Buick Enclave Won't Start – How to Diagnose Electrical Problems #buick #won'tstart #alternator

Hey Good People,

One of my customers had his 2008 Buick Enclave towed into the shop because it wouldn’t start. I get a lot of no-start diagnostics and have my procedure of different steps I take to pinpoint the problem. In this video, I show you my process and was able to go right to the problem. Spoiler Alert: It was the alternator.

I hope you are able to learn something from this video, or I hope it helps you in anyway. Because that is always the goal.

Your favorite mechanic,
Alex

looking at buying a 08 enclave tomorrow. the car won't turnover and no clicking when turning the key according to the seller. I am curious did this particular vehicle have a no turnover no click or start? I see that your wife asked but you didn't answer.

My 2010 enclave started to show stabilitrak off and service break system with the red break light on the dash. Now my car won’t turn on. I read that it might be my alternator. Opinion?

Jesus Hernandez says:

Yo have to press the brake to start it, rookie

Ive been binge watching DIY videos for the last 48hrs. Literally!! 3 days ago I purchase a used 2008 enclave (private party) and 24hrs later engine light turned on and car died 20 min later. Leaving me and my stranded on a red light. Car sounds like it wants to start but it wont. I hope this video helps.

Hi I need your help please, I got a 2008 Buick Enclave with a 3.6 engine. It was driving fine, but out of nowhere, while pulling the driveway to park the car, it died on me. The vehicle had been maintained with oil changes every 5K miles. I thought it was security system as I got a new key cut but I used the original one and it cranks but no start. Then I thought it might be a fuel pump but I can hear the bump priming and I tested the fuel rail pressure, and it was 50-52. I did scan the car before I took the battery for replacement, and I can share the scan report. I checked/swapped fuses and relays under the hood, and nothing was wrong. I am asking your help and guidance to figure out why the car is not starting, please. Thank you in advance.

That alternator is from the junk yard. It's got the stripe on it.

Paulina Sandoval says:

Where the link to buy this off Amazon?

Leonard Cole says:

Yeah, man. Electrical is like a puzzle. When you push a button power is supposed to go somewhere and if it doesn’t, finding out where it does go is the big problem. Either it’s supposed to go through that switch and it doesn’t or it’s not supposed to and it does.

Always remember, guys, unhook the battery and test with a meter. Electrons want to take the easiest path to ground and if you touch something hot, that path will be you. Meters don’t have enough power to hurt you, but if you don’t disconnect your battery, you’re gonna have a bad day.

Ethan Bernstein says:

Hi Alex, I have a VW Golf MK7 GTI, recently sent the car in for Turbo refurbishment, although the mechanic said the job was done, I still see oil leakage. Could this be that the job wasn't actually done I'm really confused.

Lorenz O says:

Good morning Alex!

Right now im on Test 4

Turn the ignition off.

Disconnect the Fuel Injector harness connector.

Disconnect the Powertrain Control Module (PCM) harness connector.

Measure the resistance of the fuel injector driver circuit between the fuel injector harness connector and the PCM harness connector.

Is the resistance below 5.0 ohms?

If yes, go to Test 5. If no repair the open in the fuel injector driver circuit.

Test 5
Turn the ignition off

Disconnect the fuel injector harness connector.

Disconnect the PCM harness connector.

Measure the resistance between ground and the fuel injector driver circuit in the fuel injector harness connector.

Is the resistance below 100 k/ohms?

If yes, repair the short to ground in the fuel injector driver circuit. If no, go to next step.

Are you able to show me how to do Test 4 and Test 5 please?
