Shrader valve on a 2001 626 Mazda

My car does not want to start as soon as it warms up. I noticed that the check engine light would come on before this happened, but I would get a code of warming, catalytic converter, I assumed it was an 02 sensor. The car is not running and I canno hear the fuel pump when i turn the key (not starting the car), so I am assuming it's my fuel pump. However, I cannot find where the shrader valve is to check to see if this is indeed the problem. Does anyone know where the shrader valve is located on a 2001 mazda 626 or do I need to check the fuel line?

SOURCE: cranks but won't start fuel pump not coming on

put a small amount of fuel in the intake near the throttle plate then crank and see if it fires, if it does then it's a fuel problem, if it does not fire then pull a plug wire and put a philips head screw driver into the plug wire hold it 1/4 inch away from a good ground then have someone crank it over, you should see spark and it should be blue, if not then you have a ignition problem a bad coil or cam sensor but need to know what you found out on the two tests I told you first to give you a direction to go.

SOURCE: Need to replace 2001 Mazda Protege Oxygen Sensor

The front O2 sensor is located at the bottom of the heat shield just before you get to the exhaust. It has a wire connected to it. You will have access to this from the top of the car.You may need a O2 sensor tool that you can borrow from most major auto parts retailer. Disconnect the battery first then unplug the sensor. Using the O2 socket remove the sensor. The sensor should come with a packet of anti seize, apply it to the threads and install it. Plug the sensor back up and connect the battery and you should be done. Good luck.

Wood a bad idle air control valve cause car not to start

No, a bad idle control valve will not cause a "no start" scenario. See below:

"An IAV sometimes may fail, or can become troublesome. This can manifest itself through various problems while driving. Following are a few problems that may be caused by a faulty IAV. A rough running engine can be caused by a faulty IAV. If the valve begins to stick over time, or fails to respond to inputs from the car's computer, it may not properly adjust for engine loads and operating temperatures. If you notice that your car seems to run rough when it starts up, or once it warms up, it may be a good idea to check the IAV.
Sometimes you may notice that your car stalls at a stoplight or anytime you come to a stop. An IAV that isn't working correctly can cause that to happen because the engine's computer can no longer keep the engine idling. Many other things can cause stalls, so be sure to investigate other possibilities, such as bad spark plugs.
A failing IAV may cause the check engine light or service engine soon light to come on. Because the IAV plays a role in emissions control, if the valve fails it may cause problems with the engine's emissions control system. You can plug a scanner into vehicles equipped with an OBD II port for a quick diagnostic of the car's check engine light issue."

Engine light on, vehicle usually won't start. engine light code is o2 sensor

The oxygen sensor won't stop it from cranking or starting

Check for spark or injector pulse when cranking

Car will always turn over, but will not start on certain days. At first i thought it could be due to dampness and faulty wireing. When it does start it runs smooth. The other day it started in the rain....

next ime you dont start there should be a fuel tester shrader valve just like the tire shrader valve crank it and if it doesnt start check the fuel shrader valve see how much fuel comes out and if it dribbles you need a fuel pump and filter. also the 1989 are populat for intermittent due to the ICM recieving low signals, and the theory back then was what went out first spark or fuel. ICM and cam sensor and crank sensor was just replaced, Now that was the fuel injected part, 1989 there was still carburator that was being made at that time and the popular breakdown was fuel filter getting plugged.

Car start's but as soon as it gets warm it shuts down like it isn't getting any fuel

check for an EGR valve with a leaky vacuum diaphragm. this valve is only assigned to work when the engine is warm. When called upon, the leaky vacuum diaphragm lets in too much air and the engine leans out and dies.

How to remove and inspect throttle body on 1992 mazda miata

Things that make your engine do what it is doing.

1. Vacuum leak
2. EGR valve

Find the vacuum leak if there is one.. and check the function of your EGR valve.

A functioning EGR valve with an ORAL vacuum line suction test will cause the engine to stall / die when suction is applied to the ORAL external line.

Even if it passes the ORAL test... it can still have carbon build inside the plumbing that does not allow the seating pin to fully seat and the engine will surge or be hard to start when warm.

So check / listen carefully for vacuum leaks and check the EGR valve.
