2000 caravan 3.3 50k miles. has hard hot start issue. cranks fine and will not fire. when it does start, it stumbles. i am thinking temp sensor. IAT or maybe coolant temp sensor? cleaned throttle bore but have not driven since to see if that helps. worked on other cars.

RE: hard hot start

1. Any trouble codes set?

2. Measure the resistance of all ignition leads. Any of these out of bounds? My experience with this engine found that the OEM leads can increase in resistance enough when hot to cause weak, or ignition misfire. The engine, with cold leads started ok, but would misfire under load after the leads got hot.
