seems to be the primary fuel pump, it uses both fuel pumps when it´s starting and then switches to using just the primary, and if the primary is broken it will shut down.
Sounds like lack of fuel. Listen for the fuel pump to prime when you turn the key? Just went on some 2001 forums and apparently a bad primary fuel pump and/or clogged fuel filter is a common problem with LT5s. Spark is ok? Fuel pressure specs should be between 40-47 when running. Old gas in there?
My 93 is in the shop now. It starts and then stops. They called me today and said it's the distributor/ throttle body needs to be replace. Cost is over $1100.00
I got the same thing with mine and my fuel pump is not that old!!!!. Driving down the road and boom!! She dieszz on me but a few minutes of sitting. She starts rite back up and im off againnnn 😮😮😮😮😮😮 then im thinking the module maybe going out... Help 1991 c4 Corvette
Went to good ole harbor freight. Fuel pressure tester shows 5 psi! Jumped fuel pumps and still 5 psi. Fuel filter next then I’ll do the pump. Kinda doubt it’s the filter.
Is sounds like idle air control valve or have you changed the plugs in it Sounds like a bad feel pump or bad feel injectors Or a dirty throttle body

yeah I read that on the internet too.

Sounds like a fuel delivery issue based on the extended crank
My 93’ does the same thing , am waiting for an answer also
Fuel pump
You get this figured out ?
Yes check out the other video
This is happening to mine too I need to know what the follow up is
check out the other video. fuel pump is common.

Sounds like they are guessing.
@gregs_garage Man I hope not. That's a grip to be paying
hope they checked fuel pressure first. Could be ignition related I guess.@@derrickadams3908
@@gregs_garage They said it had plenty of pressure.
let us know what was wrong in the end...@@derrickadams3908

Swap an ignition module in. Very likely. Check fuel pressure if you can.
Throttle positioning sensor
Was fuel pumps
Hook up fuel pressure gauge

My C4 is doing that now
get your azz to harbor freight and check that fuel pressure. You know how we do it.
My 85 is doing that same thing
fuel pump. You only have 1 to replace on the L98
I have the same priblem
get a fuel pressure kit at harbor freight. If it doesn't show 35-40 PSI with the key on you likely have dead pumps.
See my other videos about the FIX.
Sounds like fuel pressure regulator
