Mazda mx3 keeps cutting out

Asked by Hol89 Dec 29, 2016 at 05:27 PM about the 1992 Mazda MX-3 2 Dr GS Hatchback

Question type: Maintenance & Repair

I have a problem with my 1992 mazda mx3 1.6
auto. My partner drove to our garage and left it
running for about 10 mins, after this it just died.  It
then wouldn't start again, turned over but would
not fire, so we towed it home and left it over night.
He came out to it the next day and it started first
time but after a while it died but started fine
afterwards. We were told it was the coil pack or
rotary arm, so changed both of these.  But this
didn't fix the problem. We have replaced the spark
plugs and leads and thought this had fixed the
problem but no luck.
Any ideas what it could be? Don't want to keep
replacing parts on a car that is pretty old when so
far we have been wasting out time.
The mazda was also recalled at the start of this
month to have the ignition switch replaced the
problem has been ongoing since the Mazda garage
changed this. Is it possible they have caused this
problem in anyway?

Never replace parts without troubleshooting first otherwise you'll end up spending a lot of money and not fix the problem. First check to see is there's fuel pressure at the throttle body or when no start condition, spray some quick start in throttle body to see if it runs for a bit, if it does, it's fuel related issue. If fuel pressure is ok, check for spark at the spark plugs, if no spark, it's spark related but at least it'll narrow down the problem
