Re: no spark in fuel injectors
Ok, the P1388 is a failure in the auto shutdown relay control circuit. Also the fact that you have power at fuse #6, but not at fuse #26, shows that the ASD relay is not energized. Did you try and swap this relay first? Just use an other same relay from the PDC, just for trouble shooting purposes. If an other relay fixes the problem, you will have to change the broken relay.
The P0320 code shows that there is a fault in the crank sensor circuit, but i would first see if solving the ASD relay problem will not solve both problems .
