Trouble shooting techniques.
1st we checked all the coil packs for volts, pulse(ecu signal), ground then took the coil pack with the plugs still attached and watched them fire.
Then he unplugged the 1st coil pack and the engine didn't try to sputter or anything. Then he went down the row untill he got to the 3rd coil pack unplugged it and it sputtered then he tried the 5 coil pack and it sputtered again. but when he did it to any of the other coil packs it didn't do anything. he looked at the plugs again and told me 4 of the 6 plugs weren't combusting in the block. They still looked brand new and smelled like oil with no fuel. except for 2. He then looked at the fuel into the rail and checked the psi and it was correct and then we checked the PULSE for the injectors and it was good soo we came to the conclusion that it had to be clogged fuel injectors. But i guess if you guys don't believe me i can shoot some video of the engine with 4 coil packs unplugged and start it up and run it. That should sway you guys to believe. Wierd huh!
