Hi, can anyone tell me if a faulty ambient temperature sensor would cause problems starting,, only in rainy weathe? 1998 1500

 

More likely to be bad cap/rotor, or plug wires.

 

Do you have a code for the temp sensor, or are you just guessing?
As HeyYou stated, most of the time a cracked cap can allow water/moisture to get inside and restrict your ignition spark... and check wires too.

 

Thanks, just guessing on sensor. Cap and wires are original, very possible thats the problem then?

 

Quite likely actually.

 

Thanks for the quick responses. It's rainy season here in Fla and nothing more frustrating than not being able to jump in and go. I'll follow up on your suggestions when weather clears

 

How long is that going to be though?

 

heh,heh...lol... belly laugh I take it you've seen the weather satellite pics? Anyways, once she started she runs fine all day. (is it appropriate to refer to your best friend/truck as she)

 

When the truck warms up, it effectively boils off any water.... or at least, makes it evaporate rather quickly. Let it sit, and cool again, and water condenses in places there shouldn't be any water.... giving you some odd performance problems.

The words "rainy season" clued me in.

 

OK, the neigbors are going to love me tonight when I keep the dry-out at 2 a.m. starting. That's when the next band of showers are coming through!
