I have a 02 4.0 auto and when I try to start the truck when its cold it dosent want to crank over. I read some other post but couldnt find what I was looking for. I just changed the oil spark plugs and air filter less than 1k ago, changed the fule filter about 5k. Could it be the starter?? where is the starter at?

 

just to clarify, are you talking the engine is cold (as in hasn't been running today), or the outside temp is cold (as in don't stick you tongue to a metal pole)?

 

does the starter click or make any noise when you turn the key or do you get nothing?

 

check your battery.....they hate cold weather

 

battery was changed last month.

as is the truck hasent ran all day.

it just takes a little longer to start

 

Does it crank at all when cold or just nothing when you turn the key?

 

it will start but it cranks a cupple of time before it will start. like it take time for the fuel to get their

 

Sounds like maybe the fuel pump may be getting weak. How many miles on the truck?

 

itll have around 140,000 by the time i go to ohio and back. never thought of the fuel pump. I think its still the stock one

 

Turn the key to on and wait for a few seconds before trying to start it.

 

i had to replace my fuel pump when i bought my truck. forgot if it cost 200 or 300. could have even been 100. not much help... im sorry.

 

Well did you try cycleing the key a few times prior to starting?

 

Last time my truck was acting like that it was due to a poor battery.

At first I didn't think it was the battery because I bought a new one 3 months ago but I took it back to Batteries Plus and turns out I had a faulty battery.

Yay for free replacements.

 

yeah I have it still starts hard.

 

I know this could be stupid but have you checked your battery wires and starter wires?

 

I replaced the fuel pump at about 130K... and it was hard to start for a few months then it just wouldn't start anymore...

 

how about the battery contacts more than the battery what condition are they in ?

 

I cleand the battery conection when I put the new battery in.

where are the started wires at.

 

On the starter, might be loose...

 

get the starter tested at like nappa or autozone

 

It's not the starter if it cranks. Definently is a fuel issue. More than likely the fuel pump. I think mine just went out on me at 47K. (Waiting to hear from dealer)
