2001 tiburon has no spark. replaced coil pack and check power in the wire harness to the coil pack all good.Also replaced spark plug wires to. What could it be?

a crank sensor will make you not get a signal to trigger the power for the coil so that may be the problem with it. If all else is ok, is the check engine light on to scan it for the crank sensor code.

3.7 V6, mileage?

most likely the HV wires bad.

then bad coil pack.

did you check spark directly at the coil pack?

i use 2 known good HV wires to do that and 2 good test spark plugs.

both plugs grounded to engine (shell)

that is how you test any wasted spark coil pack. 3 coil pack.

if that fails the FSM shows, unplugging it and check the coil resistances. if wrong the pack is bad,

keep in mind the res. can read ok and coil be bad ,due to internal insulation break down (internal shorts)

if thats ok. the resistance , make sure the wires are not (primary)

to the coil (the low voltage connnector)

if that is ok, its mostly likely a bad coil, (pray not bad PCM)

if tool-less? start with cheap parts , work to expensive. (guessing)





now wasted spark 101.

if one line opens , both spark plugs die. no spark

the wasted spark is wired in SERIES. ( like Christmas lights)

the magic cuts cost of 6 coil\'s.

so if the HV wires are say, cheap , carbon wire and open

you lose, both spark plugs. use MAG wire and end this issues.

get some nice NGK mag wire or Bosch Mag wires.

you can see i hate carbon wire. for good causes.

(carbon string wire)

mag wires is real wire that is coil spun and is inductive. it

has the correct impedance but is not a resistor its and inductor.

and lasts the longest , and worth every penny.

i had the same problem with my moms 90 sentra... it turned that it could of been either ignition coil or pickup coil.. if ignition coil is good then possiby it could be pickup

Normally we start with the basics, are the spark plugs firing and are the fuel injectors opening and providing fuel, and does the engine have compression.
Also, are there any stored trouble codes in the computer?
There is a relay that powers the injectors and fuel pump. You say you are getting fuel so we will assume that relay is ok.
The crank or cam sensor could have failed, or a list of other things.
You will need to figure out if you are lacking fuel or spark to the plugs to proceed.

There could be a few reasons it doesn't. It may be your spark plugs/coils, wires, distributor, coil pack, cam sensor, dist. cap, even the PCM. You need to test each part to make sure. That would be the only way to actually know. You would need to check the wires and pins. Anyone could cause it.

Check the right wiring diagram connections... 2002 Mercury Cougar 2.0 liter DOHC L4 VIN "3"



Also, I find few diagrams about Igniotn System...

Hope helps.

Check ignition coil pack for spark, at ignition coil with engine running disconnect one spark plug wire at a time, they should all spark, if no spark out of any of the coil pack, replace coil pack.

i had that happen plenty of times. be sure that the new plug isnt bad and ohm test or see if you haave spark on the new wire. good luck

Testing the coil packs.

1. Get an INSULATED wire and hook it to a ground on the car.
2. Get some one to help you
3. pull a spark plug wire off the coil
4. hold grounded wire close to, but not touching, the part where the spark plug wire connects
5. keep hands away from coil and have your helper turn the engine over ( start car and turn off)
6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced
7. replace the spark plug wire
8. test the rest

the spark of the comes from the battery . there for the problem is in the coil.
