Well this is my first post in the LS section. Ok, here is the story: Picked up a 2000 Lincoln LS v8 with a bad engine and no keys. Got a known good engine for it (and installed it) and had a locksmith come out and program 2 new keys for it. After I finished installing the engine and hooking everything back up, fired it up to check everything. It ran well for a few min then suddenly shut off? Check fuel pressure- good. Now it just cranks and cranks, but never starts! I also have acess to the SCT software, so I tried disabling the PATS in the tune- still no luck. I have "noid lights" that plug into the injector harness to see if they are "pulsing"- they are NOT. So I tried replacing the crank position sensor- no change. So before you ask: Fuel pressure- good Crank Position sensor- changed PATS light flashing- No Injectors getting a signal/"pulsing"- No Cranking over- yes Does it even try to "fire"- No Any ideas???
