My 2002 Dodge ram 5.9 L has trouble starting sometimes. I turn the key and the starter wants to start the truck but its like nothing catches. If I keep trying for 15 min with a little starter fluid, it eventually gets going and doesn't have any more problems starting up for a while unless I leave it alone for a day or so. But sometimes even after a day or so, it starts up no problem. Any ideas out there?

Your describing a choke problem. At least you have determined that no fuel is the problem. Like a coolant sensor or fuel pump that is going and has too much resistance in the windings when cold. A fuel pressure test and scan may help. The engine may think it is already hot and needs less fuel.

Do you think its the regulator in the gas tank. Couldnt be the coils or the spark plugs right?

You mentioned that when you sprayed a volatile substance like starting fluid in the throttle body it wants to start. That is why I spoke of fuel punp. I would not be able to guess on someone else's truck. If it was my truck, I would install a fuel pressure guage(40 bucks at Autozone or auto parts store), and when it wouldn't start I could see if it had fuel pressure. Usually a coil pack or plugs fouled or bad will start but run terrible all the time. So I would use a scan tool and fuel guage to see whats up. A code is usually present on an electrical no-start. Also after it starts, the fuel pump has charging voltage(more electrical available) and that may be enough to get it going.
No, the way you described it, it didn't sound like a miss or no spark.
You have to check it when it is happening, fuel or spark may be missing, and all I know, is the words I am reading.
If I was there, I would check it for spark and fuel the way I spoke of. With 80,000 miles it could use a new fuel pump and plug
s also. I would like to tell you to get a ride and leave it with someone. To be sure. OK Joe The truck fuel pumps did fail quite a bit and that I know. When it won, t start for the 15 minutes, sniff or look fur gas in the part it is supposed to be.
