Went to my local muffler shop to have the OBX Catback system installed on my 05 Convertible 6spd.

It started up like normal and drove it home about 15-20 minutes and parked it in the garage.

My wife came home about an hour later and wanted to hear it so I turned the car on but took an unusually long time to crank. I shut it off and started it a few more times back to back and cranked like normal.

Waited a few more hours and tested it again before bed and same results as earlier. Slow crank on first start but fine after that. Thoughts?

I mention that they also did my brakes and rotors. Don’t think it’s related but he did mention it being more involved than a normal brake job because of sensors?

thanks for your help

 

My first thought is to have the battery tested. They can cause many different issues. Long time to crank and slow crank need to be explained better. James

 

Thanks James, I think it was because the battery was disconnected for so long while they did the work. Driving it all day today started up like normal.

 

unrelated, sounds like a failing check valve in your fuel pump not holding pressure for startup
