I can't get my car to start and the codes I pulled up were P0135(Heated Oxygen Sensor (HO2S) heater circuit Bank 1 Sensor 1) P0530(A/C refrigerant pressure sensor circuit) and P1667(Reverse inhibit solenoid control circuit). The P1667 may be an old code I never deleted.

Anyhow I thought that a Nonworking oxygen sensor would just cause it to stay in Open Loop, which the car should still start correct? I have no idea how the A/C refrigerant pressure sensor circuit would have anything to do with the car not starting. What do you guys think?

 

I would have to agree, with those codes it should start, start with the basics, is it getting gas? is it getting spark?

 

I'm pretty sure it is not getting spark, cause at first it would start for about 1 to 2 seconds. Now it won't start at all. Also I can hear the fuel pump starting. But if it is not getting spark shouldn't I get some sort of ignition code or could the code just not have popped up yet.

 

If the ignition problem is on the high voltage side, between the coil and the plugs, there are no codes that would be set, other than a misfire code if it was running. There are codes for the IC Module, and for the optical section of the Opti, but that's all.

 

The only thing that would be between the coil and the spark plugs would be the distributor, correct? or is there something else I'm missing. By the way my optispark is a new gm one with maybe 2000 miles on it.

 

Coil, coil wire, Opti cap/rotor, plug wires, plugs. All of those parts are on the high voltage side and do not set a code (unless they cause a misfire).

 

thanks a bunch man!!
