ls3 525 stalling
 

Hi,need help! 69 camaro crate ls3 525 driven 4k miles no problems then sudden shutdown with no codes,any ideas? thanks

That is a little light on details...

Did you verify good fuel pressure?

Don

yes,good fuel pressure,installed new aeromotive 340 pump

Any blown fuses?

Start with the basics, fuel and spark and take it from there.

A connector or wire may have worked it's way loose in the harness. What brand of harness are you using?

gm,all fuses ok

is it currently a no start condition or start and runs, but will stall right away, or eventually?

starts and runs perfectly for about 20 min then dies,sometimes starts after battery is disconnected then reconnected,but not always... is it possibly cpk sensor,but no codes

Uh, that would've been helpful up front. :lol:
