Also if you need wiring diagrams, we do have access to a free Chilton’s online. The link is in the “How To” forum. Chilton’s is still very basic but might give you a starting point.
Alldatadiy.com has decent prices for a subscription that gives you access to factory information. Chilton and haynes seem to be too general IMO. Buying a paper factory manual on eBay is a good option for a DIYer as well. Doesn’t make much sense for a pro, but you’re only working on one or two vehicles. Look for the “Service Manual” as opposed to the “Powertrain Diagnostic Manual” or the like, though it wouldn’t hurt to have the full set if you find a good deal. The factory
service manual has lots of great info from truly complete wire diagrams to detailed explanations of powertrain management and other systems.

Socal, my reference for the rpm is about, if crank shaft sensor is not giving a feed to computer, asd relay will not be fired to give you ignition or fuel.
That is a first to look at when no rpm’s are registering if you have a tach.Now that I said that, you turn key on and you heard fuel pump run a couple seconds, Right? That is normal when you first turn on the key, call it a prime. Chrysler with the asd relay will not give battery voltage to them components until things like a signal from ckp sensor.
If battery is low power as others mentioned before, may not have enough power to supply anything while cranking engine. Charge battery and then start looking at what ways to check and verify crank shaft sensor to see if that is problem. Did you do work just recently where some thing could have got tugged on, yanked loose?1) What engine does your dakota have – 3.9/4.7/5.2/5.9?
2) Is it an automatic or manual transmission?
When I bought my dakota (about a year ago), I experienced the same thing. It turned out to be a loose connection on my negative battery terminal. Take your terminals off, clean them (both battery post and terminal connectors), reconnect them, and ensure they are tight, and try again.
Keep us updated, I have the factory service manual, so if you cannot find anything with our chilton’s account, I can help locate some info for you.
i had the same probelm with mine when i let the battery die. I just had to hold the gas down alittle and it started right up and then had to let it run for about 30 mins.
