- take one coilpack off, insert spare plug, ground it. Start, view for spark?
- Rotate crank sensor while ign on. Hear injectors click?

If both of those are good, fuel is still not reaching your injectors...

I checked it all, Fuel is at the Combustion Chamber, Spark is good (check with a Spark Plug tester) Crank signal is there (REF and POS) Cam Sensor is good,
After these long Tests I got Pissed and put averything back and Crank the crap out of it and the Engine started to run about 200rpm then 300rpm and after 3-5minutes or so it got up to 600-700rpm, it sound like 2 or cyl is running, runs smooth but weak,
Now I put the Scaner on and I've got a KNOCK SENSOR code, Knock Sensor ??????? does not make any sence,
I cleared the code, took it out for a ride, again runs smooth buy weak and when you rev and back off, rpm drop so low that you feel like it going to stall.
Came back, no CEL, ran the Scaner,still get Knock Sensor code.
This is all for today, I'll keep you all posted!!!!!!!!!

- Throttle Position Sensor works on cold engine. After warmup =5min, its no longer used, O2 will be used instead. ---> Clean or replace TPS

- Try knock sensor bypass:
