Why does the Cold motor start longer than the warm motor?

Reason being, with bleeding injectors, the longer they sit, the more fuel gets dumped into the cylinder (until all the pressure is bled off). The OP would see the issue more on the cold side than on the warm. Also, there shouldn’t be any “gaps to fire” in the injectors. If there are, they wouldn’t fire at all.

What causes fuel pressure to drop on a warm start?

The pintles can wear out and allow fuel to bleed off into the cylinder thus dropping pressure. This excess fuel in the cylinder can cause a flooding condition on warm start which the PCM doesn’t know how to deal with since it expects fuel pressure to be there and thus won’t immediately demand anything from the fuel pump.

Why does my Car start cold instead of warm?

If the injectors were bleeding off fuel as you suggest, there’d be more of a problem with cold starts then warm. Reason being, with bleeding injectors, the longer they sit, the more fuel gets dumped into the cylinder (until all the pressure is bled off).
