I have a 91 chev. cavalier 3.1 air,the cooling fan runs constant,I have unplugged the relay still runs, I unplug the coolant temp sensor still runs unplug both and it still runs, is it possible the ac pressure sensor is bad? what could this be, And I do have a second question same vehicle thanks to your site I found my no start condition was due to a faulty injector, I replaced the faulty and have a missfire not sure if I have another bad injector or something else,have rechecked all tests again, and everything checks good,I am thinking of a possible second injector,since my injectors and fuel rail are located under my plenum they are very difficult to access, any help on these 2 problems would be greatly appreciated.before these problems arose the car ran awesome.
