refurbished injectors now car wont run

[TrumpyAl]

The cleaning fluid shouldn’t be left in the injectors too long - if they’d been put back in the car immediately after cleaning then they’d have been ok. They will be fine, but the injector guy will need to ‘unstick’ them - unless you want to try tapping them with the side of a screwdriver. That’s never worked for me, but it has for other mechanics that I used to work with.

The workshop that I used to work in would keep cleaned, used injectors in stock so that we could do a quick changeover and get the injector cleaning guy to do them in batches (cheaper). We learned the downside pretty quickly and the injector guy started adding a few drops of valve seat saver to each injector after the clean (which was a hassle for him so he had to start charging us the full price again).

No one’s fault really, although your mechanic has learned a lesson that it would have been good for you if he’d already learned it in the past.
