When I press the gas my truck dies?
The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention. In most late model cars, this problem will usually trigger the Check Engine light.
Why wont my engine stay on?
This issue could be caused by an insufficient amount of fuel reaching the combustion chamber. For fuel issues, start by checking the fuel pressure. With too much air in the engine after the MAF sensor, the engine runs so lean it can’t properly combust the fuel air mixture, and it stops operation.
Why is my truck stalling when I accelerate?
It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating?

How does the cold start injector work on a Toyota?
The cold start injector most certainly works at temperatures above 32deg. The cold start injector time switch provides a ground circuit for the injector that allows the injector to spray fuel during cranking to help start the engine. The time it allows the fuel to spray is based on what the temperature is.
How does a fuel pressure regulator work on a Toyota?
As soon as the key moves to the run position there is no longer a power supply to the injector. The fuel pressure regulator is a spring loaded valve that allows fuel to return to the tank once the set pressure is reached.
Why does my Toyota Prius keep hard starting?
Well, after doing a lot of thinking i finally figured out my OUT OF THE BLUE HARD STARTING. It was my Fuel Pressure Regulator. At first i thought it was my ignition coil because the hard starting was intermittent and i ran a test on it and the Primary Resistance was way off spec, but the Secondary Resistance was spot on.
What happens when the fuel regulator is stuck?
If the regulator is stuck open, it just pours fuel down the return line, right back into the tank, with no or low fuel pressure. ..and maximum pressure when it’s closed — no vacuum to diaphragm; what you should get when starting. Thank you for posting your fix.
