Hello, I'll start off by confirming that I have searched the threads and followed the guidance in the other posts about this problem to no avail, so here I am. 2002 GT 106,000 miles, no problems before storing and replaced plugs about 4,000 miles ago, but I did neglect to put fuel stabilizer in (I did't plan to store it for long but go deployed before I could take further measures). Anyways, it was stored with maybe a gallon of fuel for about 2 years, battery connected to a battery saver (Genesis G750). Outline of events below:
9 June 2017- connected battery, primed several times, attempted to start - no start
10 June 2017 - added 2 gallons of 91 octane, confirmed full battery charge, attempted to start - ran for several minutes but exhaust smelled very bad, rough idle, hesitation to increase RPM's. Shut off for 5 min, attempted to start - no start
24 June 2017 - attempted to start after priming several times - no start. Let it sit with ignition "ON" for several minutes - started and ran for 5 min and ran great, no bad smell no hesitation. Pressed Schrader valve before cranking - no fuel expelled; pressed Schrader valve while running - no fuel expelled
24 June 2017 - put in 5 gallons of 91 octane, Lucas fuel treatment, new oil & filter, replaced flimsy PCV hose that was collapsing on itself - attempted to start - no start. Tried repeating the steps that seemed to work before changing the oil and could not get it to start again; attempted start at least 10 times.
Items checked:
-PATS not triggered: THEFT light does not blink while cranking; tried lock & unlock with remote - no change
-Odometer blank while cranking
-Fuel pump hums when ignition turned to "ON"
-Battery full charge
-With ignition on, pressed Schreder valve - no fuel (also no fuel expelled when pressed while running)
-Removed Diablo Tune - no change
-Confirmed all fuses operational
-No trouble codes present
-Used rubber mallet to hit fuel tank while cranking - no change
Items not checked:
-Have not pulled injectors or plugs to confirm fuel or ignition - it ran several times so I didn't think that was a high likelihood
-Have not checked fuel rail pressure with external gauge - Predator Diablo turner read "75% FP" but "0psi FRP" with ignition "ON"
I've attached a spreadsheet of the other readouts from the Diablo, not sure if that will help diagnose the issue. Thanks in advance for any guidance.
