    The first step is to check the operation of the engine computer, when you turn the key on you should see the check engine light illuminate also called the MIL. If it lights up with the key on this is a sign of the engine computer is receiving power. You need to have access to a computer scanner or code reader to scan the computer on this model. Depending on what you see on the scanner will determine the next step.

First check fuses and relays that relate to issue. Then check for fuel delivery. If fuel delivery is present, the fuel pressure to make sure it is within spec from manufacturer. Then check for spark. It takes to two tango. You need fuel and spark to tango. Without one other or the other car will not start.

How to replace Closed Loop Fuel Control?


You don't mention make, model or year. There is no separate Closed Loop Fuel Control that I'm aware of in any model. The term 'closed loop' means that the ECM/PCM/ECU is controlling fuel delivery and spark based in part on information received from sensors in the exhaust system (to keep emissions at a minimum). 'Open loop' means the same ECM/PCM/ECU is controlling fuel delivery and spark based on preprogrammed values depending on inputs from other sensors - engine temperature (cold), throttle position (wide open), etc. There is only one fuel control, it just works in two different modes.

What controls fuel delivery to cylinders on 2000 ford explorer mine instantly fouls all spark plugs


Each cylinder has its own fuel injector. If the pin hole size orifices that deliver fuel into the cylinder are gummed up or have deposits in or on them, then the fuel will be introduced into the cylinder as a stream or other unacceptable spray patterns instead of a conical shape. Chevron Techron is an excellent product that really works to clean fuel systems and injectors.

You may also have defective injectors, worn spark plugs, (they may have improper gaps), the wrong spark plugs for your engine, insufficient spark due to defective coils or the coil pack, spark plug wires that have lost their conductive integrity or a fuel pressure issue.
Good luck.

Engine valve timing


This is a simple engine to work on. Check for compression in the dead cylinder. If low or none, you found your problem....likely burnt exhaust valve.
If compression good, check injector for fuel spay or fuel delivery head for fuel delivery. With engine idling, crack each line nut at the fuel distributor and see if any fuel squirts out.

If so, check spark delivery by pulling lead to dead cylinder and install used/spare spark plug into plug lead. lay this against engine and run engine watching for spark at plug tip. Do not touch the plug or wire while engine running.

If no spark, check distributor cap for cracks inside. The electronics are primative on these so the above should get you close to the reason cylinder is not firing.

My 2005 XC70 Volvo has started to cut out when going up hil at highway speeds


Weak spark or worn out plugs will manifest themselves more under heavy throttle operation, but the first thing we think of whenever someone mentions hills is fuel delivery volume, and the first suspect with low fuel delivery volume is the fuel filter. I would replace that filter before looking any further,
If that does not correct the problem, some more in-depth diagnostics of the fuel pump and the rest of the fuel delivery system will be in order.

1997 Jetta GT 2.0 Stopped running,cranks,will not start


Checking for spark is really simple while fuel delivery is more complicated because of the the way it is metered for delivery. On VW's a fuel pump relay is used and a jumper cable connected to relay box. This controls the fuel pump to deliver fuel manually. With a fuel pressure gauge connected to the line from the pump continued withing the system, you assess whether you have correct fuel pressure, maintain it within a specif duration. Electronic fuel injectors do stick or stay open causing very poor or no start condition. Make sure you have fuel delivery since you are positive that spark is present.

Wont start it turns over with full power,, i put new coil, new cap an rotor


Do you have spark? If you do sounds like a fuel delivery issue. Check fuse for fuel pump, you are in a later year and should have an electric fuel pump. If you are getting fuel to the injectors at correct pressure you may need new injectors.

Try starting with starter fluid if it catches that will secure that it is a fuel delivery issue. If it doesnt you probably dont have spark and most likely be an ignition module.

Car wont start


Fuel delivery must be confirmed with a fuel pressure gauge on this vehicle. Disconnecting the fuel line and cranking the engine to see fuel shooting out does not confirm pressure, it only confirms fuel delivery. Remember you need both fuel delivery and pressure. On this vehicle if the psi is off by just one number that's enough to keep it from starting. Also replacing the coil and rotor (as you stated) does not confirm that spark is reaching the plugs. Confirm that both spark and adequate fuel pressure are reaching ALL the spark plugs.
