Re: 9 deg outside wj hard start

Dude...it's 9 degrees...it took my body a few minutes to get started after going outside.

Mine started a little sluggishly too, but I was expecting it too. It's friggin brutally cold out there.

In my area Northern Virginia it was about 20*F. The Revved up to 1k RPM and stayed there for about a minute.

Re: 9 deg outside wj hard start

That's pretty normal that your 4.0L would have a hard start. That's how mine was.

Re: 9 deg outside wj hard start

It was -2* F here when I went to work on Friday (I have pictures of the temp). Once it reaches negatives, I declare it cold. Jeep started up just like normal.

Re: 9 deg outside wj hard start

Never had a cold start problem with my jeeps, the 93 ZJ 4.0L or the 01 WJ 4.7L. They may turn over an extra time or two before catching at -10, but they have always fired quickly!

Re: 9 deg outside wj hard start

Mine hard starts all the time after sitting a while lol, but with the cold this morning it was no different. How old are your plugs, coil and fuel regulator?

Re: 9 deg outside wj hard start

Maybe when it warms up a bit you should change the regulator. I dunno if you know, but its a filter/regulator unit. I suspect thats whats causing my hard start, but for you, i'd just chalk it up to that deathly cold we got.

Now lets hope for a blizzard this week!

Re: 9 deg outside wj hard start

Try adjusting the bands??? Its part of the regular maintenance schedule for the 42RE, they suggest every 2 years or 24k. My tranny is gahbage if its too cold, holds 1st way too long. I plan on adjusting the bands as soon as it warms up some.
