There is no cranking signal to the computer first check all fusses and make sure when the ignition is on that you have a check engine lite on the dash that lights up when the key is on then you need to check for a signal out of the crank sensor if you do have it then you have to check it at the computer next a fast way to tell if the computer is getting a cranking signal is to turn the key on fuel pump relay will prime the system do not turn the key off and exit the fuel from your gauge into a can so there is no pressure showing on the gauge as long as you did not turn the key off now crank the engine if fuel pressure comes back then the computer is seeing a cranking signal
