Not to be simplistic, but did you take the rotor off? If so check the continuity of the transfer circuit and if it can be put on backwards. Also, check the distributor cap for smashed or scorched contact posts,and no plug/dist wires have separated inside the insulation. If that is all good, check all ground straps and for loose screws in the distributor on the electronics and they are not worn to much or damaged. If nothing found during that, I would check for unplugged Engine monitoring sensors,if any don’t report properly it disconnects the ignition system and all of their wires run through the harness removed to access that coolant T you worked on. I don’t remember if that has a deadman rollover switch, but if so it might need reset.
I hope it helps, and good luck, if it doesn’t reply and I will try to get back.
