I have a friend who has a '93 caravan with the 3.3L engine. When he goes out to crank it for the first time it will crank just fine and when he drives it for a little while and tries to start it up again it will not start. If he lets it set for an hour or so then it will start back up and run fine until he shuts it off and tries to start it right back up. He has to let it set for an hr or so before it will start. Thanks for any help yall can give me...

 

When the problem happens check for spark. I'm just guessing a bad crank sensor or wires to the sensor.

 

I've seen fuel filters do this also.

 

Could be several things, could be a fuel pump relay, asd relay, bad sensor..First thing is first, when it wont start check for spark at spark plugs, check for fuel pressure, check injector pulse...do that and then let us know what is missing..

 

Will do guys!!! Thanks for all your replies..

 

Here is an update for yall.. The problem was the crank sensor. Changed it out and it starts back up every time now. He changed the fuel filter the next day and every thing is doing good for now.. Thanks for all the help guys.
