no signal from mass air sensor or distributor

Took my truck to get tuned yesterday and theres no signal from the maf or the distributor after the 411 swap. Triple checked my wiring and it was right. Anyone have any idea whats happening?

Check the 20amp Engine 1 fuse.

thanks, it was blew. hopefully thats the only problem. would that also cause the #7 injector to not fire or would that be a problem with the injector itself?

Make sure the Red/Black wire at PCM connector C1-44 is fully seated. If it is then you most likely have a bad injector.
