I'm working on a '91 Corsica, 3.1. and have two injector questions.

1. what is the trick to remove the injectors from the manifold. the fuel rail is off, I thought the injectors would come out with the rail but no way. Do I just use force?

2 what resistance shold they have? four are 12.4 one is 11.3 and one is 1.5 my quess is 1.5 is trash and 11.3 is maybe, but I can't find any specs.

Thanks
Rich

Spray the injectors with a lube then twist and pull. Its been awhile but I was thinking they were supposed to check out closer to 14 but not sure where I found it out at anymore. One things for sure the 1.5 is certainly dead.

thanks, it worked. Next question, how do I tell if the fuel pressure regulator is bad?

You can smell gas in the vaccum line is one way you can tell that its bad. As for finding the right specs for the injectors get to a library n use ALLDATA online. Just remember to bring a note book so you can write down whats suppose to be what.
