2001 mazda protege has power to injectors but no spark

yes one of the fault codes
toss water on the CAS ..if hot see if the motor fires

signal comes from the ecu
could be faulty fuel pump /relay ?

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.

Have you checked for a strong blue spark at all cylinders? Have you checked the injector circuit? Are the injectors pulsing and putting fuel into the cylinders? Have you checked compression?


All I can think of. No theft security issues, car is not immobilized by that, is it? If all else checks out, maybe the engine computer?

plug gap is 0.044 in.

I hope help you whit this (remember rated this help).

my 2001 mazda protege starts hard, idles low and high at various times (never normal) and it acts as though its going to stall at all times. sparks and wires are changed no help, changed air filter no help. any idea on what to do?

For about the price of a repair manual, u can access repair info at 2 websites:
alldata or eautorepair
check them out, they should have your year available.

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
