97 with a 2.2 5 speed.something piled up,read codes and ended up changing Crank sensor,Cam sensor and eventually computer.Took it to GM to program it.It still won't start and the fuel pump relay has a fast click in it that almost sounds like it's grinding.If I remove it there is a noise from the ABS that sounds like a small door being slammed shut.Also the cooling fan will start sometimes even when the car is cold.

Check for power and ground on terminals 85 and 86. If it's clicking, then you're losing either power or ground. Could possibly be a bad relay too, swap it with another one of the same size.

For the ABS... possibly a ground issue or caused by the voltage spike when the F/P relay is removed. I wouldn't worry about that.

The cooling fan will also come on when the A/C pressure exceeds a certain PSI, so if the defrost is on, that's normal.
