I use quarters LOTS.....carwash and Cappuccino at local Shell Station takes 8 quarters....exactly What I over pay in gas I spend on Cappuccino.....did I just say that nonsense On the start issue of 3 seconds......I prefer a little lag in starting to get some oil pumping at starter rpm before it reves up after started if I have a foot on it.....a better chance to pump up them Chain Tensioners and Lifters that have leaked down |

Re: Long cranking
Up to 3 seconds on my 90 as well, but tends to be shorter on a hot start. However, I'm in the habit of turning the key ON and listing to the fuel pumps settle before rolling the starter. It, seems to make a difference by maybe a second or so after sitting for a few days.
I read in one of my tech reference manuals that quick starts was one of the goals engineered into the Opti-Spark distributor on the LT1/4 motors. Anywayz, I mention that because that was one of the first things I noticed about my Z was the longer cranking time than my 95 LT1 Vette had. The 95 LT1 with its Opti would reliably fire practically instantly: hot or cold-COLD - it didn't usually matter!

Re: Long cranking
Where's Steve here - is this something that's coded into the ECM? Can you explain this a little more in depth?
This is pretty interesting here... Does Marc's code over-write for hard hot re-starts have anything to do with the 'find #1 before starting' code? Mine is the first fuel injected car I've ever owned, that didn't start immediately. I usually keep them tuned well, and mine is pretty cleaned up now (32k), and does start marginally faster with Marc's Memory / Calibration Module here...

Re: Long cranking
That "rubber liner thingy"? I've had 3 C4s 2
from new and didn't have one? Do the later cars, 91 on, have them? Often wondered what to do with my quarters... |

Re: Long cranking
My statement is a very abbreviated, It refuses section in the FSM 6E3-A-22 thru 29 and 6E3-A-52 & 53 basically when cranking the ECM must see the Camshaft sensor at #1 before it starts. I could be wrong but that's how I read it.

Rubber Liner Thingy on Ebay I kind of like to spin the crankshaft with the starter a bit as the oil circulates just a tad before it revs up.....I forget exactly when the oil pressure starts showing on the gage but I think I recall oil pressure showing a tad when doing a compression test after a few crankshaft revolutions.....
