Volvo D6 350 DPH-A Trim/Starting Issue

[1ky]

I am new to this forum and the Volvo D6 350s. I have twin diesel DPH-A engines. I recently pulled it out of storage to change the impellers. This went pretty well considering it was my first set on this type motors. I removed the fuel filters along with a couple water lines during this process. After installing them I first started the sb engine. All was well. I tried the port. Nothing. The port side gauge cycled through all of the warning lamps, stopping on the orange triangle indicating a fault. I cannot find any way to determine a fault code. Whenever the key switch is turned to the start position, there is no sound whatsoever. The triangle continues to flash on port gauge even after key switch is turned off. It will do so until the battery switch is turned off. Also, the tilt/trim does not work at all. With both key switches on I tried holding down the N button and pushing the trim button. Nothing. Batteries are less than a year old and fully charged. Any input will be greatly appreciated.
