It takes 10 plus seconds to engage and often will finally start after I have let go of the key. Occassionally is does not start until the 3 or 4th try. The problem does not happen when the car is cold (first thing in the morning) or after the car is warm. It only happens when the car is somewhere between warm and cold-usually when running errands. It has been in and out of the shop and the following things have been repaire: fuel pump, spark plugs and wires and some minor electrical connections have been fixed. I am all out of ideas and running out of patience. Please Help!

Here is a start. Have the pcm checked to seeif it's sending a signal to start the car if not then see if bcm is doing same as i'm sending diagrams for it. Here is also a tsb from gm that covers hard starting.

NOTE: GM¬ UPPER¬ ENGINE¬ AND¬ FUEL¬ INJECTOR¬ CLEANER¬ is¬ the¬ only¬ injector¬ cleaning¬ agent¬ approved¬ for¬ use¬ with¬ General¬ Motors¬ fuel¬ system¬ components.¬ Other
injector¬ cleaners¬ may¬ cause¬ damage¬ to¬ plastics, ¬ plated¬ metals¬ or¬ bearings.¬ General¬ Motors¬ has¬ completed¬ extensive¬ laboratory¬ testing¬ of¬ GM¬ Upper¬ Engine¬ and
Fuel¬ Injector¬ Cleaner, ¬ and¬ can¬ assure¬ its¬ compatibility¬ with¬ General¬ Motors¬ fuel¬ system¬ components, ¬ as¬ long¬ as¬ the¬ cleaning¬ procedure¬ is¬ followed¬ correctly.
There is also a thing called top tier gas that is not available at all gas companies that have to do with clean injectors. If you do short hops like less than 10 miles driven each way this can effect your car. Check with a dealer for specific tsb for this. It gives the stations where you are in U.S. And CAnada

May be a bad or dirty idle air control valve.
Let us know if this solves it.
Good luck !
