Turn Key Twice to Start - Chapter 2

[Bluemill]

I had to wait to get a fuel pressure tester from Mid America to go to the next step of this diagnosis. Again, the engine cranks great but will not start on first turn of the key in the morning, but at lunch time it will, -most of the time. I have started to wait for the pressure to build by turning the ignition key, and then waiting until the warning chimes finish before turning the starter. On the first turn of the starter, it just will not start, even if I crank it 10-15 seconds. Second crank, it fires, regardless if I really crank it a lot the first time, or just a tiny tweak of the starter.

The pressure goes up to 58 psi with the key to ignition, no stater, then in about one minute will loose about two (2) psi. It continues to drop but it would appear to be a slower drop after the first minute. If the ignition is on or off, it doesn't matter, the pressure drops off at the same rate which is about a psi every 30 seconds.

I have already ready replaced the fuel filter with an OEM AC Delco filter towards fixing this issue.

I pulled my limited restriction dual cotton cone air intake system and replaced it with a stock paper filter. I broke down the MAF and cleaned the MAF filiments with denatured alcohol.

Does this still point to the rear fuel feed pipe? Or does this smell like something else?

Thanks,

the fuel pump runs for several seconds to pressurize the fuel rail and then shuts off till the engine starts. turn the key off and on several times before trying to start the engine as this will build up the fuel pressure.

I guess what's eating me is that this didn't do this before, it fired up quickly at first turn of the key, hot or cold, warm or cold weather, humidity differences, etc. It's a little strange. Over night, it always requires turning the starter over a little, then shut key off, try it again, it fires instantly.

This A.M. turned ignition to on 5 seconds on, then off, 5 seconds on, then off THREE times without cranking. Then I cranked. No ignition. Turn key again, BAM, it fires.

One hour and 45 minutes later after a meeting I hop into the car, turn the key, it fires right up. Now it's three hours later and I'll bet she will start easily - but who knows! It's acting like it's possessed or something.

Help!
