Timing mark 5.0
I hope this is not too dumb of a question. In checking the timing on my 89 5.0, I see the metal pointer on the timing chain cover. The front of it is like the point of a triangle with the base of triangle going across the crankshaft pully/balancer. But there is also kind of a notch on the metal pointer also, looks kind of "u" shape, like a bottle opener. There are no degree marks on pointer at all. To set timing, line up mark on crankshaft with the flat end of pointer or to the little 'notch'? Thanks.

The degree marks are on the balancer. They likely need to be cleaned, then using a paint stick or liquid paper etc. mark the 10 degree before top dead center on the balancer. Pull the spout connector, connect timing light and start engine. Your line should line up with the long flat edge on the pointer.

I second the use of WhiteOut for that timing mark...makes it nice and clear to see.

Pull the spout connector. It's close to the TFI module and it's a small plug connecting to two yellow wires. Pull this with engine off then start engine. It should now be at 10 degrees. What this does is disconnect the computer from your module effectively stopping any timing advance.

You have to pull the SPOUT connector to check or set the timing. Once the timing is correct you have to re-insert the SPOUT to actually drive the truck.
Pulling the SPOUT disables the PCM controlled portion of the ignition advance, leaving onty the base timing. It is the base timing that you must set with the timing light at 10-14° BTDC. Once the base timing is set and the SPOUT re-installed, you will have increased timing as required by load, RPM and throttle opening.

I can't count how many times I've had to explain that to someone, either on the phone, online, or in person, and have never made myself sound as professional as you just did. That was really outstanding.
Just wanted to say that.
