hard starting....
jonjon:
I don't believe it is related to the starter, as it cranks just as fast all the time.
I also have the factory starter heat shield still on it.
Vette Obsessed:
Guys, for what its worth 88 Corvettes have a gear reduction starter fitted as standard.
jonjon:
I read a tech bulliten (no-photos) explaining that it can be tested by disconecting the switch, and checking it with an ohm meter. Above 200 is no good, and 20-200 with temperature less than 95-degrees is also no good as well. I guess the switch should read 200 exact.
Can anyone with a service manual verify this for me...
Thanks.

.. you also should be aware of the COLD START SENSOR under the plenum... Its an easy check or fix or replace the thing..
The CSS, beside malfunctioning can also 'tar up" over time & then prohibits the quick reading of temperature etc interfacing the info indirectly back to the ecm incorrectly - hence the engine runs like a dog.. and chokes.. often carbons up.. out of the open road it chugs along fine.
If a new CSS is needed they are here in oz at a few place no doubt but straight away on the Corvette '84+ section of www.usgmsp.com & cost A$111 +gst.. here taxed delivered done etc (genuine GM not copy).. or are also available from GM in the U.S.A if thats closer for retail US$72+freight etc.
This is a common problem & sounds alot like the description your giving.
This is what it looks like.. note the small square twin pin head. Hope this simply helps you.

Thanks,
I just checked that switch with an ohm meter, and the reading was 37.5. My local chevy dealer said, anything under 20 on a ohm meter is no good. I just checked a brand new one out of the box, and it read 37.2. That seems close enough to be OK.
The chevy dealership thinks that i have leaking injectors.
