long cranking
Recently, after getting a code 34, I have been getting a long cranking condition. I usually have a little puff of smoke at start up (valve seals) but yesterday a slight puff of black. Seems to be a smell of fuel also. I cleaned the MAF and throttle body after the code 34. Could that have something to do with the black smoke? Code 34 hasn't returned and car idles and runs fine.
Any ideas?
Thanks

I have the same problem but only when it's cold. I have a procharger LT1
It just seems to be getting worse. I can hear the supplemental fuel pump kick on and off before I crank so I believe that's working. I'll have to put a fuel pressure gauge on it.
I didn't mean to jump in but I was hoping this was a cold start problem

Forgot one small detail. It did fire right up at first, and stalled Imediately. Then it wouldn't start. Could it have something to do with the code 34 I was getting previously?(MAF) Maybe relays? I am trying to look it up in my FSM, but any help is appreciated

If you turn the key from off to run and don't hear the fuel pump then it's the fuel pump relay causing your long cranking condition as the oil pressure sending switch will power the pump only after 5 PSI oil pressure is detected from the cranking.
