Car will not start but it will crank and sometimes momentarily run and die.
I attached a fuel pressure gauge at the rail side of the hose (not in the return)

Question: when you turn the ignition on (engine not running), does it supposed to be over 60psi?


I also replaced the crankshaft sensor..still will not run. I have AEM ems as my ecu.
Used to run, don't know what happened.
Any idea?

 

Take us back to where it stopped running. I recall you're in a lotus 7 chassis. Can you hear the fuel pump prime? I'm sure you know the aem typically will take a few more rotations before the engine starts. Going to check your other thread for a pic.

 

I have same question here..
