1994 pont bonn. se after you drive for a bit it might not start again until after 20 min or so. someone said mass air flow or map sensor?
This car will start cold usually but after you drive it for a while and stop for a while it may not start. Keep trying and 15 to 20 min later it will fire up. Someone suggested cleaning mass air flow and if it runs better change the map sensor.
sounds like your crank scensor is going bad.try that first.also dont spray anything through the mass air ,it will be bad.
Yes, there is a special mass air cleaner that you can get, but neither of those issues would cause your problem. I would sooner suspect either a fuel pump/fuel pump relay or ignition module. These can have issues when hot that will not manifest when cold. You can have the ignition module tested by an auto parts store.
I had this same problem with the same car and got the same advice everywhere. Replace the crank sensor replace the ignition module replace the harmonic balancer nothing worked. Ended up being a bad ground. My advice based on this exact same experience would be to take it in have the wiring checked and save yourself weeks of frustration it cost me 150 bucks which was nothing compared to what I spent on the other useless repairs.
