79 won't start after cold couple of days

[colofan]

My 79 Fj40 turns over and yet no go. It was running just 3 days ago just fine. I have replaced the coil about 6 months ago and about three weeks ago I had to replace the bottom casting holding the thermostat. Frozen bolts was the problem. Anyway I ended up getting a 1978 bottom housing which does not have the space for the smog valves so I disconnected them and everything has been working. I just removed the hoses to the BVSV and went on my merry way.

Well I am not sure now if I have an electrical problem or if not having the vacumm lines connected is causing me my problems. I have purchased a new distributor cap and rotor since I don't know if that has ever been done or not.

Ideas?

might be fuel related if not electrical.check sparkplug for spark while turning over with ignition on

Well I pulled of the coil to distributor wire measured 20 Kohms which should be within spec however I noticed an oily residue on the tip from my coil which is now pointing that way....I will post if I solve this very fustrating though since the first coil lasted about 30 years and the replacement is only 6 months old...argh.

Still no go and too cold outside to work on. I have a chilton manual and toyota manual would a Haynes manual help sort this out better?

You plugged the vacuum lines after removing them from the BVSV, right?

Is the choke working correctly? These things can appear dead in cold weather if not choked.

I hadn't plug the lines thanks for the tip. Choke was working just fine but I will double check that as well. Still too cold to work on until Saturday. minus 11 this morning.

Check your choke, mine was stuck open, once I got it working (yesterday) truck starts on the first turn.

Good news got her running yesterday. Bad ground wire connection was affecting the coil.

Thanks for all the help.
