Howdy yall, I bought me a 97 supercab 2.3 5 speed the other day. I runs great.... when it actually starts... Its gonna need a new flywheel and possibly a starter but thats for another story.
So sometimes it will fire right up, and sometimes it takes forever! Hot or cold, doesn't matter. New ECT, new plugs/wires, good fuel pressure. Timing is 10 BTDC. My dad and I believe it is a problem with wiring to the primary coil When cranking it backfires through the intake. . If the front coil is unplugged, the thing runs like crap, however with the back coil unplugged and the front coil plugged in, barely noticeable change in the way it runs. We swapped them around to no change in the way it starts. We read that the front one doesn't start working until 400 RPM, so we think this explains the hard starting yet great running. Checked grounds, and checked resistance between coil plug and eec connector. One prong had some resistance but the other 2 did not. Do you guys have any suggestions for what the problem is?
