no fire
when my 93 cavalier 2.2 liter runs for awhile it is hard to start,i pulled a plug wire and thier was no fire at the plug,i know the coil packs are fint and ignition module is ok,it was replaced new is thier a relay or low oil pressure switch that could be causing the electronics to shut down ?

Re: no fire
The crank sensor is my guess. The oil light is wired into the fuel system, and will disable the fuel pump if no oil pressure is present. It has no effect on spark.

Re: no fire
My experience is that a bad oil sending unit will cut spark. The pigtail goes directly to the ignition module. (my books say it wont but I have seen it). The Crank Position Sensor is more likey the cause because they are often temperature sensitive. Good Luck.
