Starting the ZO6

Do you guys have a rough start-up in the morning? whenever i turn the key, it takes a while for the engine to kick over. this isn't an issue on our '98 Pace Car, it starts right up. You think it's the camshaft(stock)? thanx

Z fires off as soon as the key and clutch saftey are in the upright and locked position. Very little cranking to fire off.

Mine started fine stock - still does heavily modified. I suggest a trip to the dealer if it is under warranty.

Something isn't right - have the dealer check it out. Mine always starts right up - like within a second or two of turning the key.

Re: Starting the ZO6 (jimmy2004)

I just recently noticed the exact same thing when I first start it for the day.

I also noticed at appoximately the same time the starting issue developed, my fuel pump became louder. I used to only faintly hear the fuel pump, but now it is clear as ever.

Hopefully, someone hear knows what's up.....

Re: Starting the ZO6 (jimmy2004)

I'd check to see if you have a DTC set (Diagnostic Trouble Code). The PCM uses the camshaft position sensor to determine when a cylinder is on its compression stroke for firing the spark plugs. If the camshaft position sensor has failed, the PCM then uses the crankshaft position sensor to determine (along with some other inputs) when a cylinder is in compression. This takes more engine revolutions, so starting may appear to take longer. The failure of the cam position sensor will set a DTC.
