with the vacuum off. Now for the question- I installed the adjustable fuel pressure regulator and autometer fuel pressure guage. when i turn the key on the pressure goes up to 40, and maintains at idle, but as soon as i turn my car off the guage drops right to zero and sometimes after that if i leave the car off for like an hour or so, it will crank for a few seconds before it will finally start. but if i cycle the key a few times it will build the pressure and start right up. any help would be greatly appreciated. please email me at Skeezo83@hotmail.com thanks
