dodge caravan 88 hard start when engine hot

Hello to everyone here is my prob. 88 dodge caravan 3.0 engine just replaced head gaskets and did it ok, but now don't know what happened, is hard to start after it warms up, works ok when it cools down, (start right up at the first try). when reaches normal working temp then it gets hard but if i fully depress accelerator, then starts again (after cranking it for few more seconds ) it works normal after that.

Any help would be appreciated. thank's a lot.

Check the fuel pressure regulator, it may be bad and is leaking down pressure when the engine is hot causing it to be hard to start. The other possibility is bad fuel injectors that are leaking down. Change the FPR first as that is the cheapest and easiest to do.

Thanks a lot for the reply, i did check that and everything was just fine, it is fixed now, the problem was that didn't hook up a connector to the sensor next to the water outlet at the intake manifold and it has two wires coming out of there.


Hope this would help someone else.
