    I have the same problem, doesn't fire. It turns over fine but, often times, it won't fire. If I spray starting fluid into the carb, it will start.

Well, with all that you have changed the only two possible things that are left PCM and the ECM....

Do you have an alarm system on this vehicle? If you purchased this car second hand it may have something that is inhibiting the engine from firing. From what you have told us here that would be where I would start looking.

I really hope this is helpfull

Will crank sensor causes fuel injectors not to fire?

On Multi point fuel injector cars where the sequential actuation of the fuel injectors occur the timing is triggered from the Crank Shaft position sensor.

The cam shaft is an also key sensor providing the crank shaft rotation sequence first or second rotation to provide the complete timing function

Without these two sensors no spark or fuel.

An engine code will be recorded will provide the culprit if one has failed.

Hope this helps.

Wont start. it has injector pulse but no spark

is there power and ground to the coils?

If there is injector pulse than the crank sensor has to be good. Injector pulse and spark are both calculated off from the signal from the crank sensor.

Checking for power and ground to the coils is a good place to start. If that checks out than either there is a wiring issue in between the PCM and the coils or possible the PCM has failed.

Hi! my name is Carlos I Have a Mazda Protege 99

Check the plugs for spark, pull one out and lay it on a metal part with the wire attached,, crank it over and see if it sparks, if yes, then squirt some fuel in the throttle and see if it fires, narrow it down to something. Check the oil, the electrical sensor in the header is an oxygen sensor, it will not effect the engine, If you don't have a spark, pull the coil pack off the old engine and bolt it on the new one. Check it out.

Test: car won't start

does it crank but not start or does it just click like dead battery or starter if it cranks check for spark and fuel pull spark plug wire and insert a screw driver and hold it close to an engine ground and have someone try to crank the engine is there a strong spark and use what is called a noid light it plugs into the plug for the injectors to see if the injectors are pulsing it should blink when you try too too start the engine if you have pulse and spark check for fuel pressure there should be a service port on the fuel rail that looks like a valve stem for a tire sort of youll need a fuel pressure tester if you had no spark or pulse at tthe injectors its most likely either the cam sensor crank sensor or the computor(pcm) if only no spark change the coil if that doesnt work you might need an ignition module but that requires more testing I cant explain here see a technician if no fuel pressure remove fuel filter drain and attemp to blow air through it if you cant its clogged replace and try vehicle if no start still feul pump is bad replace pump .

hope this helped

Mazda protege no start

There can be a misfire too from the cylinders.

An engine that hesitates, stumbles or misfires when accelerating or when it is under load is an engine that is either sucking too much air, not getting enough fuel or misfiring. If the Check Engine Light comes on, you may find any of the following codes:

• P0171, P0174 Lean fuel condition codes
• P0120 to P0124 Throttle position sensor codes
• P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR related codes

If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.

Another common cause is dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your scantool. If the numbers are high, it tells you the engine is running lean and the injectors need cleaning. Treat mild cases with a high quality fuel-injector cleaner additive. Severe cases require professional cleaning equipment.

Also if this sensors apply to your vehicle, camshaft sensor or crankshaft sensor if sensors bad you don't get any spark. Also run a scan on the car.

Good luck and rate this solution, please.

2001 mazda protege has power to injectors but no spark

check and see if they have a ground signal,if they do make sure the power is pulsating when turning it over if not possible cam or crank sensor trouble.needs to be scanned for trouble codes before swapping any parts.also possible pcm failure.good luck hope i helped..

Car has no spark or injector pulse(new ecm,crank sensor)

Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

I cant get spark out of the coil pack

cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.
