1999 Caravan 3.3L flex-fuel engine. Van will start and run good when cold.(under 48-50 degrees). When van is warm, it will not crank(starter will not operate), can not hear fuel pump prime, service engine light on dash does not light. When I say warm, it is setting in the sun and about 50 deg. and no light or fuel pump. Any help will be welcome. Thanks, Graygeorge

 

Welcome to DF
Do get a bulb check when you turn the key on? And when its warm outside,try banging on the fuel tank with key on.Then listen for the fuel pump to come on.

 

All warning lights are on when key is on. Will do the tank bump tomorrow. Check it today when it was 65 deg. and it started up. Thanks for the info.

 

Changed ignition switch. Seems to be doing ok now.
