no fuel pressure
randomly my car has this "no start" problem. couple weeks ago i posted a similar thread and all responses leaned towards spark issues but with a new battery, new starter, new TFI, new solenoid, and new wires the car wont start this morning.
it actually fired right up and ran good for a few minutes then i could hear it hiccup. i snapped the throttle and watched the fuel psi drop. the psi was bouncing between 20 and 40 psi. i shut it off and released the remaining psi through the schrader valve. seemed like there was air pockets in the lines because it would mist, then spray, then mist, etc..
once it was relieved i began priming the pump. the distinct whine is there but no pressure. disconnected both feed lines and no fuel came out (not even a drop). i left the lines disconnected and bumped the key to see if fuel is making it to the lines which at this time i cannot see any.
crawled under the car and did a very thorough investigation of all lines and hoses. there are no visible kinks and like i mentioned earlier, the car was running fine briefly before this.
what the hell happend?

remember how i said it would start then die? well, i was creeping the car up hill into my garage by bumping the key several times. during one of the bumps it seemed to come to life and stayed running.
fuel psi is at 40 and there was no signs of pressure loss. i drove the car shortly after checking everything over and it runs beautiful.
my car may need an exorcism as im positive there is a demon living inside it.
