car cranks really slow
 

well one problem after another on my daily driven 7...
its a 91 n/a FC... it cranks really slow...
battery is over 12.4 volts
starter is good had it tested at autozone
plugs are good, I have spark
I have fuel and air of course..

any ideas ? ign switch?

You know, funny thing i had the Exact same thing today.. so bad i stupidly ended up flooding the engine. I went through and "adjusted" all the grounds and it seemed to fire right up after a couple hours of sitting.. Was really weird, i thought the batt was dead/weak. Ended up being loose grounds, may still be a potential bad cell in the battery too - i guess ill see.
You?
