WONT START WHEN WARM

maybe leaky injectors when shut off. probably throwing a flooded code and cutting the fire to the plugs during cranking. just a guess.

I have the same problem on an '01 1500 5.9L 2WD. Have you found a solution?

Have 99 durrngo newfualpump new cranking sensor we'll run for 15 to 2o mins then won't start till cold again

i have 2002 dodge 1500 with a 4.7 and its doimg the same thing. Its also not wanting to excelarate. I change out the IAC, TPS, and O2 sensors also spark plugs and tested coils. Its idling a lot better but still rough to crank if its warm and acelaration sucks. Idk whats going on, im womdering if a bad catalatic convertor could be why it dont like to get up and go..any thoughts??

Could be about anything,wet coil wire,coil,pickup coil,gas in intake from leak of some kind ,shut out relay,I’m betting new coil and pickup coil and relay might help,I’m not that good a mechanic

Computer can go bad,then when cools works some,then it starts( I have the same prob, ,I’ll let y’all know when I find it

Im haveing the same problem 2001 dodge ram 5.9 4x4 think it my be aomething with the muffler couse mine didnt start doing it untill myhusband cut it off to make it sound load...leave it to a man lol

Power box next to battery .starter relay replaced solved problem

My pickup is a 2009 Dakota with 4.7 V8, automatic, 2 wheel drive. Once it cools down completely, starts, runs, has usual acceleration/power and I drove it about 110 miles. After killing I tried restarting it every 15 minutes for more than an hour......to no avail: won't start till completely cool again......

Coolant temp sensor

My issue was solved by replacing the coolant temp sensor and the harness that went to it. If your vehicle surges or wants to stall it's probably your fuel pump. If engine turns over and doesn't start at all may be your starter switch relay or fuel pump switch relay. battery box If it pulsates on starting (cold or warm) it's either carbon in your intake/throttle position sensor, or idle arm sensor (both result from age and carbon build up on sensors/body) If driving and surging occurs but no change in acceleration performance, MAP sensor.
