asked by on August 07, 2017

I have a 94 gmc 350 that won't run it was running great and then the temperature gage went way over 260 and when you turn the key It jumps to 240 and goes really fast back down way past 260 and won't move . The check gage light came on although the radiator is full and just replaced the fuel pump, plugs , wires, and has free oil . If you have any items to help , I'd appreciate it
My car has a manual transmission.
