No. It would cause the check engine light to illuminate and fail an emissions test but it would start and run.
It sure can.
Perhaps, but I would suspect the fuel pressure regulator. It could also be a bad oil sensor as on some models if there is not enough oil pressure the sensor will also act as a fuel cut off switch. Perhaps the oil pressure sensor is failing at a certain temperature range.
No, it has nothing to do with that.
yes
You need three things for the engine to run, compression, fuel and spark. You say you have fuel now check for spark.
Somewhere in the side of the motor is a sensor called the oil pressure sensor. Unscrew that sensor and screw in the line for reading the oil pressure. Start the motor up and get your reading. Compare it to specs.
next time it won't restart, try disconnecting temp sensor
Could be several things, Crank sensor on distributor, bad oil pressure switch, bad computer. If you cycle the key on then off, do you hear the fuel pump run? When you try cranking the engine what is the oil pressure gauge at 350 Vortec engines require 20+ psi oil pressure to trigger the distriuter to fire.
yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.
Many other options. No fuel pressure, broken timing belt, computer malfunction, no spark,
Fuel pressure should be around 40. If the injectors are not getting power it will not start. Start with a crank sensor first.
