Hello All,
I'm new to the forum and looking for some help. I've got a 93 Dakota V8 2-wheel drive. The truck starts and runs fine except when the weather is damp. Yesterday in Michigan it was rainy over night and in the morning, went to start the truck, it would crank and crank but no start? Pulled a plug and grounded to the exhaust manifold and had spark? Put the plug back in and still no start. Also sprayed starting fluid just in case of no fuel.

This morning it has cooled off ( 30 degrees) and dry, went to start the truck and it fired right away. This also has happened over the course of the summer, it would crank and eventually fire, yesterday nothing?

Does anybody have any ideas what to check first? Thanks in advance!!!

 

Welcome to DF!

Lots of possibilities from a bad fuel pump to a bad coil to the notorious power splices. Check the FAQ in this section for a good write up on it.

 

Thanks for the suggestions,

I'll check the notorious splice this weekend, maybe the dampness in the engine compartment causes an intermittent condition. Funny thing though, when I pulled the plug it had spark?
I'm thinking I may be able to rule out the fuel pump, I replaced it last summer. Just in case though, if it was the pump or wiring wouldn't the motor have at least attempted to fire when I sprayed the starting fluid in it, that's how I discovered the bad pump?

The truck has 140,XXX miles on it, would it be time to replace the coil? The cap and rotor look original so I think I'll change them when checking the splice.

Thanks again!!!

 

Maybe it is time for cap, rotor and wires. Good luck with it.
