Re: Malibu just died while idling in my driveway...
It originally failed with just the stock GM hei distributor.... I wired in my MSD digital 6 to see if that would help. The digital 6 ignition takes the place of the ignition module inside the HEI... I didn't want to buy a new ignition module, and I already had the digital 6, so i put it in to see if that was the problem. It does the same thing.
as for the dots.... i will explain better. The dot on the cam gear is at the top 12 oclock position when #1 is at TDC and so is the crank gear dot. so to make the dots line up i would have to spin the cam 180* If i spun the crank one full rotation i would be on my exhaust stroke, and thats exactly when the do line up is on my exhaust stroke.... I double checked tonight and all the valve events happen at the right time. right after TDC compression stroke comes the power stroke and no valves open on #1 cyl. then as the piston comes back up the exhaust valve opens, when the piston goes back down the intake valve opens while the exhaust valve closes, and finally when the piston travels up again both valves close for the compression stroke. just seems like the dot is in the wrong place..... and I can't see the chain jumping exactly 180* out while idling in my driveway. This has to be something easy i'm overlooking.
