Guys-Long time member, but infrequent poster. I fit the description given in the instructions for "first time users". I have almost all the issues of TDR from 18 on (lost issue 49), and have read quite a lot about hard start problems. I have not read any with exactly my symptoms. Before I embark on any repairs in this lousy weather (have to work outside) I thought I would check the pulse of the most knowledgible folks I know. Patient:1995 Ram 4X4 extended cab with Jacobs exhaust brake, and fuel filter relocation kit (there are other mods, but none related to the problem). Symptoms: after sitting for 3-4 days, the truck will start right up, run strong for about 3-4 seconds and then die. It will restart, but only after lots of cranking. It does not matter if it is warm outside or cold, so I do not think the fuel heater is in play. Once restarted, lots of white exhaust smoke. When smoothed out, it runs fine and if used daily I would not notice the problem. One other clue, the fuel filter "minder gauge" which came as part of the fuel filter relocation kit has been a continuing problem re slight weeping. I have changed the "O' rings several times ,once recently but cannot fix that issue. It may be related. If I were to do it again, I would not install that filter relocation kit. (IMHO,the cantelevered design makes it prone to vibration issues ). BTW, I replaced the lift pump, and solenoid in May of 2006. My current culprit list : 1)the return fuel line 2) the drain back valve in the pump. I would like to narrow don the list before repair. Any thoughts?
