P0320 MAZDA -

Question

I have a 1999 Mazda b4000, 4.0 with a code p0320.the truck will not start unless I unplug the radio noise suppression capacitor

Answer 1

P0320 Ignition distributor engine speed input circuit malfunction

If you removed the radio suppressor capacitor,then you found the problem,a shorted capacitor will affect  the PIP (profile ignition pickup)

Comments

After replacing the capacitor it ran fine for awhile now its not wanting to start again. When it does start it will run fine for a bit then just die. Sometimes it will start up right away sometimes it won't start. The check engine light has not came back on yet. Could it be the coil?
