The same thing happened with my old MAF it
almost started but stopped inmediatelly,if
I try severall times it can start but will
stall after some time. If I disconnect the
MAF, it starts OK.
I have checked the ignition system, the
fuel system and the oxigene sensor and
didn`t fynd anything wrong.
Does the ECM box in this cars go bad?
I`m out of ideas......
What do you think?
Thanks

One more thing.I don`t get any codes when
the car finally starts with the MAF connected
and it runs good then, until it stalls after some time.
When I disconnect the MAF I get code 33.
Thanks.

Your old MAF was likely fine. Replace your MAF burnoff and power relays.

 

Do you think the problem is the relays?
consider that I don`t get any code with
the MAF connected
Thanks

Anyone has more answers, please?

Assuming the wiring and connectiuon are goo and intact, then I'd suspect you are getting a burnoff signal while the car is running...hence the suggestion made earlier to replace the relay...in fact, pull the burnoff relay and see if she runs okay.

Don't run it often with the burnoff relay out, or premature MAF failure will occur.

Also, if there is an issue with poor contacts in the MAF relay, it could send the wrong signal to the ECM.

Then there's always the possibility you got a bad MAF as well.
