Have you checked for spark first? Sometimes a car won't start due to no spark. This condition is usually caused by: Security system, bad ignition module, crankshaft sensor, camshaft sensor. You check it by pulling a plug wire and putting a screwdriver in the wire to see if it arcs. If it is getting fire look for the fuel pressure release valve usually located on the fuel rail, looks like a tire valve stem. If it shoots out gas, and you hear the fuel pump prime, check the fuel pressure regulator. It could also be the timing. There are four things needed for a car to start: fuel, spark, timing, compression. As for your question, as far as I know there is one fuel pump, you have to drop the tank to fix it. Hope this helps.
Have you measured the compression? Very low compression can be the reason. And the reason for low compression can vary - broken compression ring, worn valve/valve seat... You are sure you are getting a spark, just before the spark plug, right? Have you checked the timing of ignition?
we had a hyundai once, that stopped and started for no apparent reason , after much looking at and mechanics it turned out to be some butterfly or non return valves leading from the fuel pump to the engine. they were closing up and stopping fuel from passing through , might be the same kind of thing . hope this helps
