Yeah Im getting verry good spark now. It still hasnt thrown the code 12. It threw that the one time cause I jumped the starter without the ignition wire hooked up. Got the injectors clean now so im going to install them and go form there. They were so clogged im about 99% sure that was the problem..

Well I put the injectors back in and still same old thing, BUT I took the gas line off the fuel rail, turned the fuel pump on and ran some gas out in a jar and for about every cup of gas that comes out 1/3 of it is water. So i'm going to take the tank off and clean it and the gas lines well.

Check the ground wire cluster located on the top passenger side of the valve cover area.....it's so easy to forget to bolt down those ground wires. They are hard to see unless you get right in there and eyeball them.

UPDATE!!! Problem fixed. I drained the gas out and there was about a gallon of water in the tank. So I dropped the tank, cleaned it out, flushed all the lines out, cleaned the filter, recleaned the injectors again and replaced the plugs again. Now she runs like a champ...

Yes and another fuel filter bites the dust....
Lol J/K. It's always something simple....
Glad your running again.
Now go raise some hell from the last place you got gas from because they have water in their tanks and they owe you.....
I think they should at least pay you for the parts and lost wages from their bad gas. I mean you pay enough for it right?

Sounds a bit extreme but what you don't know is some have leaky tanks or lines going to the tanks and it's expensive to fix for them.
So you got unlucky and got gas when their tanks were low and you picked up water and got charged for gas and water.
I used to work for a gas station/Service station and when it rained guess what had a lot of stalling vehicles.....
The owner wouldn't admit he knew the tanks were leaking the tank alarms were going off all the time.
The station was closed for several months they ended having to dig up their gas tanks and replace them because they were leaking.
