step #1 would be get the code..
You are checking at plug or coil?

spark at #4 plug? shared cylinder..if yes #4... swap wire with #1 cheeck see if failure followed swap. that would indicate wire issue

im checking the coil,the wire i just replace them recently and try different wire but still no spark coming out from the coil #1,and i check the secondary resistance on the coil 3-6 1-4 5-2 no reading on 1-4 but the rest are okey .

if you ohm'ed th coil and 1-4 is open the coil is bad.

Now why did you change coil?
if for routine maintance return and get a OEM product using the old one meantime...

If you changed for a failure of 1-4 coil...
post all codes you have.
vehicle is STOCK no modifications...
secondary ign is QUALITY - no "gimicks" first suspect in coil failure secondary "load"

replace the coil and solve the problem thanks Kev2 for the help
