I have a 1993 Dodge Dakota with the 3.9 V-6 motor, with 90,000 miles on it. It randomly has time when it will not start. Sometimes it will start and " chug" a little then die. Usually if you crank on it, wait, crank on it some more, wait, crank on it again, it will eventually start. I have replaced the fuel pump, and seem to have good pressure, replaced the fuel filter, and have done a complete tune up. When the truck runs, it does seem to run slightly rough too. Any suggestions would be really appreciated before I just let the bank repo it and quit my job.
