klde v6 not starting and backfiring

[jimmyhotrod]

I generally make up a timing scale or disc and attach to the crank pulley. Only needs to be temporary - printed out at home and glued on. Mark a true mechanical TDC and use a timing light to check your spark is actually happening where you think it is.

Hi dave, I did that, I actually made a sticker so it's on my pulley. I then used a dti to find tdc then adjusted my wire pointer to 0 deg.

Wheel on the left is a stock wheel with the outer pulley machined off, wheel on the right is the custom pulley.

Here's where I got the trigger from:

I just scaled it to replicate the same diameter as the stock trigger wheel.

Any update

Certainly not vehicle specific, but I've never seen any engine with a 123456 firing order as you note in your first post. If you are firing like that, I would think that may cause some trouble?

Most all GM 60*v6 engines fire 123456.
Thats a thing you know now.
