Hard Start Turned To Fuel Pump Diagnostics C4 Corvette

Had a hard start condition in this c4 Corvette with unexpected solution. turned out to have a unexpected fuel pressure or flow issue resulting in the extended crank.

Forgot to mention, when testing a pump in fuel I recommend using something less volatile and less vapors then gasoline. I like to use diesel fuel or make sure it's in a cool well vented area to reduce vapors.

That's why I tuned in, to see how to take it out. Nice video anyway.

Thank you for a great video and very informative 👍🏻 Amazing...! I have a 95 C4 with 95, 000 miles and the engine makes a popping sound when the motor is in full Throttle... like it's not getting enough fuel... so I changed the original Fuel Filter and the Electric Fuel Pump and it still does it... the new electric fuel pump is a (Percision Fuel Pump Kit)....Any ideas?

Please don't use alligator clips on the terminals inside the bucket of gasoline! If one came off and arced it would be bad news!

I have a 1988 C4, when I start mine up I hear this humming sound that sounds after the start. Almost sounds like a cat that's leveling. Then the sound goes away. I wonder if it's the fuel pump going out because after I start it it doesn't run strong. I've already changed the spark plugs, wires too.

I'm sorry but it seems to me that you should put in a high perf pump specific to the car and year, and not solder/modify another pump not made for that vehicle year and jury rig wiring, etc. just because you have the pump laying around...especially when it's a customer's car.

I think you dont know beans about a C4 Corvette & are trying to learn on the customers dime, ie switch out the fuel relay first or jump the wire.
