Wrangler won\'t start
First time posting, so please bear with me...
88 YJ Sahara, 4.2L, msd6, motorcraft distributor, MC2150 carb, TR TFI coil, cap, and rotor (I followed their post for parts), plugs gapped @ .050 (per TR & msd specs); computer, PVC, egr, & charcoal cannister connected - all else gone, though I still have the Duraspark wired (but not connected) in case of emergency.
Here's my problem. Has been running great since "upgrades" (last of which was over two years ago). Past three weeks though, I've been getting stranded b/c engine wouldn't turn over. Problem has been getting worse over time, and now Wrangler is sitting in my driveway, as I'm unable to get it to engage (at least it didn't leave me stranded in the middle of nowhere).
I checked the coil primary resistance (I believe/hope I did it correctly), and it's @ 0.8; timed @ 8btdc - ported vac to dist. Manifold vac @ 18" hg. Battery only two years old, and it is still holding a charge. Starter also seems to be doing its job.
There's fuel in the chamber (float level still correct) - and carb seems to be operating correctly.
I'm a little nervous about placing electrically-charged components (spark plugs, coil wires, etc.) close to metal to confirm spark, but I'll do it if one of y'all recommends that's the best route for me to take.
Any suggestions for a newbie would be greatly appreciated.
