Lets have a look at this old 1989 Chevrolet C4 Corvette that was towed in for a no start diagnosis. When the customer explained the symptoms it sounded all to familiar to another video we did on the same engine, make and model. Be sure to check out the links below.

How do six injectors go bad at the same time? Seems strange to me.
Very bad Injector Waveform for sure flat-lining right out super easy Diag On this One Eric O good Video @SouthMainAutoRepairLLC
Excellent video! Thanks for the diagnostic explanation and demonstration.
I have the same car and it starts cold just fine but go on a drive , park for 30 mins and then no start with no solenoid noise and no cranking. You can push start it though.
Just watched the first two corvette videos . Yeah on the new injectors you could see the slit dip on the ramp side where the injector opened. Your a very talented mechanic! Explain things very well and solve the problems before throwing parts at it! Good job!
I disconnected one WIRE on the cooling fan and wired it back now the car will not start WHY????
Hi Eric! We have a 99 C5 Corvette in our shop that belongs to my sister. While replacing the starter, one of the guys hooked up a gray/black wire to the positive on the starter that didn't belong and ever since that happened it won't start.
They put a new PCM behind the right front wheel which solved nothing as well as a new key ignition. That's where they have gotten with it then asked for my help
Its cranks but won't start, has no comm, lost fuel gauge it stays on Empty, engine temp gauge reads 270 all of the time when they were working fine.
no spark, no power to the fuel relay during cranking probably no injector pulse either during cranking didn't check because fuel pump not running.
With the key switched on this thing is sparking on #1 and #3 coils continuously using the alligator clip on coil and other end held close to ground.
This is like a high RPM spark not just a tap tap tap, its like a blur spark. I assume it sparks on all 8 like this
Relay # 52 under the hood is the ign relay and with the key on it non stop buzzes no doubt because the coils are firing non stop.
If I power that relay it up it runs the engine fan wide open.
I don't know to me it soulds like some grounds may be burned out and some wires fused together somewhere.
Where would you start on this?
I got same problem…ran fine on sunday no start on monday
Thanks for the the vid, when you work on those c4’s buy the original gm electronics . Had a mas air flow cleaner code I couldn’t get rid of. Replaced the new after market tps from a previous code with a gm one from eBay. Code gone runs like a old Chevy truck again! This vid got me thinking about my tj Wrangler, on a warm day on a long pull ,I shut it down come back to it & it goes blub, blub,blub, then clears out & runs fine. The injections vapor lock from the heat of the cats below the manifolds. Just like the carbs of old.
Do you do any over the phone diagnosing?? Think I need some good advise
Let Hannah do the presentation while you record. Just a suggestion.
hi i have a 90 c4 here in the uk and am looking to find out what cartridge i would need to fit into my snap on MT 2500 scanner
Happened to my 92 crank no start it was the knock sensor had two replaced them both .
I luv Corvettes 😳
Were the on1 port location eny one no
this is A Kool Cat!! enjoy videos and his easy flow on explanations and approach.. keep on truckin partnr!!!
Hi, I have a problem, I have 1992 Corvette, and change the distributor, I buy in Autozone for 1992 Corvette, Camaro, firebird applications, the car start normally, after 3 minutes the security light flashes and wehen I turn it off and try to start the security light stays on, after 3 minutes the car start again, as you did in video and remained the same, I put a bipass on the key resistence and nothing, can help me please?, thak you, greetings.
The scope doesn't lie! Great Video!
I have a 84 Corvette and it will start up then stalls out right away unless I apply the gas pedal until the check engine light comes on
Thanks for the video.
Good find
But you do it better.
You are really a genius. Thank you.
if you think its the fuel pump then stop wasting your time with your snap on junk, I watched you fiddle with that and jump wires and just laughed, dude just put a pressure gauge on the fuel rail connecter , that's what its for , takes about 60 sec to figure it out .
got a 88 Corvette it was my dad's till he passed won't start but for two seconds keep watching videos on how to bypass the vats and use resistors and nothing it's stubborn as hell. no idea if it's the fuel pump relay, security, injectors. could use some good advice. btw mine is a wimpy white automatic 88 lol
So I have a 93 40th edt* when I'm driving the dash lights will turn off and if I turn the car off while the dash lights are out it won't start? if lights are on and I kill it no problem firing back up???
Super videa, jen tak dál… Made in czech republik
good check out
Wow these Chevys… Btw I like your ending motto.
Man that's a good lookin car. Really wish I had bought a C4 instead of a C3, but when I was ready to buy I couldn't find a SINGLE one that I liked. So I ended up with an 81 4-spd t-tops.
did the customer have it fixed? if he did is there a follow up video??
8 Bosch II's at 24 lb rating. You're golden. Call FIC, (Fuel injection connection). Great product, service, prices, warranty.

Is there anywhere i can get a South Main Auto sweatshirt like yours???

Hannah strikes me as having no time for all your nonsense, Eric. :p J/k, she's a great helper and seems confident when she's at the shop!
What is he asking ?
