stalling engine sounds sick Reply #31 – April 19, 2015, 10:59:35 PM Fuel pressure gauges are available in auto parts stores in the US, don't know about UK. I think the fuel pressure valve is a standard Schrader valve. See if a valve cap from a tire will fit.That part number you listed looks like it is from the Ford Shop Manuals. Do you have the shop manuals?I suggest you get a compression tester as well if you don't have one and check the compression.Does the exhaust smoke? If so what color?Have you checked or replaced any ignition parts? Cap, rotor, wires or plugs.What do the plugs look like? Tan is good. White is bad. Black is bad. Oil soaked is bad.Does spiting when you let off the throttle mean it is backfiring? If so is it through the exhaust or the CFI.Did you adjust the timing? If so, how far off was it? Did you disconnect the SPOUT wire when you checked timing?Have you ever replaced the fuel filter? Quote Selected
stalling engine sounds sick Reply #32 – April 20, 2015, 03:53:28 PM i only got codes for 02 sensors when the engine stalled before the test finish.pass codes when it finished.new cap,rotor,wires and plugs.fuel filter i changed first as it does feel like its hunting for fuel.on that note after 12hours standing opened the schrader valve got a dribble of fuel turned ingnition on got a splurt .with engine runnnig got a stream of fuel was expecting high pressure blast does this sound right?.the backfire is in the exhaust more of a putt or spit.timming was spot on and schrader is the same as tire valve cap.plugs where black.all the fuel pressure testers say for modern schradar valve but not what size it is.

If so, give us a summary of everything you have you have done and any changes to the symptoms. Quote after 12hours standing opened the schrader valve got a dribble of fuel turned ingnition on got a splurt .with engine runnnig got a stream of fuel was expecting high pressure blast does this sound right? That's good. Hard to gauge the pressure like that. Quote Selected

stalling engine sounds sick Reply #35 – April 21, 2015, 08:20:48 AM Two other things that came to mind-1) If it's a CFI, can you see the injector spray when you turn the key forward (you'll need somebody to turn the key while you look)? I wonder if you have a defective or plugged-up injector, or a bad fuel pressure regulator.2) Did the car burn oil? I ask because that can plug up the catalytic converter. The converter can also break apart inside and restrict the exhaust. You could probably test this by disconnecting the exhaust from the exhaust manifold, or pulling the 02 sensor and leaving the hole open. Normally restricted exhaust doesn't make it hard to start though. I only wonder about that because of the "wooshing" noise you describe, and the original EGR and "excessive backpressure" codes you had initially. It's worth a look if you run out of easy things to try. Quote Selected

stalling engine sounds sick Reply #39 – April 21, 2015, 03:07:44 PM How many miles/kilometers are on the clock? If it is high I would almost suspect a timing chain that has started to stretch and has finally produced enough slack that its like being almost a tooth off on the distributor. Pretty easy to check if you can get a wrench on the crank pulley center bolt and can roll the motor clockwise and counter clockwise. You need to be able to watch the rotor in the distributor move while you turn the crank bolt or have someone else watching it. Turn the crank bolt one direction until the distributor rotor moves then stop and make a mark on the harmonic damper at the timing indicator. Now rotate the crank bolt the opposite direction and when the distributor rotor starts to move stop turning the crank and mark the harmonic damper at the timing indicator. This will give you the number of degrees of slack the timing chain has in it. Ideally I believe it should be less than 5 degrees of slack but from what I have read and experienced the motor will run with up to 15 degrees of slack in the chain albeit not so well.Hopefully it is something easy like what you are currently diagnosing but replacing a timing chain is pretty straight forward. The only reason I am suggesting this is the backfiring issue coupled with the idling issues. When it runs does it have good power or is it sluggish?Darren Quote Selected
stalling engine sounds sick Reply #40 – April 21, 2015, 03:59:32 PM it has 146000 on the clock when i first got it under gas never responded as well as i think it should its hard to keep up with the traffic will check for slack in the chain when i get home from work. Quote Selected
stalling engine sounds sick Reply #41 – April 24, 2015, 01:14:19 PM just checked for slack in the timing chain got 10-11 degrees slack will change it next month when i got time.removed o2 sensors no change so cats are not blocked.fuel pressure first test was ok second test i let the engine run for a few mins and the pressure slowly dropped away so fuel pump or regulator?.also is there a de-cat exhaust section available as i can have up to 3.5%co on test thats if it will below that amount.

stalling engine sounds sick Reply #42 – May 09, 2015, 08:06:04 AM ok just changed the pressure regulator and no change will now have to change the pump .can someone leave details on how to put a feed to the pump so i can drain the tank out.will have to clean it out as when i changed the fuel filter it was full rusty and fine silver particles.
