Trying to find out if ground wire side of fuel pump relay goes directly to PCM.I dont seem to have a diagram on this car.Cant get relay to turn on the pump.I think when they got fuse panel wet and shorted it out.It did a back feed and got the pcm driver as well

The trigger ground is controlled by the PCM but it only powers for 2 seconds when key is first turned on.

I wouldn't be so quick to condemn the PCM. Just because it's not turning the fuel pump on doesn't mean the computer is to blame and if it is, you need to find what burned it out before putting a new one in. Is it even giving you the 2 second prime?
