96 Eldo ETC, 126,000 miles
EDIT: See Updated Post 5/5/15 for 'current'.
Issue:
-Just started happening within last week
-When sits overnight, the 'first start' is not starting on first effort (See edit:below. it just repeated with less than 12 hour sit time)
-Crank for a 'normal period + several more revolutions', nothing
-2nd time i turn it over, it normally fires and runs fine (sometimes has to go to third start, but typically 2nd effort starts it)
-Cranks fine from that point on, as well as throughout day, so long as i'm starting it such as drive to work, crank at lunch, crank to go home type timing.
-ONLY seems to be doing it when it is sitting 'overnight' (is inside, so no extreme temp issues)
-EDIT: It did it again after about a 2 hour 'sit', so I can no longer say it is only doing it over night.
-It is smooth at idle, be it cold or hot. it pulls strong with no misses or skips.
-Plugs and wires are probably 2000 miles old.
-Only code it has kicked was the 1350/1375 when I sat on the starter for an extended time. I cleared those and they haven't come back, when I just do the routine stated above.
first guess was 'leakdown' of fuel system
-48+/- psi on fuel pressure when Key on, Engine Off, so the fuel pump is charging (EDIT: It does 'drop off some' on fuel pressure gauge, but i don't know what is 'normal' and what is problematic.
-Have checked plugs on ICM
-Have check wiring (albeit, I'm not sure how this can be electrical, but it very well could be anything I suppose?)
-No sign of fuel at Fuel Pressure Regulator (and it was replaced about 2 years ago)
-I pulled injector rail and pressurized. no 'visible' sign of leaking injectors, but this would have to be a VERY small leak. Should I try to figure out how to pull and let it sit for a full overnight cycle somehow?
-I've done best i can to inspect fuel line fittings underhood and fuel filter and see no sign of any fuel or 'condensation'
I only get 'one shot' a day on my 'intial test', and I haven't tried the 'key on, engergize, key off, wait, key on energize, key off, key on, start, when overnight wait.
I'm considering getting a salvage ICM/coil pack and swapping, just to eliminate that as possible cause, but I don't want to just start throwing away money.
EDIT: I just swapped in a salvage fuel rail, FRP and all the injectors, just to eliminate THAT as possible cause. Will be a few hours before i can tell if it made any difference.
This was my late dad's car, in generally good condition so I was trying to keep it going for a while longer. Not at a throw away state by any means, just would like for it to start the way it is capable.
ANY OTHER IDEAS THAT I'M OBVIOUSLY OVERLOOKING?
Thanks, any other ideas?
