Perhaps you could check for fuel in the cylinder by installing the plug, pulling the coil wire, turning over for 5 or 10 secs and pulling the plug?

Anyway.. eeewww. Sorry to hear this is happening. I don't have any real 'remote' suggestions.

Yep, that should work. Since its not running, you probably don't even have to do that.. just pull the plug, wipe it dry, replace, crank it for 10 secs and pull again. It should be wet with fuel by then.

Ok, did that, spark plug was covered in gas.

update: got the car started after i aired out the cyl's and cleaned the plugs. I think it was just flooded. This brings up the obvious question of why it got flooded in the first place just sitting. I'm relatively certain that this happened because the injectors (which are upgraded 19lb injectors) are leaking a little bit of fuel when the car is off, i'm under the impression this can be a common problem.

Do you guys think this is likely? if so, what should i replace them with? These ones are HOGS on gas, i think people said 17.5lb ones were best? 4-prong something, better atomization i seem to recall jay saying?

Ouch, ya, 19# is pushing it anyway. I don't honestly think you'd see any gains what-so-ever over 17.5# injectors. I think the four pintle design are called Design 3, someone correct me if I'm wrong. You only see slight gains over stock injectors at super high RPM, like 6K+ anyway.

What year is your car? I think (you'd have to google) that the 1.3 Motronic have a flood clear mode, which is the gas pedal depressed to the WOT switch. That might be handy if it is flooded again.

Edit: i googled that, found nothing. Maybe I made that up in my head.

Do you think leaky injectors is likely though?

I'd only see slight gains over 17.5-> 19 or 14->17.5?

IMO, only slight gains of 14 to 17.5.. I don't think you'll see any with 19# unless you had a very freeflow intake, exhaust and chip to take advantage of it all.

Leaky injectors: I have no personal experience with them so anything I say would be conjecture. Just being honest.

To me, it seems more likely that the start up enrichment is just over the top with the amount of fuel from the 19#'ers, especially now that its getting colder. The ECU will dump a LOT of fuel when cold.

In any case, getting 17.5# flow matched and cleaned injectors would solve it if it's either case.

Ooo, i remember more now! If you suspect leaky injectors and can get your car to replicate the problem reliably (ie hard start after sitting for a while) you could:

1. attach a fuel pressure regulator and see if the pressure drops over hours / days
2. run the car, pull the fuel pump relay, car will die. then let it sit for a long period with no pressure, then reinstall relay and start. best to leave for a day. if it starts right away, then leaky injector. if it is still a hard start, then its something else.

^prolly gonna take you up on that bro!

Everlast-> I'm sure its leaky injectors. The car didn't start again today. Since it was raining and i'm bourgois, and i already had the fuel pump cover off, i disconnected the fuel pump, cranked it for a few seconds, it started, then died. plugged the pump back in, started right away, and drove off.

if i went to 14, should i go back to my stock AFM?

or with 17lb injectors could i keep the same tuning?

Just go back to 100% stock, and see if it cures the problem.
