Chevy Corvette - No Start When Hot (The Diagnosis)
Автокөліктер мен көлік құралдары
Let's have a look at this old 1989 Chevrolet C-4 Corvette with the 5.7 Port F.I. engine and see why the heck this thing will not start when the engine gets up to temperature. It starts out running OK but then takes a turn for the worse.

It also reminds me of how many tools I don't need because my cars are older than that and have carburetors instead of fuel injection. I do have a timing light, vacuum gauge and a CO meter though.
Second video I watched of this guy .... damn, he knows what he is doing and knows how to use his diagnostic equipment....he had my attention every moment - nothing boring here !!!! I would change all the injectors to be 100% I cured the problem. Very well done - didn't change a dozen parts to eventually solve the problem !!!! Great narrating too !!!!

To me, OBD1 is sitting in a broken car in the garage with my dad as he clicked the key on and off for the secret handshake, then counting the lights flashing to get the code.

I have an '89 Iroc-Z with the L98 engine. I had the same problem and it turned out to be faulty injectors. There was way too much resistance for these things to fire. I got a fresh batch from injector connection and never had start issues since. Great video on how to diagnose a no start condition on an L98!
From my experience, a single shorted injector on a bank-fired PFI system will pull the entire bank down and prevent it from firing. Quite common on OBD I GMs. Interestingly, those Multec I fuel injectors that GM used, the coil is actually exposed to fuel ; they use the fuel to cool the coils. Allowing fuel to sit for a long time, or even using harsh injector cleaners, can eat through the insulating varnish on the coil wires and short the injector. Luckily, whether by design or the limitations of the technology of the day, the injector drivers on these GM PFI systems are built like brick shithouses, and usually survive a shorted injector or two. Certainly can't say the same for these new SFI systems! Awesome video, Eric! Great diagnostics and good process!

I also love how even your videos from 7 years ago are still just as valuable and fun to watch as your currents ones!
I worked in a GMC dealership in the early nineties, worked on a ton of these tpi injection systems. Replaced a lot of injectors. One big issue these had was when ethanol fuel came out. Fue would flow over the windings to keep the injectors cool. High concentration of ethanol would strip the insulation from the copper windings shorting the injectors. Gm even had a technical service bulletin on the problem
LOVE the scenery of you town. Reminds of Mayberry, Andy, Opie, and Barney when I was a kid.

Howdy Erick, I recently had same problem with my 94 Vette. I watched your video and I thought my prob might be same as yours ended to be. I purchased new injectors from corvette mods, rep,aced and didn’t fix my problem. So, I ordered new optispark and water pump , I took old parts off with no problems. My 94 is very clean .did not show signs of oil and or water on optispark, I replaced both seals as well on timing cover, installed new distributor abs water pump, I also went through harness checking possible brittle wires and connectors. Ended up running new grounds from battery to injector rail ground point and body to block. Cleaned throttle body, already replaced icm, solenoid and the easy stuff a few months ago. I’m pleased to say your video helped me learn my C4 in more ways than most. After I put er all back together with new optispark, she purrs and runs great now. I’ve had her about 14 mos. hadn’t put 100 miles on her before she started the engine stall stuff. I believe my problem may have been related to insufficient grounding and or the Optispark replacement . Havnt found a for sure fix for similar problem. Thought I would share my results. Thanks for tutorials. HaulinAss Transport 1.
Nice! I have been chasing what I thought was a heat soak issue on my Malibu ski boat which has port FI for about 3 years now. All the basics have always checked good such as fuel pressure, spark, and power to the injectors. I have never thought to check resistance on the injectors when it is acting up. Love the videos!

Appreciate the way you run through your diagnostic tool and how you explain what you're doing. Broke my next seven years ago so I've been out of the loop for a long time.

Anyway buddy of mine in Manassas has a collection of Corvettes so I try and pick up on all the Corvette videos I come across. Coming across your page and the way you explain not just this car but all your other cars is very helpful and educational. If you've got some mechanic who's on the border of being a competent mechanic and a master or really good mechanic your page and the way you go about Diagnostics and explaining what you're doing could really help some younger guy who's on his way up on the talent ladder. Anyways, keep up the good work brother, please don't take it as an insult when I say it's very entertaining to watch how you go about doing things. I mean that in only the most positive way.

Great show. I did an '88 Vette injector rebuild (you have to remove the w/s wiper motor) and I found all the screens slightly clogged (30 years). New screens & cleaning did the job. But for a professional mechanic like you- replacement is the way to go.
Those older-style injectors were never meant to have 10% ethanol-laden gasoline sit inside them and heat soak for prolonged periods. If you think about it- an injector is a type of electric (stepper) motor. If any (even low a voltage) electric motor is kept from moving, or a "drag" or "load" on it's rotor- it will build up heat, and (especially in the small windings of these) become weak, and eventually burn out. The gumming properties of the ethanol build up, shorten the throw of the pintle, then this weakens and burns out the coils. Also- given the hygroscopic nature of ethanol (why it's not used in aircraft) I'll bet the insides are also rusty. Eric- after replacement of these- could you please autopsy the weak units and show us- to confirm or dispel these ideas? Thank you so much!

That was a nice blast from the past. I remember when that system was a regular at our shop. We never had that nifty injector tester, but would use an old bit of harness and manually pulse the same way via the ground side, then check them with the 'ol multimeter. Old fuel plus fuel system additives is never a good combination, and those old solenoids never love the heat soak.
You are a great diagnostician. The number of times you rechecked to confirm the car is not starting was remarkable. And yet, that's just what diagnosis of complex systems needs.

+anti0918 Not to mention the generic '80s casio keyboard music during the GM PFI description and operation segment. I almost lost it! Hahaha!

Zack Brown It kinda reminded me of the music from that Drive movie.
I know this video is from three years ago but great explanation of diagnostics!
Super tech hits it again. Great job Eric.
Fantastic diagnostic thought process and a new back up to the Verus when it craps out again :) the best part of the whole vid was the scenic drive just awesome scenery and the best part was when you drove past Opie Taylor's house, next time could you drive past Aunt Bees place.

Yes, I met the whole crew and no with respect to the jam. You're kidding right? More people live on my block in Phoenix than live in Avoca and Bath combined.
