My low oil light comes on while trying to crank my car and car stalls; will not start until I keep trying a couple of times. After it starts it runs fine and then shuts off after backfiring sometimes and wont start until a couple of mins.

I have already replaced fuel pump, wires & plugs, fuel filter, and throttle position sensor. I have already replaced fuel pump, wires & plugs, fuel filter, and throttle position sensor.

I don't know which engine, but it may be variable valve timing (VVT) which is dependant on oil pressure which could cause backfire.check oil level, change oil and filter with correct oil. If possible put a mechanical guage with T to current sensor to test pressure when starting so you can watch how fast it comes up to pressure. a cheaper test, and ignore all the flames and negative comments, put in STP while hot, drive a while, then see how it does the next week.
