car starts hard when warmed up
Well my ta has gotten to the point that it starts fine when cold yet if you drive it for maybe 15-20 minutes it gets to where it won't start unless you really pump the gas, otherwise it runs fine any ideas?

Check the fuel pressure... these members are probably right, but you dont want to replace something and have that not be the problem... sh*t gets expensive when you fix a car that way

Mine also won't start when it gets warm unless you catch it just right with the throttle. I just put a new Aeromotive reg on it, same problem. I am thinking it just isn't getting enough spark or it it flooding itself...Leaky injecters? A motor would start just fine cold with too much gas,but not so well when it is warm.

Check your coil, at times when the coil gets warm if will not produce a sufficient amount of energy to give proper spark to the plugs, This happen to me with a blaster coil. Cold, start up fine, let it warm up and it would shut off, spin over but not start. Put the stock coil back on, drove it all day long..

Spacer mod? Is this to get it away from heat? My motor is crammed in the bay and it gets warm although the water temp stays around 180 and I am running it with the hood up in the driveway so it should dissipate heat, I would think. I am running the stock coil, but this sounds possible. I have checked for spark and it is there it just won't light it off, Not even with starter fluid. Could it be anything else like in the PCM telling it to not start? Any way to check without replacement?

Still having the floor it to start problem after it is warm. Not leaky injectors, not fuel pressure regulator 40-43.5psi, not coil or ICM (old ones tested good, but replaced them anyway and did the spacer mod), not plug wires, not vacuum leak, injectors are pulsing, and I have spark and full charge on batt, alt also charges at 14.6. New TPS as well, no codes other than a 1661 (I don't have a ses light installed). Idles kind of high.
