Yah. I have a 2003 dodge dakota v6 3.9 standard transmission. She won't start.... It was driving fine came home went to bed woke up she wit start. Originally I thought my battery had gone. I juiced it up and still can't get it to fire. My fuel pump is turning on she's cranking fine. I have spark at my plugs. My fuel tank is basically full. I tried spraying a quick start into mix with the air to see if it would at least start that way and still nothing.

When you sprayed starting fluid in, did it fire then stall or not fire at all? Fuel pump turning on doesnt mean its working correctly. Will need fuel pressure gauge to verify that pressure is in spec. Do you have access to a code reader? If not, possibly borrow one from local parts store and post any #s here. How did you test for spark?

Spraying the starting fluid in didn't seem to make any difference which is odd. I checked for spark using the driver touching metal method. The fuel pump is less then a year old as well. My engine light is coming on but it's not giving me any codes.

How many plugs did you check for spark? Prob gonna need a better scan tool. Got noid lights? If so, check for injector pulse. Still need to take a look at that fuel pressure with a gauge to be sure. Maybe one of the veterans here will have some input.

 All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
