When there is moisture or it is cold out my dodge shadow has trouble starting and then once I get it running it cuts off while I am driving it.

windows fog up on the inside simply because of the hot breath of the occupants
this heat is cooled by the screen and condenses and so a fog is created
simple physics really - hot moisture + cold air =rain to over come this quickly run the air conditioner ( climate control) and that takes the moisture out of the air in the car and then the windscreen clears
you are going to say that it is too cold for the ac to run well at the same time run the heater until you have a pleasant temperature that is dry ( climate control--when it gets too hot the ac cuts in and when it gets to cold the ac switches off BUT the moisture that causes the fog on the windows is gone )

if it has a distributor cap it may have a hairline crack in it causing moisture to stop it from firing.Part outlets sell a plasticoat spray that you can spray on the distributor and seal it,causing the moisture to stay out/dry.You might want to try that,take a chance

Do you own a professional type scan tool that show's engine sensor data ?

I would replace the A S D relay. it's located in the fuse box under the hood. It's inexpensive at the dealer. My ASD relay was acting up, and it wanted to bog down while driving, and sputter pulling away from a red light. once it finally goes, the vehicle won't start at all.

I hope this helps

hi, if the truck starts and runs fine from cold but then starts playing up when it reaches normal running temp then has trouble starting untill it has cooled down if this is the case then i would say that your oxgen sensor(or lambda sensor for its proper name) needs replacing.
The reason it points towards this is that this sensor dont start working untill the engine is more or less up to temp so if this is when you start getting problems then this is what i would get changed first.

Let me know how you get on or if you need further assistance.

Save a lot of guessing and unnecessary expense & run into a PepBoys, or Autozone and have them scan for trouble codes (free) and go from there. If it's obvious from codes, what the problem is, buy the part while your there, but if not, get back to us with code(s) and we'll assist you further.

it does sound like a fuel pump problem and they are fairly easy. but make sure the ingtion system is good first. those cars are bad on distributor caps and rotor also the coils when the car is running good spray water with a spray bottle over the ignition system if the car dies you should start their. good luck

You should buy one of the manuals for this truck (their very cheap on ebay and they are very helpful on all kinds of little tricks, I think I got mine for like $1-2 or so

For my winter driving/summer driving I have completly different setups for my s.a.s. and fuel mixture (richness) screw and have very little troubles (live in MN)

clean out the carb and fit an inline fuel filter between the pump and the carb .

you have a sensor some were not likeing the heat. they can go this way sometimes. you need to run diagnostics as the engine is warming up and have it set to view the engine as it warms up to find the problem. it could be a cam sensor as they prone to do this when they are hot then work fine when they are cool.
