hi scotty I got a 2007 Camry v6 with more than 200k miles and it has a Long cranking start, I don't have check engine Light, recently replaced all spark plugs and coils, what can be wrong?
what can be wrong?
That thing is nearly 20 years old with high mileage, almost anything can be wrong. Did you install OEM plugs and coils purchased from a trusted source? You might want to check your fuel pressure and also perform a diagnostic scan for codes and live data. In particular if the long crank occurs primarily after the car has been sitting for a while you'll want to check for rest pressure in the fuel rail.
It's wrong to even replace parts through symptoms only.
Get the car scanned and tell what codes were retrieved
Thanks for your response, I replaced the spark plugs and coils due to engine code p0300 misfire, purchased from Toyota dealer, I got a blue driver scan and has no codes, its clean
