Engine starts up and after 1-5 minutes the engine will stall
I have replace the fuel pump,Fuel filter, Coil Packs, Crank sensor, Idle Air Control,Wires,plugs,Altenator, Cut the cadillac converter off, Some one told me when you remove the oxygen sensor and leave it plugged in you should not have any more then 1 Psi thru sensor hole so I cut it off the converter and had the same stalled engine. The only thing that I can think of is the ECM? Where is it located? Will it cause this problem?

If your car stalled while you were driving it, look for an obvious reason first. Check to make sure you have fuel in the tank (if your gas gauge is working). Do not sit there and crank the car over, trying to get it to start, as you will quickly wear down the battery if it's not already bad. Check the probable causes for this kind of problems:- Ignition The ignition system is composed of: ignition switch, neutral safety switch, security bypass, plugs, wires (if applicable) and a coil, or in the case of coil-over systems, many coils. The ignition is also tied into the computer. The crank and cam sensors tell the engine where top dead center is. Though these sensors do not usually cause a no start, if they break, the computer will go into "limp home mode," which allows you to get the car to a service station. The car will run badly, and may stall out on you. If the plug wires, plugs or coils are bad and are causing the engine to misfire, the engine will run rough. This may also cause the car to stall when driving. Generally, it will start back up, but it may be difficult to keep the car running. Fuel The fuel system is composed of a fuel pump, fuel filters, and fuel injectors or a carburetor. Some cars have a throttle body---this looks similar to a carburetor and has only one or two fuel injectors in the middle of it. The injectors feed all of the cylinders. In a multi-port system, each cylinder has its own injector. Should the fuel pump go bad, the car will stall while you are driving, as no fuel is getting pumped up to the engine. Bad injectors in a multi-port system will make the car run rough, which can cause a stalling situation, but generally, the car will restart. Other Problems There are other problems that can make a car stall---in the ignition system, the fuel system or in the drivetrain. If the timing belt breaks, the car will stall. If the computer itself stops working, the car will stall. Neither item will allow a car to start back up until it is repaired.All vehicles have an idle air motor or valve. The idle air is governed by the computer and changes the idle. When you turn on the air compressor, you use some engine resources. This makes the idle speed on the engine drop. The computer senses this drop and sends information to the idle air to turn up the idle so the car does not stall. If this part breaks, when you slow down to a stop or to turn a corner, the car may stall. Because the running of a vehicle is complicated, there are many more things that can cause a vehicle to stall. These are the most common things that can cause a car to stall. Other things include wiring, fuses, relays, other sensors not working properly or at all, a bad alternator or a bad battery, or an overheating problem, just to name a few.

SOUND LIKE FUEL FILTER STOPPED UP OR FUEL PUMP NOT WORKING.SOON AS CAR STALL OUT CHECK FUEL PRESSURE SHOULD BE 31 - 36 PSI. IF FUEL PUMP NOT WORKING CHECK FUEL PUMP FUSE AND RELAY. CODE SCAN LOOK FOR FAULTY PCM.BEFORE BUYING NEW FUEL PUMP.CODE SCAN ALSO FOR FAULTY EGR VALVE STUCK OPEN.LOOK FOR FAULTY IDLE AIR CONTROL VALVE.CAR LOSING IDLE CONTROL WILL SHUT OFF.
Flel regulator will only affect max fuel pressure only will not cause it to not start. try replacing fuel filter first if still does not get fuel then you need to see if it is fuel related or if you have a spark at the spark plugs, pull off a spark plug boot and put screw driver in it hold 1/4 inch away from bare metal and crank engine if you get a spark then it's fuel relateed if no fuel it can be the crank shaft sensor or the cam shaft sensor. let me know if it has fire.
Your going to have to drop the gas tank to get to the fuel pump, The crank sensor will give you a check engine light on or service engine light on. Good luck and hope this helps. You can go to Auto Zone and pick up the fuel pump and they will have the step by step instructions for you to replace the fuel pump,oh and replace the fuel filter again when you replace the pump. Good luck and hope this helps. The other cause of stalling is the MAP sensor may have gone bad, or the EGR valve may be stuck open from carbon build up, just remove it and clean it out with Carb cleaner. Good luck and hope this helps you get your car running 100% again. Keep me posted be glad to help you save some money.
Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located before the catalytic converter? The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!
If the problem you are having after the engine warms up and you put the transmission in gear and it quits, unplug the torgue converter (overdrive). If the engine runs fine after this, then change your transmission fluid and hook the torgue converter back up and she will run like a champ. I had the same problem.
