TSX has a very rough start. Once starts it runs fine.
My beloved TSX has developed a startup problem.
- It always starts but it takes 4-8 cranks and sneezes and misfires before it starts up.
- the starter sounds decent it cranks and cranks
- I replaced the fuel pump and the fuel pump relay and it didn't help
- once it starts it runs absolutely fine
- it has a rough start cold and hot. I can turn the car off and start it again and it will start very rough
- check engine light is off. I took it to Autozone and they said no codes
Any ideas? Any more diagnostics I can do?

could be dirty/clogged fuel injectors or spark plugs.. have you checked either of those?
#3
I haven't checked the injectors yet. Same question, do you know if injectors can cause issues only on startup?

Sounds a lot like a starter and or coil pack(s) issue. If it has the original starter, then definitely replace it. Just because something sounds "decent" doesn't mean that it's about to fail.

Thanks! I was leaning towards the starter too. The car is on its second starter but it has 240K miles and the second starter was a cheapo one from Autozone installed 90K miles ago. In theory it is time for it to go. I'll replace it this week and see.

Yeah those auto zone ones are crap. Get an oem, beck arnley or Bosch one. Definitely worth it to pay a bit extra for a quality part. Good luck!

Funny, I noticed that the older the car gets the more complicated every problem appears. If it had only 100K miles on it I would immediately have blamed the starter

You're welcome! Glad you were able to fix it. Hahah yeah it can be a bit tedious, especially when going off a sound or issue.
You can go crazy trying to search for a thread or video replicating that issue or sound- only to have 50 different opinions and hunches. The most annoying part is when there is no update as to whether or not it was actually repaired.

This time it worked every time but it took 3-4 more revolutions and misfires that's why I was in denial about the starter being the issue. It was totally different.
237K miles and my 1st Gen TSX still going, knock on wood.
