Welcome! My name is ***** ***** I will do my best to assist you with this problem.Ask me about added features such as phone contact anytime if you wish !
when cranking it over the grey shows no volts and the pink is a good ground ?
can you be sure the fuses called SIR/DISPLAYS a 10 amp fuse and the fuse called FUEL SYS CONT MDL a 15 amp fuse are both good and with the key ON both show 12 volts at each of those 2 fuses ?
ok let me know
if they are both good and this happened only after you used the car for a jump start usually this usually means a blown fuse or one of the modules was spiked like the ECM or the fuel pump control module were damaged from that jump start which connecting a scan tool to see which module is not communicating will say which is the bad one or damaged module

Hi my name is***** me see if I can help you find those fuses. They may not be your problem but we do need to check them first. Here is the diagram for the fuse block under the hood showing which fuses to check.
Also I noticed this happened after you jump started your motorcycle. Did the cables get jumped incorrectly perhaps? I know mistakes can happen to anyone so please don't feel as if I'm judging you!
So you put a new fuel pump in the car? Is it still installed, or did you use the old one? It may be that the old fuel pump blew the fuse.
Also how much fuel is in the car? These have known issue with the fuel sender being inaccurate and not having enough fuel. I would suggest a replacement fuel pump with a new fuel sender. Some come with the pump some don't.
