Difficult to start when warm

[ctm78]

My '94 MTX w/ 125K starts up just fine when cold, but when it's warm I have 5-10 seconds of cranking before the engine actually starts.

Any ideas?

It is near impossible to help diagnose your hard starts with the little to no information provided. To even try would be unfair to your wallet because all anyone could do is throw blind speculation your way.
It could be sensor related...
It could be ground related...
It could be fuel related...
Do you have a check engine light?

No CE light.

CPS is new, fuel filter and pump are relatively new (less than 1 yr). Still have to do 120K on the plugs/wires. Which other sensors could cause this?

She usually starts right up after one crank when cold, but when warm there's additional cranking. Not a huge issue, she always starts. . .I'm just wondering why all the cranking when she's warm.

Fuel pressure regulator?

Running the codes might help.
