I have a 91 s15 Jimmy and I get an error 2.4 when I do a diagnostic. It says that I am have a computer failure. The speed odometer doesn't work the ABS light stays on and the Brake light. The mileage doesnt update. Do I need to buy a whole new gauge cluster or a new computer module. Or is there a simple fix like a fuse or a connection I need to fix? If it is a whole onboard computer problem how do I change it?

Also, how do you relieve the fuel pressure for a EFI system. I want to change the in line fule filter.
