Ignition problems - slow crankin'?

my jeep has never liked the cold weather but now that it is warming up the ignition is acting like its still freezing outside. It starts like a weak old dog and takes longer than normal to crank.
i have just replaced the wires w/OE Autolite wires - no effect. Going to change sparkplugs soon.
Any suggestions would be great.

does your motor crank slow or does it just turn-over a bunch of times before it stats?

sounds like its turning over a bunch. but i'm not a pro mechanic either.

It will slowly crank and then get faster and sometimes i will have to hold the key down for almost 3-4 seconds before it starts. Which is always when its cold.
sometimes it doesn't do the slow (warm up type) crank but thats usually when its warmer.

also i am using 10-W40 oil is that too heavy? The previous owner used that.

O.K. sounds like one of 3 things. you could have a lose connection from your battery to your starter. i would check that first . (2) you could have a weak battery any service station can check it and see if it is weak. last and the most costly is your starter. if it is going bad it will keep getting slower and slower. check the others first and it might save you so dough.

10-40 should be fine. I use it year-round. Address the 3 items mentioned by OR Arkie. But do yourself a big favor and buy your Jeep a JuiceBox ignition system. Best $130 you'll ever invest in your Jeep. Better starting and idling are the two main improvements you'll see immediately.

i thought the juicebox was only for the 4.2 ( i would like to know if it can be used on the 4.0 so i can do it to mine ) i use 5W30 on my engine of corse it is new , i would onley go as thick as 10W40 if i was burning alot of oil and i dont think i would ever use it in the winter. next time you do an oil change try 5W30 and see how it goes. though it is probley a bad battery, an oil change is a good thing.

oops! I didn't notice that he had a 4.0. The JuiceBox is not available for the 4.0. The 4.0 doesn't need it. It is already a high energy ignition system.

Thanks guys for the help. I was thinking about the juicebox but thanks for the clarification on that too. Looks like I'll have to drag myself down to the 4X4 shop and get the Optima. Gosh hate it when i have to upgrade!

see ya on the trails
