New Jeep owner, and this thread sounds as much like my problem as anything on the website. My '87 supposedly had a rebuilt engine ~75000 ago (202000 now, plus a few miles while my speedometer cable was broken...). The previous owner told me it had died on her twice, and she'd had the fuel line blown out. Well, it's started to die on me frequently, e.g., four or five times on my way to church, which is maybe 3 miles, although of course it's an intermittent problem. No warning before it dies, not that I've noticed. Only does it within a few miles of when I start. It's also intermittently very hard to start; starter turns over, takes maybe 20 or 30 sec for the engine to start sometimes. I've taken it to a local shop, who told me there was nothing wrong (because it didn't die for them, and probably started okay); I took it to the Jeep dealership, and that guy told me to get a Weber carb. So that's on order, and the Carter is on the floor in my garage.
However, as I like to double-check, I was reading this thread and noticed that the ignition coil sounds like a possible problem. The radiator was probably original and looks (from the cap) like it's rusted shut in places, and the engine overheats readily, so I'm also replacing the radiator. From what you guys are saying maybe the overheating has shot my ignition coil.
The plugs were somewhat deposit-covered and wide-gapped, so I replaced them, but as I say, the carb isn't here yet. Distributor cap looks immaculate, as do the wires (and the water pump, not that it matters to the dying problem). Checked resistance on the wires for the heck of it, and they seem fine.
So just to have my ducks in order in case the engine is still misbehaving when I put it back together and check the timing (sigh), there's:
CPS (camshaft pos. sensor--these are the same, right? or is this crankshaft PS?)
TPS (throttle pos. sensor--again, I'm not up on the acronyms...)
that I can still check. Any more ideas?
