Check your collision kill switch.most cars with fuel injct have a switch to shut down fuel pump because of fire potential Check your owners manual fpr procedure also in trunk sometimes there is a sticker saying so .if tjis is prob your fuel press at test port will be 0 .
checked it already, I can hear the fuel pump when I turn the key.
Try starting it in neutral. The neutral safety switch may be bad.
did that. it did work.
You need to plug in a scanner. That flashing light is trying to tell you an error code.
