    Thanks Ionel. So the electronic sound made after turning the ignition to ON is the fuel electric pump and not some valves right? I am curious as to what valve is opening up the moment I turn it to ON.

Using all caps makes it sound like you"re shouting...

It sounds like you have either lost your camshaft drive (broken timing chain, or belt, or broken gear(s)), or your camshaft has broken right where the driven end is. In any event, your cam is not turning.

I worked on a Ford van once with gear to gear drive for the cam, but the cam gear was a fiber/resin gear (for quiet running). There was a crank-shaft-gear shaped scoop carved out of the cam gear. Had I not seen that, I would have thought gear-to-gear drives can never fail. Apparently not.

My Rowenta pro precision iron steam station gets hot but doesn't steam. How do I get the iron to produce steam?


There are two cause. One the boiler resistance doesn´t turn of because of snap disc or bimetal thermostat fault or because a coil in the working valve (security valve). But if you can heard a click of opening movement of valve when you push the button it is able to be a thermostat.

Why does my 2006 mitsubishi endeavor limited has problems starting right away?


Hello --
I thought I already replied to this question -- here is a repeat if so, otherwise, please see the bottom addition - Ck
Look for faults in the fuel injection system, Battery terminal connection loose or corroded; faulty fuel pump; excessive moisture on or damage to ignition components; worn/ faulty or incorrectly gaped spark plugs; broken, loose or disconnected wires at the distributor/ coil pack or starting circuit; faulty ignition coil pack..

ADDITION: I know this sounds weird, but you may want to try playing with the gas cap -- open and close the cap when you go to start it. there may be an issue with the cap.. of vapor lock in the fuel tank, also - when was the fuel filter last changed? How about the fuel tank -- have you added any cleaners or water removeal additives (LIKE LUCAS GAS TREATMENT - not the alcohol only additives which only dry out the fuel)?
Best regards
Ck

HAVING PROBLEMS WITH 2001 PONTIAC GRAND AM STARTING. WHEN KEY TURNS, YOU CAN HEAR THE FUEL PUMP PRIME AND IT WILL START; OTHER TIMES, WHEN KEY TURNS, YOU CANNOT HEAR THE FUEL PUMP PRIME AND IT WILL NOT...


  1. Check fuel level in fuel tank, add fuel if empty.
  2. Check battery condition and state of charge. If voltage and load test below specification, charge or replace battery.
  3. Check battery terminal and cable condition and tightness. Clean terminals and replace damaged, worn or corroded cables.
  4. Check fuel delivery system. If fuel is not reaching the fuel injectors, check for a loose electrical connector or defective fuse, relay or fuel pump and replace as necessary.
  5. Engine may have excessive wear or mechanical damage such as low cylinder cranking pressure, a broken camshaft drive system, insufficient valve clearance or bent valves.
  6. Check for fuel contamination such as water in the fuel. During winter months, the water may freeze and cause a fuel restriction. Adding a fuel additive may help, however the fuel system may require draining and purging with fresh fuel.
  7. Check for ignition system failure. Check for loose or shorted wires or damaged ignition system components. Check the spark plugs for excessive wear or incorrect electrode gap. If the problem is worse in wet weather, check for shorts between the spark plugs and the ignition coils.
  8. Check the engine management system for a failed sensor or control module.

Have a rheem furnace/ten yrs old.just replaced thermocoupler and gas valve,furnace will turn on thermocoupler will get red but no heat? whats up?


I know it may sound strange but check to make sure the gas cut-off valve is turned parallel with the gas pipe. If its open, you may have a failed fan proof switch. air pressure from draft induced blower causes the switch to click and open the main gas valve. if this this switch doesn't click(close contacts) the maing as valve will not open to ignite the burners. its a sequence of events that a furnace goes through before it ignites the burner for heat.

Check engine light on and when i turn off the car weird noise coming from engine


I cannot help with the check engine light without knowing what the fault code is, however being you also have a funny noise in the engine compartment the two may be related. If you open the hood after you turn off the cars engine can you locate the source of the noise? I would check the coolant fans first as they can run after you turn off the vehicle.

Backfires and won't start. when ignition is on the fuelpump makes a funny sound.


The fuel pump should engange when ignition is turned on, but then stop after a couple of seconds. This sounds like there is a fault in the fuel system, since the pump does not stop? Maybe a leak somewhere, or some defective valve. I would take it to a decent shop to have it checked, there might be fault codes they can read from the bikes electronic control system.

Gas dryer works, but does not heat


Hello there:
here is a discriptive way of trouble shooting the dryer and it lists the common components that will normally fail if the element has not failed first
Gas Dryer Diagnosticsgasdryerguts.gifThis picture shows the main parts of a gas dryer's burner systemthat can fail. Understanding each component and it's failure mode canreally help diagnose a problem with a gas dryer.
Ignitor failure: The drum turns but the igniter doesn't glow, thereis no clacking sound as the gas valves open and there is no flameignition sound.
Radiant Sensor failure: The drum turns but the igniter doesn't glow,there is no clacking sound as the gas valves open and there is no flameignition sound.
Gas Valve Solenoid failure: The drum turns and the igniter glows andgets turned off but there is no clacking sound as the gas valves openand there is no flame ignition sound.
And another component failure to be aware of, but that's not shown here, is the operating thermostat:
Operating Thermostat failure: The drum turns but the igniter doesn'tglow, the gas valves don't open (there is no clacking sound) and thereis no flame ignition sound.
And here's a picture of other components to ohm out if you're getting no heating at all:
