Slow starting. Spitting and sputtering too. Car starts up fine cold.
Sometimes when warm, say 20 minutes after turning it off, if you go and start it, it will crank and crank up to 5-8 seconds. Sometimes it will spit and sputter at under 500 RPM and require a little tap of the gas pedal to smooth it out. Really pissing me off plus it seems to be getting worse.
Injectors are new with less than 1K and yes it did it with the old injectors too. Fuel pump is original with 82K miles. Coil is a MSD red coil and appears good. ICM is grounded well. GM Opti has less than 4K miles. No codes.
Any sure fire fixes for this?

I have a similar kind of problem with a new motor, when it is cold the thing cranks right up without touching the gas but after warming up you have to give it a little touch of the pedal most of the time to get it running is this the same problem you are having?

Checked the fuel pressure, seems fine. I left the gauge on overnight and it did drop to about 10#. Turned the key to on and it shot right back up to 40#.
Is this normal? What about the FPR?
BTW I had a 94 Jeep Wrangler that did the exact same thing and replacing its fuel pump helped NONE.
