Question about 1992 Buick Century
Hi there, well if you have a bad fuel injector the easiest way to check is if you have a misfire code come up then pull the spark plug out and with the wire connected to the spark plug, place the plug on metal on the motor and turn the motor over( make sure your wearing gloves when you do this, i wouldnt want you to get shocked) and if the spark plugs are firing then you narrowed it down to a fuel problem. next you can take an ohm meter or light tester and backprobe the pigtail while they are still conected to the injectors to make sure they have power and if they do you really narrowed it down to the injector being faulty or cloged

SOURCE: Fuel injectors leak at fuel rail
Get some new O-rings, and this time put oil on them before you insert them into the fuel rail. The regulator is alright.The problem is that the o-rings can roll up, or twist when push em in dry. Had this problem once, easy fix, but was frustrating.

Bad injectors cannot make plugs bad.
Plugs are cheap compared to injectors.
I've replaced my own plugs, so I cen't tell you the labor to replace them.
If something needs to be fixed you can bet they will charge whatever they can!
