Hello,
I just change my head gaskets and now I am not getting any oil pressure. Could the oil pump have sludged? Do oil pumps give out? I am in the process of removing the oil pan to check for sludge. Is there an easier method? Any special chemical I can poor to drain after? I also replaced all my fuel injectors about 4 years ago. Every now an then, one keeps on malfunctioning. Why is that? I usually put a bottle of fuel injector cleaner and it goes away. Why does this keep happening?

Usually these cars have a oil sensor that tends to give out, go to kragen or autozone, buy a oil pressure guage and use that for a more accurate reading

and second, stop using the fuel injector cleaner, these cars are notorious for how picky they are, the cleaner will corrode (spell check) your fuel lines, and it probably not the injector being faulty, check the coilpack, they give out alot, also check the PTU
