SOURCE: 2001 mazda protege will not 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
SOURCE: timing marks on 1999 mazda protege 1.6 lx
The book is wrong on each cam gear there are two sets of marks "notches align them facing each other in the center of head nevermind "I" and "E" if correct you'll have both of them making one line in the center of both pulleys and the other set of notches will be 45 degrees below. I found this out the hard way just finished with mine for info and tips on mechanics and parts for your ride visit my site at www.godspeedmotorsportsonline.com
SOURCE: 2001 mazda protege keeps stalling
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?

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.

The Code you refer to is P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input). It is a possiblility that because this code is present, this sensor is malfunctioning. If it is malfunctioning, that means the engine needs to "guess" the value that this sensor is responsible for. In most cases when this happens, the engine will go for a value that ensures the car runs. The engine will not try to run smooth or efficently, it will only try to run. It is my guess that if you have the sensor checked and replaced, the problem might be fixed. Please let me know if this answers your question and please rate my response. Thank you
