The car sat for a year and a half before now, it started right up after sitting for a year and now ive got the fore mentioned problem.

The intake boot was loose on the filter box, i noticed this afterwards when removing the system for a CAI.

Any help or suggestions at all would be greatly appreciated.

Thanks,
Charlie
if you are not hearing the FP prime in the koeo mode briefly , then grab a test light and whil you have someone pulse the key and or crank check for power and ground back at the FP connector, if you have both and no noise/prime from the pump, which will be evident by seeing no pressure develop on a fp gauge if you have one hooked up to the test port.....key here is have test equipment to verify the source of the prob
