Hello, if the vehicle has proper fuel pressure, proper spark, and proper compression, then the last thing to check would be the valve timing. However for our purposes, we will need to ensure that there in fact is fuel pressure, spark, and compression. There should be a Schrader valve at the fuel rail. With the ignition on, take a screwdriver or something equally as small to depress the valve with a rag over it to confirm there is fuel shooting out of it under pressure. If the fuel does not shoot out, it is not pressurized and we can pursue a fuel delivery related issue. As for spark you can pull a wire and while cranking the engine verify that spark is indeed occurring, or even better install an in-line spark tester to watch more safely. Compression confirmation will require a compression testing gauge if you have one. Please check these things and report back to us.
