2003 Mazda PR5 problem starting

Asked by Aug 22, 2010 at 08:39 PM about the 2003 Mazda Protege5

Question type: Maintenance & Repair

I have a 2003 Mazda PR5 that intermittently will not start. Changed battery, battery
cables, and starter, but we're still having the occasional problem of no start. The
car usually starts by the time the tow truck arrives! What do I do?

Do you have any light on currently? CEL/MIL/ABS/EMERG? There is a whole list of what it could be, the fact that it happens intermittently is an odd one but here are 2 options for you, that I feel confident it could be with my history of automotive, and our silly/amazing cars....My first answer is going to be check Cam position sensor, and the Crank Sensor. These sensors can give you an intermittent problem starting your vehicle. Although 90% of the time when they go bad they will send a signal to ECU to trip CEL/MIL. My other idea is that possibly a clutch sensor, or possibly Reverse/Neutral switch in the transmission. Check these out, as there not the hardest to do at home, or with little to no effort. Let me know what you find out, or if you need anymore help. I'm a Toyota Technician, but love my Mazda's

Thundercrack, Did you ever find out the problem? My 03' P5 does the same thing, and before I replace the starter, I thought I'd do some searching. Thanks, myrealtor24_7@yahoo.com

having same problem, but mine doesn't start at all. check the starter relay, positive, battery cable, or there may be a bad cell in your battery. what i need to know is where the starter relay is located...

We are having the same problem of the car not starting about 20% of the time, but when the car won't start in PARK we can put it in NEUTRAL and that will always work. I heard about this problem on car talk, in another type of car, but can't remember what they said the fix was. My mechanic couldn't reproduce the problem, so they said they couldn't fix it. Car talk said something about a switch that needed to be fixed, and eventually it would stop working in NEUTRAL... anyone else have an idea about this?

Hi, I just bought a 2003 mazda P5 and besides the EXTENSIVEE list of engine problems this car has, and if you dont have them yet, just wait, you will, or maybe your suspension problems will force you to sell the car first. It could be the transmission. Mine often sticks in some mystery position between park and reverse, even though from just looking at it you could never tell it wasnt in park. Anyway, this happens and the car won't start so i put the keys in so the power is on, foot on brake and switch all the way down to drive, and then hard back into park and then remove the keys, and when i try to turn it on after that it always works. Something to try, my suggestion is to lose the car, this is likely to be your first problem of many.

You guys might wan't to check your Mass Air Flow Sensor (MAF). My PR5 was having that problem until i replaced it. It's either that or the alternator is going bad.

I have the same issue, but now a mechanic is having problems fighuring it out, he stated its the cable (accelerator cable) but the vehicle had no problems with that, it would jus have to be pushed hard into the corner then into park to light up and sure enough it would start ? id like to know what the fix is
