95 Dakota No spark - Not splice
Hey everyone, I've been checking out this great forum for information since I have had my truck, and it has been a great resource.
A few weeks ago I noticed the problem whenever it had rained, no spark and no fuel pump. I got on here and found the issue of the notorious under fuse box splice corroding. I found the very red wire that goes from a 3:1 and corrodes. Mine was green with a single thread of wire connected. A bit of solder, heat shrink tubing, and some electrical tape and everything was great. Started her up and drove like a champ.
So, here I am about a week later and no spark. This time the fuel pump is kicking on and priming, so I am suspecting another problem. If you would recommend I check fuel pressure, I have a gauge but have never used it yet. I guess this could be a good first use for it.
1. I want to check my Crank sensor, so far I have only read to check resistance. It is a 3 wire plug as I understand it, so what pins do I test resistance through? Can someone give me a more detailed test pattern?
2. The other thing I would like to test is the Coil, I have only ever tested one other coil and it was a pack style that I could just test resistance between the different plugs. (Much like the 4cyl neons I believe) Is there some similar test for our Dakota coil?
Thanks in advance for your help, and please let me know if there are any other things you would recommend checking out. I will post a follow up as I make progress.
