I bought a Buick Grand National out of a storage unit in this video! The car has been broken for about 10 years, but we take an entire day fixing it on the road and driving it home! Enjoy and let me know in the comments if you’ve ever owned a Turbo Regal!

I think it may be a transmission problem
This was very fun to watch!
Nice job guys!! Sweet ride!!!
Hey Alex, the only reason the car was dying was because you let it die…
I thought you had it after you said you were going to 2 feet drive it!
Also fuel delivery issues
Dying with gm cars is always crank or cam sensors Nissans are bad about it too I have fixed dozens where people had given up on the car and it was the crank or cam sensor
I actually Felt that @9:35 !! Vaccume Leak?
Fuel Pump Assembly is bad
My very first thought was bad fuel….had similar issues myself in the past.
fuel pump & brakes. that's my guess.
Wow, you really do not have a clue about cars do you??? Oil on the sparkplug threads has nothing to do with the condition of the motor!!! You are supposed to oil the threads so they don't seize!!! Grand national with a speedometer that tops out at 75 lol!!!
A gallon of gas isn't gonna do much especially if it's full. It needs fresh gas and long road trip.
I dare to say somebody put something in those cylinders to keep them from rusting. But it could be blow by from it sitting long periods of time then being started then sitting long again etc I have seen it before The rings just need to scrape off the scale and actually be driven. Nothing worse vehicle than setting.
That knock could be the harmonic balancer too. The torque converter could be the culprit as well.
Those ignition modules are “magnavox” style modules. Retro fitting to a more modern “Delco” ignition module and coil packs really helps these out a lot. At least the N/A pre series 1.
Busted flywheel
I'm at the 38 min mark , and I'm going to go out on a limb and say it's the crankshaft sensor
Mmm ahh. It's not a real Grand National. It's a T-Type Regal.
Think you paid 6 grand too much !
Man don't get pulled over with that $16k….the police will take it and you may never see it again. Our laws are ridiculous.
To be honest the fuel filter would of been in my top 3 to replace..dump out all the old fuel as well,since water ends up in the tank really quick from sitting.
Oh my. These turbo Buicks, this and the Riviera are the biggest GRENADES GM ever made (I’m a retired GM Tech). Back in the 80’s I was in retail sales. We had a Riviera T-type with the same power train. It was 4-5 years old and it NEVER EVER ran right. I feel some PTSD coming on watching this video lol. We sold it to 4 different people and it came back every time. It finally started on fire with a very unhappy customer and that was the end of it. I’m only 40 mins in and feel sorry for you guys. The Riv & GN turbos looked amazing! Eventually guys dropped a V-8 in these things. The 70-80’s Jags people did the same. Ours was an 85. Maybe this one has hope, but I seriously doubt it. My advice is to unload this grenade on a greater fool! Looking forward to watching all about this thing, while listening to weird noises from this thing and the inevitable rack time it’s sure to enjoy! Enjoy!! lol 😂
Why does this remind me of the same car that derek from vgg bought in michigan
Harmonic balancer
Change the fuel filter again
Knock sensor probably needs changing
Change the knock sensor
The issue with Grand Nationals is 95% of them all got stolen in the 90s and they are probably the highest vin swapped cars on the planet. you necessarily don't need nothing but a real Grand national title and a Regal to make one. I used to work at a dealership and so many of them that came in for trade ins that turned out to be stolen regals that the owners bought not knowing so they wouldn't even take them in on trade.
Almost the same design size as on commodore vy 2003
FRESH FUEL ADD INJECTOR CLEANERS TOO ROTTEN FUEL THESE DAYS RUIN EVERYTHING IF LEFT FOR A LONG TIME
Weldon bit by bit you are tracing, diagnosing the faults, electric plugs contacts, brittle , overheated relays, cables
You need to check each vaccum line, pipes, these are criticals making car rattling idle control issue, vaccum leaks disturb many function.
Check the flexplate for that Knocking noise a cracked flex play will sound like that
It's a fuel issue ..swap the filter
Even if fuel pressure is good, did you confirm fuel FLOW?
That engine does not sound good that knock sounds horrible.
Sounds like really bad gas to me
