Hello!Brian is going on Vacay and asked me to help you.here is how I suggest you proceed here instead of jumping around lets isolate the problem step by step.
Here are the procedures to check for a no start on a fuel injected engine.It will require a couple diagnostic tools that you do nt most likely posess,but may be able to obtain through a tool loan or rental program at many parts stores.
In order for an engine to run it needs the following:
1. Fuel (Fuel pressure gauge)
2. Spark (In line Spark tester)
3. Injector pulse (Noid Lights)
You must determine which one or more is missing to proceed.
You can reduce the troubleshooting by spraying carb clean or a little ether into the intake throttle body to see if it attempts to start.If it does, then there is a problem with fuel delivery and not ignition.This will tell you whether or not there is fuel being delivered and isolate the issue to fuel pressure/delivery or injector control circuits.
FUEL SYSTEM PRESSURE 49 PSI(POUNDS PER SQUARE INCH)
POSITION THE IGNITION SWITCH AND THE A/C SYSTEM IN THE
OFF POSITION. INSTALL A FUEL PRESSURE GAUGE TO THE
VEHICLES FUEL RAIL SERVICE VALVE. CONFIRM THAT
NO LEAKS ARE PRESENT, AND PLACE THE IGNITION SWITCH
IN THE RUN POSITION AND UTILIZE A SCAN TOOL TO
ENERGIZE THE FUEL PUMP. THIS WILL BRING THE SYSTEM
TO A STABILIZED FUEL PRESSURE THAT CAN BE VISUALLY
VERIFIED ON THE GAUGE.
You can check for spark at a spark plug wire while cranking with a flat tip driver or in line spark tester inserted into the plug wire boot and placed close to any metal part on the engine besides the fuel system lines and fittings or just plugged back onto the spark plug if using an inline tester.
To check injector pulse you will need a noid light set which can be purchased at your local parts store or through tool rental or loan programs as mentioned above.(Picture below)
To check for air just make sure the air filter is not totally restricted.
If all is OK check compression at each cyl with pressure gauge as the timing belt may have jumped atooth or broke.
Please post back with your results so that we may help you through you car trouble.
