#59 of 75 2000 Mazda MPV - Immobilizer
Feb 04, 2010 (10:54 am)
My 2000 MPV is experiencing intermittent starting problems and I suspect that the immobilizer circuit is immediately cutting the ignition once the car starts or is not letting the van start at all. The dash light will either fail to come on for the self-test prior to start, or will come on and stay on; either case will not allow the van to run. Most of the time it runs fine, however, occaisionally I will get stuck somewhere and it can take up to 30 minutes to get started again. Normally the dash lights clear but there are times when the immobilizer light will remain illuminated (and the van runs normally).
I would like any recommendations on troubleshooting. Both keys have been checked and work, so I suspect the van. I've made sure the steering wheel is properly seated, door locks are not stuck, gearshift is seated, etc. I do not know what fuses need to be checked for corrosion, etc. All appear to be good, just don't know which fuses work the immobilizer circuit. Any suggestions are greatly appreciated. Thanks, Rick

I think I am having the same problem with my MPV. After yours sat for a while would it start ok, then if you turned it off and tried to restart it would it not fully start. Also, there seems to be a gassy smell.
#61 of 75 Engine vibration 2003 Mazda MPV
Jun 13, 2010 (1:14 pm)
We have noticed engine vibration when our 2003 MPV (158k kms or ~ 100k miles) is idling at traffic lights or at the parking lot. Vibration would get stronger with longer idling time and the whole van will be shaking.
Took it to the local Canadian Tire store (we are from London, Ontario, Canada) and the techs could not read any codes from the van's computer. Either the van's computer is not working properly or the sensors are not sending out any fault codes.
They replaced the spark plugs and did the engine flush, but the vibration is still there and the tech can feel it while driving. Now they think that the pulley (where timing belt is) is cracked and is going to replace the pulley and the sensor behind the pulley. They are not sure whether this will solve the problem.
Because they cannot read the codes, they are guessing and changing parts they think causing the vibration problem. I did the engine tune up only last month and hence not sure what is the real cause of the vibration issue.
Any help you can provide will be greatly appreciated.
Thanks so much,

I answered over at MPVClub and in another thread here on Edmunds.
#63 of 75 intermittetn problem on 2000 mpz van
Nov 21, 2010 (9:39 pm)
My 2000 mazda MPV is having intermittent starting problem. it would not crank once i while, but sometimes If I hold the ignition key a little bit longer, it would start right away. I just replaced the starter,electronic ignition switch and also cleaned the spade female connector coming from harness assembly and still having intermittent starting problem. I also had my battery checked and they did not find any problem..

I've had a faulty battery check out okay once. May be worth another look.

In my experience what you describe is usually in the circuitry that energizes the starter relay rather than the other things you replaced [except the ignition switch] - at, I am sure, significant expense. There are typically limit switches on the shifter that require an automatic to be in park or neutral or a manual to be in neutral & a manual will also have a clutch switch, requiring it to be depressed [held in]. These are often hard to find & a bother [or costly] to replace. It's usually an 'OEM' part. This is not at all unique to MPV's; my Subaru has been like that since it was nearly new. I just wired a 12 volt relay to energize the starter relay and I control that relay w/a spring-loaded normally off ["momentary on"] switch you can buy from Radio Shack. If it wont start w/the key I just push the switch [w/the ignition 'on'] & it fires right up. Been woking fine for abt 11 years. I've done the same w/many cars over the years. Good luck.
#66 of 75 2002 MPV Stalling out
Nov 27, 2010 (12:31 pm)
?, My 2002 MPV was driving fine and all of the sudden the battery light would come on then the oil light and then my van would quietly coast to a stop. The thing would quietly lose power. It would start up again fine but do the same thing again. I was running the tank low. I put more gas and it continued to do the same thing. We changed out the fuel relay thinking maybe it is a fuel problem but I'm not sure anymore. Any suggestion would be helpful.

May try cleaning or replacing the idle air control valve. Our 2004 had similar symptoms.
