My 1993 Dodge Dakota Sport with a 3.9 liter Magnum will not start in the morning. I think it has something to do with the fuel system plus perhaps some electrical. I have a brand new fuel pump, second pump since march. I traded the one out I bought in March because I thought the issue was solely the fuel pump. Here is what happens when I try to start it first thing in the morning. Nothing but crank, crank, crank. If I wait until noon when the sun has warmed up, I turn on the key and I can hear the fuel pump run. It runs for about 30-40 seconds and then stops. Then the truck will start, but not until the fuel pump has stopped running. When I try this in the morning I do not hear the fuel pump take off like this, only after it has warmed up outdoors. I am truly perplexed.

 

Rapid Roy, Your problem sounds similar to a problem we have been battling with on our 92 5.2 Dak for a long time now. There is a post from cdpalmerjr which started on Sept. 22nd, you might find helpful, he did a lot of troubleshooting. As a matter of fact we tried using a hair dryer this morning (its just above freezing) and the Dak started up in about 5 minutes. Good Luck

 

Thanks, I'll look into it.

 

Hey just tried the hairdryer trick on the ECM and it was about 2 minutes and I could hear the fuel pump kick in and the truck started right up. Thanks for the tip dobaroy. Now to get a new ECM.

 

Cool trick and one to remember

 

Cool trick for a hot fix...LOL
