SOURCE: car dies when driving,check engine light comes on.

There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

Recheck your timing marks. Sounds like valve timing is off. Check compression it needs a minimum 90 lbs to run. Bet you money the timing belt was put on out of phase.

Where is primary coil in 4 cyl. 04 optima


Well i dont really know Optima's but the most easy way to find it is to find the spark plugs that go into the block of the car and then follow the wires to the other end away from the block of the car to the other end of the wires and thats where your coil packs will be. Hope that is some help
