98 voyager won't start when cold.

I have an intermittent problem with my 98 voyager not wanting to start when it is cold. I bring it inside and warm it up, it starts fine. I have added dry gas and filled the tank with premium gas and it started fine for 2 days. This morning, it won't start. I am going to lose my job if I don't get this fixed. Had it in the shop, shop owner says nothing is wrong. No check engine lights, have flashing lights on dash but have had them since I bought the car 2 years ago. When I get the car running, it runs great. no miss or anything. Any help is welcome.

Check your instrument cluster for bad solder joints. Next time it happens try hiiting the top of your dash to see it that helps,

When it doesn't want to start does the engine turn over when you turn the key to start or do you just hear a click or nothing at all? Are the battery connections clean and tight? How old is the battery. The solder joints are a possibility but there's simple things to check first.

Battery is fully charged and car turns over but just doesn't start. My dad checked the spark plugs and distributor and there is a spark. We are working on the fuel filter and while doing that, the nipple to the pump was broken so we are replacing the pump as well. Hopefully that fixes the problem. If not, I am sure a couple gallons of gas and a lighter will do the trick HaHa.
