Timing
Greetings
I own a 99' gmc suburban, 5.7 vortec. 150K. I had the unfortunate experience of learning how cheap the factory intake manifold gaskets are. When it broke, coolant ran out faster than I could put it in. So, changed out the gasket. what a job.
I carefully marked the distributor for reinstallation and when I tried to start it, it cranked but no start. Thinking I did something wrong to the timing, I reset it and double checked the marking etc. As it turned out I also learned how cheap the spider injectors are as well. So I read up on it and upgraded the injectors as well. Turned over and started right up like new. Not throwing any codes, and runs fine.
My question is: Should I still have it scanned to get the timing spot on?

You could try the trial and error method. Just move the dist a couple of degrees at a time. If it seems to run right you must have it pretty close. I think you have 2 deg. either side of perfect before it sets the check engine light.
