All that's left is the module, but, did you make sure you were getting 12 volts to the coil through the elec. connector?

Check the computer for corrosion, actually remove it from the passenger side panel in front of the door and seperate the ECU from the harness. There is a flaw in the ranger's drainage system that directs water down to a corrosion holding point near the antenna actually behind the body panel. This point sits directly over the computer. If the terminals of the computer are corroded then this is the problem with the fuel management system...maybe. It worked for me, i have a 92'. I swapped the computer from a junk yard and siliconed up the cracks after filling them in with "great stuff". Fired it up and it ran like a completely different truck.
