I was working on my friends car when i pulled his Spark Wire to see if one of his cylinders was dead. I went down the line of pulling and placing the wire back.. all of a sudden it died after i got to the last cylinder (#4). Then his car wouldn't start back up! What should I do? Its getting fuel, air, compression, just no spark(i checked doing the spark plug 2 a ground test..no arc)!!! Has Anyone ever had this problem? What should I check? Thanks!

 

spark plug wire?

 

check the coil

 

I Put My Newish NGK Blues on his engine and they still didnt work!

 

How Do I check the coil?

 

these are easy to take out doing just what you did.

normally you just swap the dizzy for a known good one. i've seen coils test close spec that would not fire a car after that spark plug pulling. changing the dizzy has always been the cure around here.
