Enginr swap

[matt6095]

Looking for some questions I did a 53 swap to a 6.0 gen 3 LS motor they come in a 2000 GMC Sierra 1500 four-wheel drive I replaced the knock sensors crank shaft sensor I have fuel pressure at the injectors but I have no spark all the ground seem to be good any help or tips

So, the 6.0 is out of a '00 Sierra 1500. What was it put into?

Make sure the coil pack harnesses are plugged in all the way and that you have the harness grounds connected. There is also a ground on the back on the cylinder head you want to make sure is hooked up.

He may have a tough time doing that if this is in a '74 Vega ...
