I have a 1991 Dodge Ram 250. I got the truck a few months ago and after setting i school all day in 90 degree weather it would start, idle rough, then die.
A few weeks ago me and a buddy went muddin. I went in to eat and came out and fired right up. It was under 32 degrees that night. I went out the next morning and all it did was turn over. I put a new coil, plugs, wires, cap, and rotor on it. Started right up. It is currently just turning itself over. I found out that a relay in the engine compartment on the left fender was getting power but it wasnt sending any out. CAN SOMEONE PLEASE HELP ME OUT?

 

First thing that pops into my head from that information is the ASD relay. I know this is your first post, if we are to help you please be specific. Try to answer ALL questions that are asked. Which relay are you talking about as there are 2 to 4 relays in a row at that location depending on what systems are in your truck? How many connections are on that relay and how many wires go to it? When you first turn the key to on, not start, can you hear the fuel pump in the tank run briefly?

 

I have the 360 motor. There is two relays on the drivers side. I will have a post later with more info.
