I have a sometimes starting problem. When it is warm or parked in the garage it always starts immediately but if it is left parked out side on a cold night it sometimes does not want to start. Battery is strong, spins engine fine. If it does not immediately fire it seems to flood, then it is a wait of several hours to a day or two and or a warmer day then it will immediately start and run fine. One thing I have noticed, I usually always let it warm for a few minutes before driving but the other day I took off as soon as it started and until it warmed up it seemed to lag and cut out. Once warmed up it ran fine.
I don't understand why it seems to flood, I thought injectors would keep that from happening. Seems to have plenty of fuel pressure. I have replaced the fuel pump, fuel filter, plugs, wires. Is it possible that the injectors are bad and that is why it sometimes doesn't immediately start and floods?

What was the fuel pressure when it wouldn't start? Does the fuel pressure bleed off quickly when the pump stops?
