Question about 2001 Mazda Tribute

1 Answer

Vehicle won't start in cold weather.

Hi,
My 2001 Mazda tribute runs fine when it's mild out but when the temperature drops below 0 degrees it turns over like a top but don't make an offer to start. It seems like it's not getting it's gas. I have replaced all the coils and also a valve sesor for the egr valve because I was told that if there was moisture in it, it would cause this kind of problem but I still have the problem. It is minus 4 out this mourning and the truck will not make an offer again I wonder could it have something to do with the fuel pump and if so why only when it's cold and not any other time?
Thanks
dan

    I'm leaning toward an air sensor or coolant sensor, but need your engine for confirmation. 2.0L or 3.0L? There are sensors that tell the computer what the temperature (ambient or coolant) is for starting & when they act up, they can tell the computer that it's warm out, or engine is already warm, therefore doesn't require much fuel to start. Give minimal fuel to a cold start, and it just won't go. Have you tried removing air intake at throttle body and spraying a good shot of WD-40 into throttle body, with plate open , then try starting when cold, just to see if it will fire momentarily? Do you hear fuel pump cycle when you turn key on cold mornings?

SOURCE: 2002 egr valve problems

That would be exactly what I would look for... When the catalytic honeycombs become blocked, it causes a build-up of exhaust pressure... and this restriction in the exhaust will also have a very definite effect on engine performance: The typical symptoms are an engine that initially seems to running okay, but slowly loses power.. in severe cases it will lose power to the point the engine stalls and will not restart until the pressure build up bleeds off.

Good luck with the problem --- it sounds like you are on the right track. And don't forget to rate my advice: your approval is my "paycheck"!

Thanks!

SOURCE: 2001 MAZDA TRIBUTE COLD STARTING PROBLEM

My wifes car had this same problem at about 100000 miles and after many trips to the shop it turned out to be carbor build up in the intake manifold. A fuel injector cleaner was hooked up and it helped the problem, but did not completely solve it. In oreder to get it totally clean the intake had to be removed and clean it out manually.

SOURCE: TRIBUTE TURNS OFF

suprisingly it could be the TCC Solenoid on ur transmission. it could be locked in a gear and when u go to change the gear it stalls out. sooner or later the clutch in the auto transmission will let go and allow you to move. its a long shot. does this happen after a dead cold start or have u been running the car for a while?

if you have a cylinder 4 miss fire it is more likely to be the coil and not the injector. I have replaced a ton of coils on these for miss fires but don't think I've done an injector for this problem yet.

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

Engine broke due to low temperature


The water expands up to more than 9% when it freeze below 0 degrees Celsius. Due to this phenomena, during the extreme cold weather when the ambient temperature falls below 0 degrees the cylinder blocks of the automotive engines often burst or crack badly.
This damage can be prevented by using the antifreeze coolant in the cooling system.

2001 Dodge Stratus, new battery, turns over well and runs fine in temperatures above 20 Degrees. Below that, the motor spins but the car does not start until everything warms up. The antifreez/coolent is...


Your coolant sensor may be stuck in advanced timing mode. Change it & the engine will start easy in cold & warm weather. The sensor is located near the thermostat housing. Remove the electrical connector & unscrew the sensor. Replace but do not over tighten, 5ft. lbs. Top off any antifreese loss. Good luck!
