crank but don't start Hi, i'm swaping a 5.3 from a silverado in my 2000 sonoma. But we have a problem. we plug all the harness, fuel pump, injector.. when we put the key at on the security light turn on, went we turn to the other step the engine crank but didn't make any fire. I think it because i don't have the key that goes with the computer. i want to know what do you think about that and if you know how to bypass the chip key?

I have the same problem with my camaro. My problem is the fuel pump. Turn the key and listen for the pump if you haven't already. If it's not that, you may have a fuel return system problem, check that if you have one. Other than that I don't know what the problem is.
