If the fuel pump is not the problem for my car not starting, could it be the fuel injection or fuel regulator? The car turns over, like it wants to start but it's just not getting enough fuel to start. I have had the fuel pump replaced twice.
It can be the fuel pressure regulator but not likely one fuel injector is causing a no start condition.It can be the fuel pressure regulator but not likely one fuel injector is causing a no start condition.

'pumping' a fuel injected engine is NOT like the old days (like with a carb)-if you hold the petal to the floor, it shuts off the injectors-NO petal, the injectors pulse (and dump fuel to an engine that is slow to start). If you are having hard starting, chances are good you have a flooding condition-leaking injectors, leaking O-rings, a damaged fuel pressure regulator could all be re3asons for your hard starting (and backfiring from a flooded engine). You should try to HOLD the petal to the floor and see if that helps-if it does, you should get the fuel regulator checked, replace the injector o-rings, check fuel pressure and might even need to consider replacing injectors themselves (or having them cleaned).
SOUND LIKE FUEL PUMP.REPLACE FUEL FILTER,CHECK FUEL PRESSURE SHOULD BE 9 -13 PSI. FOR TBI FUEL INJECTION AND 55 - 61 PSI FOR MFI MULTIPORT FUEL INJECTION SYSTEM.
If you car is a mid-1980's or newer it's fuel injected and pumping the pedal has no affect on it starting. A few causes are = clogged fuel filter, intermitent fuel pump activity [ pump, or relay ], faulty fuel pressure regulator, leak in system, etc. If you can hear the fuel pump run when you first turn on the igntion, then look for the filter or regulator problem. If there's a leak in the system then it may get air bound.
First check the fuel pressure regulator, then the distributor. Check the fuel pump relay and also the wire harness underneath the car connecting to the pump.
If the car fired after pouring gas into the engine, then you should check your fuel pump, listen when you turn on the key, if you hear the fuel pump start and stop, then check your fuel pressure, all fuel injected vehicles have fuel pressure regulators, if your fuel pump isnt pushing enough pressure to the regulator the car will not start, and if it does start it wont operate properly, and may even leave you stranded.. If your fuel pressure is low, check the fuel filter, dirty filters restrict pressure, and are ALOT cheeper to replace than a fuel pump!
Assuming it's fuel injected,check your fuses (there is a fuse for the EFI and fuel pump). If the fuse is fine, then the issue is most likely your fuel pump (located in the fuel tank). You can change the fuel regulator (located under the air cleaner unit) but it sounds like a bad fuel pump.
If it's not fuel injected, please post back for other options.

i been having fuel injection troubles myself and seems to me your problem may be your fuel injection pressure regulator,before starting when you turn the key so your dash lights show up and at that same time you should also hear your fuel pump motor spinning which means that its working and sending fuel through so you may have a fault with your regulator,,hope that helps,goodluck.
yes, fuel filter has been replaced.
