engine slow to start when warm

[karnoff]

i have a 1990 dodge spirit ES 3.0, now in the morning the car starts right up with no problem, but after i drive it somewhere and the engine is warm, it takes the engine a while to start, doesnt wanna turn over right away like it does in the morning, first thing. anyone know what the problem could be?

thanks

anyone?

Do you mean starter just clicking or longer crank time before it starts when it's hot, Sounds like the coolant sensor could be reading inaccurately or maybe the iac is carbonned up or sticking. Maybe a cam or crank sensor problem as well when the temperature gets too it. I suggest looking at the coolant temp readings with both the engine stone cold first thing in te morning and again when it's up to temperature. what's the mileage on your spirit?. keep me postted if you wish

its a longer crank time when the engine is warm....mileage is 160,000....i'll let ya know about the coolant readings, thanks for the response

You didnt run any aftermarket exhaust just under your starter did you? Sometimes they will get way too dang hot. Always start with the easy stuff, give it a tune up and see if it helps...don't forget the Fuel Filter.

If you have the older 3.0 with the bad valve guide problems, it could just be oil in the fuel? Does it smoke like a freight train when you start it?

Easy alternatives:
Clogged fuel filter, failing fuel pump or regulator (but not yet bad), bad rotor, cap wires.
That about covers the 3.0L

Slantsixness, long time no see!! Welcome back.

Have you thought about vapor locking?

To me it sounds like you might have a small bit of warpage or a vacum problem due to expanding when the motor heats up.

something else that is possible, coil. It is very common that when a coil goes bad it will act up when it is hot but will work fine when cold.
