Hi,

A crank no start can be a couple of things. The idea that you checked for spark and fuel indicates to me you certainly have a good idea of the possible causes.

First, is the fuel pressure within the manufacturer's specs? I attached the specifications in pic 1 below. If you haven't confirmed that, do so. Here is a link that explains how to check fuel pressure:

If the pressure is within the manufacturer's specs, I need you to try something. See if the engine starts for a couple of seconds using starting fluid. If it does and then stalls, we know it is a fuel-related issue. At that point, we will need to check for an injector pulse to see why fuel isn't entering the engine.sHere is a link that explains how to test for an injector pulse:

Start with this and let me know the results. Also, if it is possible, record the engine cranking and upload it for me to hear.

Take care,

Joe
