cranks, but doesn't fire...
hey well thanks, at least now by checking EVERYTHING else I know for sure that all my grounds are good and also where all the ECM harness wires trace out to lol -- threads looked good, so I used a very light duty thread locker to keep this from happening again after I set the sensor properly.- benf8706

ok, so I'm not sure how this is possible but the clamp for the cam sensor wasn't tightened and my buddy was cranking motor over while I was messing with some wires and i accidentally bumped the cam sensor maybe 5* clockwise and it magically fired up... so i stared at it for a minute and rotated...- benf8706

cranks, but doesn't fire...
a good point, but I try not to take any of my vehicles (new or classic) to be fixed at a shop if I can help it - I enjoy learning what there is to know about the vehicle, and having the satisfaction of fixing it myself! I'm just new to these Buicks , and a Buick Mechanic (for reference) is hard...- benf8706

ok pulled the balancer and had a look at the balancer ring - its maaaaybe 1/16" off... I'm wondering if this is enough to cause my trouble? I was almost hoping that the ring was like an inch off so it would explain why it seems like its sparking at the wrong time.. still puzzled- benf8706

thanks for the replies guys-- just checked the wires and swapped out with a module from a running car - still nothing :confused: re-re-checked that the cam sensor is installed correctly (#1 @ TDC on compression) , had a look at the valve positions also everything looked kosher...- benf8706

Thanks for the reply, I'll head out to the garage to make dead sure, set using Cam Sensor Information but I'll check again... previously tried two different cam sensors using this method (one new, one from running car) if that helps at all- benf8706

Ok, got this stock rebuild back together and it just will not run. I have spark, fuel, and compression. Cam sensor has been set, and crank sensor gapped. Every couple of revolutions I get an intake backfire (blew off vaccum hose once), but thats about it... I'm out of ideas at this point, so any...- benf8706

New to Turbo Buicks
Well I'm new to the world of Turbo Buicks, and I was thinking that probably the best way to learn would be to ask the guys that know. I know the basics, and am good mechanics- but like I said I'm not familiar with these cars. Here's what I came into: 87' GN , Bone stock, 116k on motor, 15k...- benf8706
