Question about 1993 Mazda 626
Half the time it wont even start.
Mazda 626 GE 1993 started having problems after I changed the oil filter and replaced the switched that was leaking oil.
After that its been having problems - missing when I accelerated hard(er), needed to do it slow so it wouldnt stop. Now the car only starts 30% of the time.
The problem does feel like its got no fuel, yes there is fuel in the car and have just replaced the fuel filter (thinking that could be the problem) and made sure the fuel pump is working. Also replaced Ignition leads and test for spark. Everything tests Ok!
The car idles fine when running. Is there anything I could of done when changing the switch?
I'm at a loss - please advise.
It sounds like you have ignition problems, inside the distributer there is an electronic module under the rotor button. This module drives/delivers voltage to the igition coil.
I had the same problem and when I replaced this module it fixed the problem.

GM at one time had oil pressure switch wired in conjunction with fuel pump as a safety feature, so that in an accident, engine would quit, oil pressure would drop, thus disconnect fuel pump circuit, thus no fuel would keep running all over during an accident as long as engine was off. Perhaps, although I cannot confirm at this time, Mazda has similar set-up. I'd buy an oil sender directly from mazda, and make sure you install it to proper torque, and try it, or at very least, try another.
