Following is a guide to check it, but did you "burp" the system to be sure you don't have air locked in it? With it cold, start it with the radiator cap off. let it isle and warn up. Eventually the air bubble will come out, but be careful, they can splash on you easily. give it time for all of the air to come out. also:
You have to have the car running.
1)Start your car
2)Disconnect the coolant temp sensor (CTS)
3)After about 10 seconds the driverside fan will come on
If the fan doesn't cycle on you have to figure out whether it's a bad CTS, a bad fan or fan relay. If you disconnect the connector leading to the fan you can apply 12volts to one contact and ground to the other and the fan will spin. There may be a diode inside so if it doesn't spin right a way swap the 12v and ground leads and check again.
The CTS is also sensed by the ECU but it generally takes a shorted one to make it fail. One that is 'open' would cause the fan to run all the time.
More apt to be just a bad connection at the fan connector. Clean the contacts with a nail file. Also check the 40amp cooling fan fuse located in the engine compartment fuse block.

I have a1996 mazda 626
Thanks for choosing Fixya and welcome to the site. You need fuel, air, and fire to start your vehicle. Since it starts for a second, you still need to check the fuel pump and filter. Check any fuses/relays to do with the fuel pump. Make sure the timing belt/chain is not broke. It can be spark plugs/coils, wires, distributor, dist.cap, coil packs. You could have a bad cam sensor or crank sensor. It can all lead back to a bad computer. In all honesty, it could be anyone of these. Your best bet, if you have a check engine light on, is trying to get a code of your computer. By doing this, it saves valuable time and money. If you can't, check everything you can cause any of the above can cause this. If you have any questions, feel free to ask. Thanks for using Fixya.
