It was on a buddys blazer but it wasnt as loud as that. but it ended up being the o ring around the injector unit and the upper intake plenium not sealing

 

Doesn’t start checked fuel at fuel rail has fuel, checked fuel pump it clicks on, and then I checked spark and have that, debating on checking the fuel injectors seeing if that’s causing it not to start, how would I test this now

 

What year? Perform the sticky fuel pressure test.

Mines an 03 my fuel pump is only a year and a half old I’m hoping it’s not that, but that’d be the easiest, cause I’m not wanting to do the injectors on it
