If the car is starting I would tend to believe there is a fuel related issue. There is an easy way to check for fuel pressure at the fuel injection service port. On some cars it may be tricky to find, so consult your Chiltons or other service manual to find it. Most autoparts stores will allow rent/barrow a fuel pressure gauge. Most fuel injected cars require a minimum of 40psi to activate the fuel injectors even if the ECU triggering them. There is also a test light that you be able to purchase at the parts store that can be connected to the fuel injector connection and it will flash to indicate that the ECU is triggering it.
Good luck.

200e chevy tahoe sputtered shut down while driven on turnpike after getn gas started back up few minutes later thot it was bad gas what else could be problem


It could be the fuel pump. The pump is in the gas tank. The pump is actually cooled by the fuel. Occasionally, in hot weather, when the pump starts to get old, if you run the fuel tank very low, the pump will heat up. Then, when refueling, you are putting fuel in the vehicle that comes from underground at about 50 degrees F. This can cause the pump to fail.

Sounds like the fuel pump is going bad(or in this case,has gone bad). I suggest that you change the fuel pump and use a fuel cleaner in your gas tank as dirty gas may have caused the problem to begin with.

I have an 1997 tahoe and fuel pump went out replaced pump and filter and still won't start. gas is up on the rail at 45psi but not getting to the injectors


This truck requires 51-56 PSI fuel pressure before it will start.You may have gotten a bad fuel pump.

It will not start with low fuel pressure. Buy a bottle of quik start and spray a little bit into the throttle body (JUST A LITTLE BIT ) if it starts and stays running you have a bad fuel pump or a clogged filter. It is no reccommended to use quik start so only do this once or twice then repair the problem.
