SOURCE: 99 Mazda 626 thermostat replacement

Sure, but you have to be able to handle the contents of the coolant system (roughly 2 gallons) and be prepared to refill it with fresh coolant. To replace it, drain the cooling system first. Remove the top radiator hose from the thermostat housing at the top of the engine. Remove the bolts holding the housing to the engine and then pull the housing up. It may be stuck and you will need to pry it up gently. Do not use a screwdriver under the housing to pry it as you will gouge the metal and cause a leak later. Often a few soft taps from a rubber mallet will loosen it. Note how the thermostat spring is set in the housing as that is the way the new one will go. You will need to remove all of the old gasket material and avoid letting it get dropped into the engine opening. I stuff a shop towel in the opening before I start scraping with a plastic scraper -again this avoids damaging the soft aluminum. Once the old stuff is out, put in the new gasket, put the thermostat in (you will have already bought it and have it on hand) cinch down the bolts to be snug but not overly tight as they can strip easily. Replace the hose (maybe with a new one since you've done the hard part?) and then refill the cooling system and test run to look for leaks. You will need to get the engine up to normal temp to allow the thermostat to begin working. Might as well change all radiator hoses if they are more than 3 years old at this point. Otherwise you will be draining the coolant system again to do it later.

Have fun with it.

SOURCE: Do you know where or if a 2000 Mazda 626 has a

Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC

SOURCE: cranks but won't start fuel pump not coming on

put a small amount of fuel in the intake near the throttle plate then crank and see if it fires, if it does then it's a fuel problem, if it does not fire then pull a plug wire and put a philips head screw driver into the plug wire hold it 1/4 inch away from a good ground then have someone crank it over, you should see spark and it should be blue, if not then you have a ignition problem a bad coil or cam sensor but need to know what you found out on the two tests I told you first to give you a direction to go.

Won't restart after driving awhile

Try cleaning and resetting the throttle body 1st, if its not a dirty air or fuel filter. It might be the fuel pump but cleaning and replacing filters is a cheaper way to eliminate small problems 1st.

99 mazda 626 cut out and won't restart has spark and fuel

When you checked fuel did you check for proper fuel pressure your pump may have pressure but not enough to keep it running. Also Check all your fuses, I had a truck crank and crank I replaced fuel filter etc and come to find out it was just a 5 amp fuse for the ignition

1997 mazda 626 won't start.

Are the plugs wet with fuel?
Check for spark. No spark? it may be the ignition module.

Plugs dry and spark present? No fuel?Spray a little starting fluid and see if it will run on that.
Then check pump fuses and for fuel pump noise.

Have 99 mazda 626 sat idle for a year replaced batterty and alternator belt . cranks but won't start.

I would check to see if the car is getting fuel to the engine. Make sure your fuel pump is kicking on. Check to see if gas is going to the fuel filter from the pump. Make sure gas is going through the pump as well. You could also check the fuel pressure to avoid looking. Make sure it is in range. Also, make sure your battery terminals are cleaned and they are not loose. Make sure all the wires are tight and correct at the alternator. You may have an issue with the ignition system. check for spark. You may have a bad plugs or perhaps, a crank sensor or cam sensor. It could be anyone of these parts. You just need to do the proper test to eliminate all possibilities. If you have a question, just let me know.

My 1998 Mazda 626 is not getting any power to the fuel pump. I currently have straight wires connected so that the car can run but that is only temporary. I want to fix it the right way.

On Many cars, there is an emergency fuel pump disconnect. It is usually located near the front passenger seat, between the seat & door jam. Make sure that it did not get turned off accidentally. Check your owners manual for the exact location of this cutoff switch. There is a 99% chance that this is your problem.

Hi Janieanip01,
Again we need more imfo....Is the vehicle injection?....If it is you'll have to wait until the fuel rail is re-pressurised before it will start....Crank it for about ten seconds at a time so as not to burn out the starter motor....It may be that the vehicle didn't run out of fuel but instead the pump may have given in....and when did you last replace the fuel fiter?
