My 1998 Dodge Ram 1500 with 5.2 just took a crap on me. I drove my truck to the shop I junk cars out of. When I went to start truck to hook to trailer it fired and ran for a second or two then died. Then after that I got nothing. Poured a little fuel in intake and nothing. Did some googling and suggested to check spark. I checked wire from distributor to cap and no spark. Then went back and checked coil no spark. Power wire on coil is hot. When checking the wire to tell it to fire I found it was not getting it's connection. So reading up says possibly crank sensor. Was gonna look at it more the next day. Did some more searching online and when I went to shop next day I messed with the crack sensor wire connector and it started right way. Moved truck around a few times that day with no problem on start. I went to Kroger on my way home that night. When I came out I got no spark. Went and got crank sensor and changed it. Still no spark. Still not getting signal at coil to spark. Went back next morning to see if it starts like it did before but still no fire. Friend is saying computer probably.
I would think a computer going out would have signs. Truck ran fine when it was running. But would not fire after warm and turned off. I did have a misfire on cylinder 8 a while back and changed plugs and cel went off but came back on a few months ago. Never got to see if it was misfire or what cause I lost my elm 327 device. Reset computer last night so now the light is off.
I'm hoping someone has an ideal of what to look at. I'm hoping not cam sensor. That's under the cap and it's hard to reach the back of the motor on this model. Hoping to find the problem without spending a lot of money to find it.
Edit,
I found how to test Cam sensor (pickup coil). Information says the signal wire should be putting out 5 volts to 0 Volts while cranking. While my dad cranked I seen 5 volts here and there but usually 0 to 3.5 to 0 to 2.5 to 0 to 4 to 0 to 5.3. So I do see 5 volts popping, Can't seem to find out if it should actually be 0 to 5 to 0 to 5 or if it will actually bounce around. The Pickup coil is 50 to 80 dollars. I don't want to pay that much for it and find out that isn't the problem. Already dished out 68 dollars for the crank sensor.
Would like to get my only vehicle back to running. I've only been without a vehicle for a few weeks in my life since I started driving. Sucks asking for rides every time you have to go somewhere.
