Help me diagnose this problem my car just randomly shut off on the way home last Monday. Got the car towed home, i switch the map sensor and the cam sensor and still no start. I currently have a full blown double pumper on my car so i tried switching the pumps to see if one of them died but they are both getting power. I took off the feed and gas comes out as i crank the car, i then took off the return and no gas. Could it be the regulator that's causing the car not to start?

Any suggestions

 

Getting spark?
