What to do when your car won’t start?

My car has an automatic transmission. The engine fuel injection on these engine have to have enough fuel pressure to pop the injectors open to get it to start. The system injectors are known to get clogged and stick when cold also. You would first need to check fuel pressure to make sure it is high enough, and replace the fuel pump if it is not.

What to do if your chevr has a hard start?

You would first need to check fuel pressure to make sure it is high enough, and replace the fuel pump if it is not. Then once the proper fuel pressure is achieved, clean the injection system. This may fix the hard start and if not, then the fuel injection spider would need replaced.

Why does my car not start when I put gas in?

Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeatedly The insulation develops small fractures that open when heated and close… My car is not starting; what should I replace?

What causes a bad throttle body cause your car to not start?

The only way a TPS will cause a no-start is if the TPS is busted/stuck, and the TPS is telling the computer that you’ve floored the gas. The computer won’t pulse the injectors, because when you floor the gas (WideOpenThrottle) and crank the engine, the computer goes into “clear flood mode”. What causes a bad throttle body?

Do you have to put gas in the throttle body?

Can a throttle position sensor stop a car from starting?

Similarly, can a throttle position sensor stop a car from starting? The only way a TPS will cause a no-start is if the TPS is busted/stuck, and the TPS is telling the computer that you’ve floored the gas.

Why does my GM 4.3L engine not start?

No Start Condition Basics There are three very basic components that the engine, in your GM vehicle, needs to start and they are: Air, Fuel and Spark. When your 4.3L, 5.0L or 5.7L GM vehicle cranks but does not start, it’s because one of these components is missing from the mix.

How to do throttle body re-Learn Chevy Malibu?

1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light.

How does the throttle plate work on a GM car?

A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position.

What happens when you replace the throttle body?

If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.

What to do if your Vortec won’t start?

Also had a similar issue spin and no start with a 96 Chevy Express Van with the 5.7L. This vehicles issue turned out to be a shorted pink wire in the wiring harness that runs up the passenger side of the block. The vehicle had died while driving several times and wouldn’t start. Then, finally after blowing a couple fuses, would start at all.

Can a car stall with a bad throttle position sensor?

The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.

How is the throttle connected to the accelerator?

In the old days, there used to be a cable that was connected from the throttle to the accelerator. But now in the technological age, the car’s computer controls when the throttle opens and closes by the feedback it gets about the acceleration of the vehicle.

Why does my car stall at low rpm?

The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged.

What should I do if my truck won’t start?

If that brings no joy, a fuel pressure test is probably next. Edit: If you feel lucky, it cold be the fuel pressure regulator too. Not sure if your truck uses one though.

How does the throttle body work in a car?

A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal. As more air flows into the engine, it injects more fuel, thus allowing for more power.

Why does my car engine not want to start?

If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.

What does it mean when your car won’t start unless you give it gas?

The Car Won’t Start Unless I Give it Gas: Diagnose the Issue! Nothing can be more annoying than a car not starting at the beginning of a day! However, if it does start on pumping the gas pedal, you may get a sigh of relief. But this doesn’t mean an end to the problem.

What makes up the throttle body of a car?

The throttle body consists of what is known as a throttle plate, also known as the butterfly valve. This component is very similar to a flap that opens and closes as the accelerator, better known as a gas pedal, is pushed down and released. The throttle plate opens when the gas pedal is pushed down to allow air to enter the engine.

Can a bigger throttle body improve fuel economy?

Upgrading to a bigger throttle body can provide you with a wealth of benefits. With that being said, you should consider making the upgrade sooner rather than later. However, some people only want to improve their vehicle’s fuel economy. If you fit into this category, you should clean the existing throttle body.

When does the throttle plate open and close?

The throttle plate opens when the gas pedal is pushed down to allow air to enter the engine. When the accelerator is released, the throttle plate closes to prevent air from entering the engine. That airflow is pushed into the combustion chamber instead.

Why does my Car Crank but won’t start?

Instead of a throttle cable to the throttle body, the throttle body is electronically controlled by the computer. And the idle is controlled by the computer. Sometimes cleaning these electronic throttle body’s will fix an idle problem, and other times the throttle body requires replacement. Tester 2 Likes George_San_Jose1

What should I do if my engine won’t start?

Not sure if your truck uses one though. But if it does, and it is part of a fuel return system which returns unneeded fuel rail fuel back to the tank, ask your mechanic to remove the vacuum hose connected to it (which goes to the intake manifold) and check for any fuel inside. There shouldn’t be any.

Why is my engine cranking but not starting?

Edit: If you feel lucky, it cold be the fuel pressure regulator too. Not sure if your truck uses one though. But if it does, and it is part of a fuel return system which returns unneeded fuel rail fuel back to the tank, ask your mechanic to remove the vacuum hose connected to it (which goes to the intake manifold) and check for any fuel inside.

What causes the fuel pump to not start?

The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.

Why is my fuel injection system plugged in?

The electric fuel pump installed for a fuel injection system will draw considerable more volume of fuel from your tank than your old system did.

Why does my fuel pump not turn on?

Well getting to start by adding fuel to the throttle body is not going to turn on some special switch that will send a signal to the pump and injectors. I’m sure you probably just have a bad fuel pump that doesn’t have enough pressure or volume to start the truck, but at running speed can keep up.

Why is my Chevy Vortec 4300 V6 leaking fuel?

In the L35 and LF6 engines, the spider injectors are known to leak at the pressure regulator and at the supply and return lines due to a design fault. Outside of leaking fuel onto the exterior of the engine itself, it can cause excess fuel to get sucked into the engine.

Where is the throttle body fuel pump located?

As you’re already aware, the throttle body fuel injection system on your 1987 to 1995 4.3L, 5.0L, or 5.7L pickup (or SUV) uses a low pressure (12 PSI) electric fuel pump located in the gas tank.

Can a bad fuel pump start a GM Spider?
