I had misfire codes, swapped the icms and it moved from cylinder 5 to 2, ordered a new one and put it in. car started good and codes were cleared. I turned off the car and put everything back together but 5 minutes later... now the car wont start. ive seen lots of stuff to check the temp sensors, fuel pump relay, etc but it just doesn't make sense that everything was fixed and now it just wont start. I got a new battery as mine was pretty old too but still nothing. any ideas? thanks.
