04 Heritage Edition no start
Bought an 04 Heritage. 4.2, auto, 97k miles. Been sitting for 7 years. Removed fuel tank, cleaned it out as best I could, new fuel pump and filter, new battery. Cranks over fine but does not start. I am getting good fuel pressure to the rail, getting spark to the plugs. I get 11.8 volts to the injectors when the key is on, 10.2 while cranking. I get about 12 ohms on the injectors themselves. I do not get any codes on my scan tool. When I hold the trip odometer button down while cranking to get to all of that, I only see one thing that might be the issue. dtc 9600 which I believe is a PATS transponder problem. I was under the impression that if PATS was the problem I would not be getting fuel to the rail. The fuel pump relay tests good as does the PCM relay. Theft light comes on for a second or two when you turn the key on then goes out. Blinks dimly when the key is out. I am using the original keys.
So if it is the transponder, can I just replace the key lock cylinder and reprogram the new keys? Or is there more that I will need to check and/or do?

No starting fluid, but if I splash some gas in the TB it tries to start and run for a second or two. Which makes me think it is the PATS causing the problem because I think PATS cuts off the fuel supply. The only other thing I can think of that it could be would be the cam sensor. The pump primes as it should. I don't have a gauge to check what happens after that. I removed the Schrader valve and turned the key on and gas shot out of there pretty strong.

I just put the leads into the injector plug, I did not test the sides individually. I don't have a noid light. I suppose I could just use a 12v light bulb and attach leads to it and connect one at a time the way you describe.

I fabricated a noid light. Ran one wire of a 12v bulb to each side of the connector individually with the other end on the neg side of the battery. One side I got nothing, one side had a solid light. Then I connected to the pos side of the battery and did the same thing. One side I got a solid light, the other side was a pulse. I did not try all of them, just a couple.
So now what? Is 2 gallons of gas not enough to provide proper fuel? Injectors gummed? PCM problem? Still no codes on my reader

PATS likely has injector pulsing inhibited.
A normal action from a PATS fault or any attempt to steal the vehicle that trips Pats.
Turn the ignition on and let it set about a minute and see if the PATS light flashes a code. Pats does a self test.
If yes what is the two digit code?

The theft light comes on for a second or so then goes off. No flash codes. I am starting to think the 7 year old gas has just completely mucked the injectors. I am gonna pull the upper plenum tomorrow night and try to get the injectors out. A buddy of mine said to leave them in the rail but pop them out and then crank it over. Put newspaper or something underneath to catch any fuel. Sounds like a fun time to me, but that will tell if they are firing. Hopefully I don't break the plenum. Gonna change the hoses while I'm at it. The PCV hose was broken anyway. I doubt that has anything to do with it not starting.

It's not a PATS problem since PATS proves out successfully Red herring.
Sounds normal.
I'd go with the high possibility of gummed injectors or gelatinized gasoline. Your buddy is dead on with his tips, just be careful. Make sure you have the phone number for 9-1-1 handy.

Yeah it sounds like a recipe for a burned garage for sure. Might be better off just spending the money on new ones and be done with it. The gas I drained from the tank looked like tea. Plus I scooped about 3 pounds of crud out of it. Needs a new tank for sure, but I want to make sure it is gonna be worth all that. I have about $950 in the thing so far and that includes the purchase price.
