A lot of different things can cause your Dodge 3.9L, 5.2L, or 5.9L pick up, van, SUV not to start. You might be wondering, “Is it the fuel pump?”, or “Is it the ignition coil?”... and the list goes on.
Well, in this article, I'll offer you my take on testing a cranks but does not start condition that has helped me nail them down with a lot of success and I think this diagnostic strategy will help you too.
Besides, knowing where to starting testing, before replacing parts, will save you time and money and in this economy, who needs the frustration of throwing money away.
Here are the contents of this article at a quick glance:
TIP 1: This may sound too obvious... but just in case it's not clear... a no crank and a no start condition are not the same thing. This article only concentrates on testing a no start condition.
The difference is that in a no start condition the starter motor in your vehicle does crank the engine but the engine does not start. In a no crank condition, the starter motor does not turn over the engine when you turn the key to start your vehicle.
If your Dodge pickup (SUV, van) is suffering a no crank condition and you suspect the starter motor, the following tutorial may be of help:
As you're already aware, your Dodge 3.9L, 5.2L, 5.9L pick up (van, SUV) needs three very important things to start: air, fuel and spark.
When your Dodge vehicle cranks but does not start...it's because one of these three components is missing from the mix. Knowing this is the key to successfully diagnosing the problem. Why?
Well, because now you can do some basic tests to isolate the problem in one of three main areas where the problem could reside in. Let's go into some detail about these three areas:
1.) Ignition System
2.) Fuel System
3.) Engine Mechanical System
OK, the list of possible things that can go wrong looks pretty long... but it is rare to see (or have) two different components go BAD from two separate systems at the same time.
The cool thing is, is that there is a diagnostic strategy that you can use to figure out exactly what's wrong with your particular no start problem. Let's find out more about it in the next subheading...
