I have a 98 Dodge Ram 1500 4X4, about 2 weeks ago my I loaned it out and they ran it out of gas. Now it won't stay running after it warms up. If you start it and its cold, it will hold the idle right at 600 RPMs. Once it warms up and you are driving it when you put your foot on the brake to slow down or stop the RPMs drop to 0 and it dies. I have taken the truck to two of the local mechanics and they are telling me the fuel filter is inside the fuel tank and is non-serviceable. I have never heard of such a thing. I took it into my normal mechanic and he ran a pressure test, it came back fine. He also hooked the truck up to the computer to see if any error codes would come up, nothing. Then I went down and bought some SEA FOAM and put that into the gas tank. The problem is still there. It's funny because if you bring the RPMs up to 2500 for a couple of seconds and then take your foot off the gas it will run just fine for a short time. I am afraid of doing any more damage. Any help would be appreciated.
