Heads up on injector swap shortcuts causing big problems

I've noticed in my area that more shops are rushing injector replacements without full diagnostics. Last month, we had a truck come in with THREE failed injectors after a quick swap job. The root cause was a contaminated fuel line that NOBODY checked. Now the engine needs a full rebuild. Guys, SLOW down and test everything first, it's cheaper in the long run.

Ugh, that's brutal. It's crazy how skipping the small checks can blow up a whole engine.

Learned that the hard way too lol. We started testing fuel pressure and checking lines after every single injector job. Found a bunch of small problems before they became big ones.

Man, I always thought that was overkill... until we had a comeback. Found a tiny leak in a feed line that would've left someone stranded. Now we catch stuff like weak pumps or stuck regulators every few jobs. It saves so much headache down the road. Changed how I see doing the job right.
