C4 Corvette Fuel Pump replacement

[@michaelruggiero6443]

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

[@RandomlnternetGuy]

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?

[@kaldarleifar]

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.

[@gregs_garage]

yeah I read that on the internet too.

[@danielskipper8844]

My 93’ does the same thing , am waiting for an answer also

[@gregs_garage]

Fuel pump

[@bradenwuesthoff5639]

Sounds like a fuel delivery issue based on the extended crank

[@tristandamosso8087]

This is happening to mine too I need to know what the follow up is

[@gregs_garage]

check out the other video. fuel pump is common.

[@MrJz97ss]

[@gregs_garage]

[@NathanielDowsey]

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

[@gregs_garage]

Swap an ignition module in. Very likely. Check fuel pressure if you can.

[@cksfixesmadesimple1036]

My C4 is doing that now

[@gregs_garage]

get your azz to harbor freight and check that fuel pressure. You know how we do it.

[@derrickadams3908]

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

[@gregs_garage]

Sounds like they are guessing.

[@derrickadams3908]

@gregs_garage Man I hope not. That's a grip to be paying

[@gregs_garage]

hope they checked fuel pressure first. Could be ignition related I guess.@@derrickadams3908

[@derrickadams3908]

@@gregs_garage They said it had plenty of pressure.

[@gregs_garage]

let us know what was wrong in the end...@@derrickadams3908

[@keithjett7819]

My 85 is doing that same thing

[@gregs_garage]

fuel pump. You only have 1 to replace on the L98

[@nathanieldowsey3268]

I have the same priblem

[@gregs_garage]

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.

[@kyariashay]

Sounds like fuel pressure regulator

[@bradenwuesthoff5639]

Hook up fuel pressure gauge

[@gregs_garage]

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.
