Here are a couple guides that will help with getting us started. We need to check for fuel, spark, and compression and this will cover common things to check.

The most common cause of this is fuel related so we need to start with checking the fuel pressure.

Here is a guide that will help with this.

Once we know what the pressure is we can take the next steps which would be checking for spark. So, we need to remove a plug and hold it against the block while the engine is cranking. Also, take a look at the plugs and make sure they are not damaged or fouled.

Below is a chart that will help with this.

Please run through all this and let us know what you find with this.
