Question about 2003 Mazda MPV

1 Answer

Mazda etude 160ie a/c cuts out after approx 45 min driving.

Followed on line advice. Mechanic changed fuel pump. Said it was getting 'hot.' Replaced cam sensor. Brand new air filter fitted.
Mechanics ran diagnostic test. Cannot pick up a fault.

Car starts easily. Runs well for approx 40min. Starts jerking and then cuts out. After a wait of about 30 minutes, starts again and drives perfectly.

Please advise on next step!!! Am desperate and cannot keep paying for repairs that are NOT helping.

    Mazda etude 160ie a/c cuts out after approx 45 min driving or with stop start driving in traffic. I then remove the fuel hose on the injectors, turn the ignition until a steady fuel stream flows. The engine then starts after say 2 cranks. Further, she is not shy to rev to the red without a miss. I've checked the fuel cap air valve, which may have been causing an airlock. Seems to be in order. This only happens when the car gets really hot.

Could be an electrical part that only fails after getting really hot. Coils and ignition modules are known for this. Unfortunately, these parts cannot be tested for this heat-soak type problems, other than to see if spark quality at the plugs has degraded when failing. One other thought. A bad gas cap which is not allowing air to flow in as gas is used can cause this and that is a cheap part to replace just for grins.

1995 GMC Sierra 350, Truck has been idling rough.Changed spark plugs EGR valve test drove ran little better. Let sit at idle for a few moments, the truck stalled. Now will not start. Any suggestions?


I would think its a fuel problem.
Try changeing the fuel filter and the air filter but just remove that for now .
The filter is in line drivers side under the drivers door area and is not easy to do but not expensive under 10 dollars .
When you get it off and have gas all over you don't smoke .
Take a plastic soda bottle put it over the line comeing from the tank put the key on run not start .This should make the fuel pump pump if an electric pump.The pump is mesaured IN FLOW PRE MIN and its high because it has return line to the tank if its fuel injection.
So if in 10 sec. 4 to 5 ounces out put the pump is vary good .
If not the pump isn't supplying enough fuel to the system
There are other issues like the fuel injection system and the pressure regulator.

What could cause the engine not to stay running after the fuel filter was replaced? Even after fuel pump was replaced?


From remote site, it is hard to tell what is the root cause, and change pump was done in proper order -- you should post the problem before replacing fuel pump.
Here is what I will do, assume you can do a little by yourself.
Changing fuel filter should be easy by disconnect fuel hose (pipe) from the fuel filter . Since ASE mechanic did job in your house, I assume the old fuel filter is still in your hand. Change it back (replace new filter with your older one) to see if your car will work as before. This supposed to be done before replacing the fuel pump.
If older filter works, then you knew the new filter is the root cause. This could be resolved by replacing another new filter. If the problem appear again, leave the new filter in for over night to see if the new filter will work on the next day (you could use exiting new filter to avoid buying another filter, unless you will get a different brand one). If not, the choice is to use older one for a while when trying figure why new filter does not work.

If old filter does not wok either, then something is in forwarding fuel line between fuel filter and fuel ejection system. Then, that section needs to be cleaned. Assume the pressure is measured at connection between forwarding line and fuel filter.

Why does my Honda Accord acts like its runing out of fuel while driving after having a new fuel pump replaced?


Did they properly 'bleed' the fuel lines after fitting the pump??? Also, was the inlet filter on the pump also either changed or cleaned - and re-fitted properly??? If there is air in the system, that can upset some of the sensors which feed the engine ECU.

1999 dodge ram 5.2 runs about thirty miles then stalls after running fine just suddenly loses all power sputters backfires engine stumbling badly. crank it up 4 or 5 hours later runs a little then same...


General advice:After warming up track the problem:sparkplugs (even new can have the ceramic parts broken/cracked /wiring (after warming up the isolation get's soft,can loose spark power)/ignition coil(s) (gets hot,stop runnig),running reach,fuel pump/fuel pump relay.Best guess:fuel pump mallfunction (low pressure) related,fuel filter cloged/water in the fuel/fuel line cloged/chipped. Cheers,hope u figure it out,let the people know.

My 2001 Chevy Cavalier acts like it is not getting gas, a new fuel pump and fuel filter and line was put on and it quit again on me, another fuel pump, spark plugs or points was put on and still will


Check your lines, specifically where your filter housing goes into the fuel tank. I had the same issue and I just had to replace that filter along with a hose. It seems the line somehow got clogged. I hope you find this helpful.

It sounds like the fuel filter may have reached it life time and needs to be replaced. The fuel filter should be replaced every 15,000 miles if not once every year to ensure that the fuel system is running 100%. A dirty fuel filter is the #1 cause of fuel pump failure due to extra heat created to push the gas to the fuel injectors, the other cause is running the gas tank less then 1/4. It's the gas that keep the fuel pump cool and not running hot.
Start with the simple and replace the fuel filter which should be located On all C/K's of this body-type 88-98, the fuel filter is located under the driver's side door inside the frame rail near the crossmember that supports the tail of the transmission. Replace it with AC Delco part GF-626, FRAM part G3727, or other comparable brand corresponding metal bodied filter. You should use a flare-nut wrench for the line fitting and one for the filter fitting. I'm not sure of the size needed for the filter, but the line should be 5/8"
For SFI engines ('96 and later) you need to bleed off the pressure in the line. Locate the pressure test port on the fuel rail under the hood, remove the cap, press valve to relieve line pressure and recap valve. If ground clearance is not high enough to get under vehicle and work, raise it with jack and rest frame on jack stands.
Caution: Fuel in lines and filter will run out once fittings are undone. Use fuel safe container to catch fuel spill.
Take wrenches and hold filter from rotating, while loosening line fittings. Remove Filter from bracket by sliding and manipulating fuel lines for clearance, and slide filter out of bracket.
Reassembly is reverse of disassembly. Tighten fittings snugly. Reconnect battery, turn ignition on (do not start). Pump will make brief whirring sound - less than 5 seconds. Check for leaks. No leaks - good. Now you can drive again.
Hope that helps, keep me posted. Glad to know you got your truck running 100% again soon.
