QuestionQUESTION: Hyundai 2001, replaced the following, computer,relay fuse,
coil packs, cam sensor, crank sensor, pressure to the fuel pump, and still no spark can anyone help. Thanks
ANSWER: I suppose I first need to ask how you determined there was no spark. You've already addressed the most common items that cause a lack of spark.
Remote possibilities would be that the wiring between the ECM and the crank sensor is damaged or shorted, or that the ECM itself is defective.
Does the check engine lamp come on when you turn the key to the on position?
Also, what model Hyundai do you have? Although I don't think so, I'm concerned that I may be overlooking something.

QUESTION: Hyundai is a accent and yes the check engine lamp comes on.
AnswerThe check engine lamp is a good sign that the computer is probably operating properly.
Your crankshaft sensor has an o-ring on it. Sometimes when replacing the sensor, the o-ring on the old sensor stays in the engine block and then the new sensor won't install properly. Check your old sensor to be sure the o-ring is on it. If not, you probably have two o-rings on the new sensor, preventing it from properly reading the wheel on the crankshaft.
I'd also like to know, if I could, how you determined you have no spark. Mostly, this will help me verify we're not headed down the wrong path with diagnosis and repair.
