I unfortunately stumbled upon the problem yesterday. We decided to pull the valve covers and have a look at the rocker movement while turning the engine over. Number 6 exhaust rocker barely moved maybe enough to crack the valve open. Popped the intake off removed the rockers and lifters. That...

Ah gotcha thank you for clarifying! I will give that a try tomorrow. Looks like I should beable to get it set by multimeter for now. We're headed back from Buffalo NY (I live in Iowa). Dad just sold his concourse 70 Buick stage 1 car and we agreed to deliver it. I've had some time to research...

After doing some research I now understand what the cam sensors job is. I'm a little skeptical that this could be the issue only because it sounds like when you unplug the cam sensor it should kick the fuel system into batch fire. I did go ahead and snag a spare cam sensor from a friend and...

I'm going to add the tps sensor to my list of things to replace as far as I know it's the original Someone earlier suggested unplugging the cam sensor after the car was running to see if it made a difference. It didnt have any effect. I assume the ignition systems on these are waste spark and...

I finally got a chance work on the car again and confirmed a few things. I swapped ecu and chips out no changed. Did a compression check all cylinders we're 150psi. Confirmed firing order on wires. Did a smoke test on the vac system no leaks. When I pulled the plugs they looked black the car is...

That makes sense a friend of mine had said the same thing. The kit came with the car along with a lot of these other parts.

Thanks guys I really appreciate the help! Ill check the cam sensor tonight and let the car warm up and get some more video. Is the Casper's o2 kit a decent unit? Looks like it's made well.

Wow that's crazy. I'll give it a try. I also have an extra wideband I could hook up to verify.

Also I didn't post this in this thread but these wires are disconnected by the passenger rear head. Are these both ecu grounds or something else?

Thank you! I'll check the cam sensor. Is there tutorial somewhere on how to check it? I've checked the wires but I can check them again and make sure. This is the O2 sensor kit I have it doesn't have a name on it.

It was new when I got the car running again. It's been upgraded to the 4 pin o2 kit I think racetronics offers. Can't remember the brand for sure.

Yup I've had it on the shrader valve.

Tps is .42 and I did check the maf settings in the translator and this maf came off a friend's running car when he went speed density. I'm beginning to think maybe the used fuel pump I put in is having a problem.

I took a video of the scan master at idle and part throttle. It goes through each screen.

Thanks everyone! I know of Keith but never met him before. I haven't heard of the other two. I know a few other turbo buick guys but nobody well enough that I feel good asking for help. It does have fresh gas that's almost exactly when it happened. I had considered maybe the gas was bad but...

Hey Everyone, I'm a newly registered member from Des Moines, IA. I picked up a 1987 Buick Grand National with 86000 miles about a year ago. This car had been sitting for around 15 years. It had been involved in a wreck 2 owners ago. I purchased the car from a close family friend who has been a...

Hey Everyone, I picked up a 1987 Buick Grand National roughly a year ago. This car sat for about 15 years due to an accident. The previous owner who was a family friend had the engine apart doing some maintenance. It received new valve springs, water pump, thermostat, ported the dog house and...
