No compression in gas tank,what could cause this problem?

This truck starts fine and when it reach the normal temperature stalls and I checked the gas tank and there was no pressure to be released,what could cause this problem and I wonder if it has something to do with the no acceleration of the engine?

SOURCE: 318ti M44 acceleration problem

Have someone handy to press the gas pedal for you after the engine has warmed up well; best if driven.

While you listen at the exhaust pipe, have your helper increase the revs slowly and note whether the exhaust note changes to a hiss, instead of the sound of an engine firing.

You may have a decayed catalytic convertor and when they come apart inside, they can clog mufflers and resonators (the second, smaller muffler).

I've had this happen on more than one car and when it happened on a Fiat Strada years ago, since the routing of the system was fairly straight and made of heavier gauge stainless steel, I fired two shots with a .357 magnum into the tailpipe.
Never had another problem with it.

SOURCE: 2001 silverado 6.0 v8 starting problem at mid temperature.

Dennis, So far you have verified your fuel system is working properly and spark test you performed verifies the ignition system is functioning as it should, you have two of the three needed items finished.
The remaining item to verify will be injector pulse. Without the pulse all the fuel pressure and spark in the world won't allow the engine to start. The reason for this step by step diagnosis is to pin point the system causing the problem.
Then next step will be to purchase or borrow a "noid" light that will tell you if the engine control module is sending the correct pulse to the injectors for fuel delivery to the cylinder.
When the engine is cranking during the "no-start" condition, a good injector pulse will "blink" the light.
Your almost there, good luck and let me know.
Regards,

SOURCE: oil pressure high when engine cold. but fine when engine is warm

It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

SOURCE: engine bk firering & lose of compression.

Backfiring after warming up can be from many things.

One that comes to mind is carbon deposits on valves, causing them to not close properly. The carbon deposits would also heat up and then ignite air/fuel mixtures before the spark plug can fire.
Or you would have hot exhaust gasses leaking back into the cylinder on intake and that would ignite the fuel.

Tac gauge fluctuating, and engine running rough on acceleration could be a vacuum leak, do you hear a hissing sound when the engine is running? listen closely under the hood. If you have a vacuum leak you would lose power and your RPM would fluctuate oddly. As for the backfire however, there are probably more than just one problem. Its hard to say for sure.

So please, more details, noises you hear, when exactly everything happens etc.
What speed and RPM the engine begins to bog down at, does it stall? What range is ur tac fluctuating at? anything you can think of, throw it on there.

Hope this helps you

SOURCE: Misfire cylinder 5 2000 dodge dakota

when u press the gas pedal to go this opens the throttle valve, the idle speed of your engine is computer controlled, this is done by the ISC (idle speed control) airbypass valve, these parts get full of gunk and then get a stalling problem at or near idle, clean them by doing the following, if u don't understand the instructions seek help from your friend.
, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Stalls under load


hi,
if the temperature is normal, it means that 2 things can cause your engine to stall:
1- coolant temperature sensor
2- oxygen sensor

if the car is overheated it means that the piston rings are having a problem

The problem may be the engine coolant sensor. If the sensor fails the engine will stop when normal operating temperature is reached . When engine is cold it will start.

1990 Deville 4.5 litre v-8 vacuum present from vacuum line to egr selenoid but no vacuum from egr selenoid to egr valve the car runs fine when cold but runs poorly when warmed to operating temperature.


You will not see any vacuum from the egr solenoid until the engine has reached normal operating temperature and certain other driving conditions have been reached (like throttle position and road speed). If the engine runs rough when warmed up, check the CTS (coolant Temp sensor) when hot and cold and if no fault shows there, start checking input sensors for engine and cam position, engine timing, RPM etc. If the EGR valve was leaking, it is only adding air to the exhaust stream and usually, manually opening the valve and blowing out the seat with compressed air should fix the issue. This can also be an issue with clogged injectors. When the engine is cold, fuel enrichment supplies more then normal fuel amounts to encourage even running. When the engine warms up (normal operating temperature), fuel enrichment mode is turned off. If your injectors are clogged (even if only slightly) fuel starvation will cause rough running. Fuel enrichment overcomes the starvation of clogged injectors. Try adding a propriety injector cleaner to your fuel tank and watch for an improvement. If you do see an improvement, have your injectors cleaned and tested professionally. If you locate any other issues with engine sensors, replace them and ensure the new components are adjusted correctly if required..

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.
