Hyundai Repair: 2001 Sonata Quits running, fuel pressure gauge, needlenose pliers

Question
Ok posted before about Sonata and got answer to check timing and fuel Pressure.. Problem Sonata quits running over 1000rpm tow home ..Check things quits running at all//Checked timing belt no bad teeth  but replaced it anyway carefully alining timing marks They were true when took off......Button all back up still no start.. Take off fuel inlet to rail turn engine over fuel will flow into bottle cant check psi now.. I take fuel rail off then squirt some fuel into injector holes .. It will start it for a sec until runs out of fuel... Backfires some at end of fuel... Ok what turns on injectors ?? Seems to me fuel is not makeing thru injectors?? Spark is good checked plugs wires and get spark.. Stumped on what controls injector flow??  No ODBII codes.. Thanks Help!!

Answer
Your engine control module (ECM) controls when the injectors fire.  The fact that the car ran when you put fuel in the holes indicates that you're getting spark.  The things required by the ECM to give spark are pretty much the same things required to give injector pulse.  My suspicion is that your fuel pressure isn't enough to open  the injectors when the ECM energizes them.  

You might look to purchase or borrow a fuel pressure gauge and the adaptors necessary to hook between the fuel pressure hose and the fuel rail.  You should build up pressure of at least 35PSI when running.  If it's lower than that, replace the fuel pump.  While the engine is running, briefly clamp off the return hose with a pair of needlenose pliers.  The pressure should go up to 90 PSI or so.  If it's significantly lower than that, replace the fuel pump.
