Help - Howell TBI Install, 258 with MSD Ignition
I need help. I have an '87 YJ with a 258. My friend and I tried installing a Howell TBI kit on it today. I have done the TR upgrade and have an MSD 6A. The folks at howell forgot to include the MSD Filter so I tried to revert back to the Dura Spark ignition just to get it going. The issue we think we had was getting spark. We seemed to have been getting fuel and the fuel pump seemed to be working. The instructions were unclear as to which side of the TBI the fuel line goes into and which side the return line goes into. Also, we kept the orange and purple intertwined wires and hooked the purple into the jumper wire that we put into the Dura Spark connector. The question we had was where to connect the orange wire. I do not have an orange wire on my Dura Spark. We tried the green and black wire, but the engine did not turn over. Are we missing something? I hope once I get the MSD filter from Howell this will solve the issue, but does anyone have any insights? Thanks in advance.
