I'm experiencing a crank, but no start on my 1996 Cadillac Deville. The car was running previously and it stalled in traffic out of nowhere to which it would no longer start again, I was able to get it towed back home. I checked the fuel pressure when turning the key to the ON position, not START and it goes up to 10psi and then drops to zero within about a second. I am also not receiving any DTC codes pointing me to any issues. From my research I found that 3 of the main problems could be the fuel pump, fuel pressure regulator, or the fuel filter. I am looking for some help and some tips to help me further my investigation into pinpoint what the actual problem could be. Any ideas?
