So I was turning the car over to check if I could hear anything with the relay and it started right up and ran. Left it idle again and it died after a minute or so. I can hear a loud click of a relay in the RCM when I turn it to run and a pump sound under the hood close to the transmission area. When I press on the fuel rail test port it always shoots a little fuel out. I'm still thinking crankshaft sensor. I read it can fail as engine warms up. How are you holding the relay closed? Alligator clip?
