Default My mechanic is confused.

My 1996 corvette died in traffic. My very good mechanic has replaced the fuel pump and distributor and has it running. But it takes a long time to get started. He needs to “grind it a long time to get it started”. A friend says maybe it is the ignition coil. Sorry I have no clue what is wrong with my corvette,

Throttle position sensor did that on my 95. One time I spent a half hour on the side of the road trying to start it. Finally called a tow truck and got it home. He rolled it off and the damn thing started right up.

I assume you replaced plugs and wires recently as well? It may be a failing TPS sensor also I would replace the ignition coil and Igbition Control Module and start from there it may also be a weak or bad injector...

Check fuel pressure bleed down rate.

Could still be a defective/bad OptiSpark, or plugs and wires

Sounds like you need a new mechanic instead of one shotgunning parts.
instead of throwing out random guesses you need someone to properly troubleshoot it.

Is he paying you the $100 an hour hes probably charging you to guess? I swear....
A simple fuel gauge and test light can solve this lil mystery. Keep us posted.

Yeah you need a new mechanic.

He's already sold you a new fuel pump and a new distributor? What's missing? It's really, really basic! Spark, fuel, compression, timing . . . and the engine will RUN!!!

I hope you saved your old (maybe good) parts!

Confused and mechanic in the same sentence is rarely a good thing.

^^^^^
This.

Your "very good mechanic" may be great at replacing parts, but he's a failure as a troubleshooter. Find somebody who knows how it's done. Preferably somebody who knows the peculiarities of the C4 LT1/LT4 Corvettes.

Live well,

Given the '96 has OBD II he should be able to track down the issue(s) with basic mechanic trouble shooting skills AND technology....
Time to find a real very good mechanic!
