Let us first try to find what is causing the engine not to start; is it lack of compression, spark, fuel pressure or injector pulse? Once we find which of those is missing, we can then focus on diagnosing the corresponding system and pinpointing the problem. Sounds good?

We should start by trying to start the engine with starting fluid; if it starts and runs momentarily, then we'll know compression and spark are good. If that's the case, then we'll need to test fuel pressure and injector pulse - we're looking for about 50 psi fuel pressure and a steady flash from a Noid light for injector pulse.

Please run those tests and get back to me with the results so we can continue.

Best Regards.
