[]I have a 1996 dodge dakota sport pkup that starts good cold, once driven and it warms up and i switch it off and try to crank it right back up it might start up and it might not. when it doesn't start, i usually have to wait about 10 minutes then it will start. it's a 4 cyl 5spd fuel injected 2.5 liter. have had new plugs, new rotar buttom and fuel injectors cleaned - help what can it be?

 

I'm not sure but first when you replace the rotor you always want to replace the cap as well

Then how about the air filter, oil and filter, fuel filter, pcv valve, breather cap next?
While you gots the air filter ***'y off, use some carb + tb cleaner to clean out teh tb (throttle body OR carb).
Still got probs?
Spark plugs, spark plug wires (get 8mm's or better).

Beyond that it could be the fuel pump, but try the above first.

 

When it's not starting, determine if you have a spark at the plug. If so, check the fuel pressure at the rail with a tester (about $15). Go from there.

 

When my truck did that it was the coil. If you dont have spark or weak spark take the coil to autozone they can test it for you.
