2000 3.9L won't start
 

Hi, here's my story:

One day truck starts to run rough and engine light comes on. Codes were p0300, p0301, and p0305.

I went and got plugs, wires, cap, and rotor. Replaced the plugs and everything was great. 200km later I decide I'll replace the cap and rotor since I have them and return the cables since the old ones are probably fine.

After the new cap and rotor I ran it around the block, everything was great, and parked it for the night.

The next morning it started but ran really rough. I played with the cables, put the old cap and rotor back on but no different. I went and got new cables and still no different. Eventually, it got worse and now it won't start. It fires rarely but not enough to catch.

Help! and thanks in advance!

A few things you could check.

thanks for the links. I found the problem. someone poured bleach in my gas tank. :(

that sucks, i got my tank siphoned the other day :( hate idiots. maybe people are just jealous of the Dakota lol

are u kidding me?

i was checking the gas cap and it didn't smell like gas at all, just like bleach. I drained the fuel, the **** the came out was disgusting. It was yellow and quickly separated with lots of sediment. I had a quarter tank, drained it all plus splashed a few gallons of fresh stuff and drained that. However I think I played with it too much trying to figure out what it was. Now the plugs have oil all over them and the oil level is twice over full. so much for that truck!

Bummer man :( Some people are just idiots. Did you make someone angry? Or just idiot kids with nothing else to do? This is one reason why I never cared for the flip-open gas lids. I like the ones where you have to push a button or pull a lever from inside the vehicle.

Well, at least you found the problem. Now find who do it and solve that problem for good :icon_teeth:

I would be setting up a game cam, take the fool's picture and find out who it is! I have done this before, I took pictures with my infered game cam, no flash but still bright enough to see who was messing with things, they got a nice surprise when I showed up on there door step with there picture and the cops right behind me!! LOL
