Isuzu Ascender: how difficult is it to replace ignition coils

This answer was rated:

how difficult is it to replace ignition coils on a 2003 isuzu ascender. Also, if I had 2 recently replaced will I be able to discern the old ones from the new, or is there an easy way to test them to see which ones are bad?
Hello! Welcome to the site! Thanks for coming! I'm Ron Z. I'm here to provide as much info and insight as I can, to best answer your question.

Is this the 6-cylinder or the 8-cylinder engine?

Customer: replied 3 years ago.

6 cylinder


Great! Thanks!

Ok- replcing the ignition coils isn't that bad of a job at all. I've wrapped up the procedure to replace the coils into a PDF File for easier viewing/printing. Download the procedure HERE

As for the coil difference- you should be able to spot the ones that were recently replaced. They're usually a different color or will have a different brand name on them that should stand out against the originals. Once you get in there, it should be noticable.

As for the test- Isuzu does not supply any electrical info on the coils such as Ohms, so there is no "official" test procedure. However, using an In-Line Spark Tester you can test the coils to make sure they are firing. You can usually pick up a spark tester fairly cheap at any local parts store.
