Asked by Jan 29, 2015 at 12:51 PM about the 1998 Dodge Ram Van 3500 Maxi Extended Cargo RWD

Question type: Maintenance & Repair

When cold the engine turns over perfectly, but has no spark.  After a few attempts, or when the day warms up, it will eventually start and run perfectly.  When warm the engine starts perfectly every time. Changed the fuel pump, plugs, plug wires, distributor cap and rotor, engine shut-off relay, but no joy.

How do you know the engine has no spark when cold? Have you ever heard of Sea-Foam? Put two cans in your gas tank and a half a can in your engine and then run it for a while. It is amazing what that stuff does.

I know there was no spark when cold because I pulled a plug wire, put a spark plug on it, grounded the plug against the block, and turned the engine over. Also, I sprayed some engine starting fluid into the carburetor and turned the engine over. No joy. After the weather warmed up, around noon, I tried again, and the engine started after 2-3 tries.

Your fuel injectors are suspect here. Do what I told you to do first. It could be a fuel sensor though as well.

The problem is actually the computer. I had this problem with my 91. Through much pain I found blowing heat up the vent to the computer wot 45 seconds to a minute and the van starts perfect. Don't ask how I figured it out. Anyway I replaced the computer towards the end of the winter and no more issues
