hey folks
I have a 91 GXL n/a
after a series of event my 7 is dead yet again... but im getting the engine code 20.. which is the oil metering pump sensor... im beginning to think that the pump is dead... but i haven't test it yet LOL my voltage meter died on me. whats the easiest way to test if it works or not...? I do know a omp is $1.5k at mazdatrix. whats the alternate if the pump is dead ? Would removing the omp hurt my emissions?

Buy a used omp or get an Rtek 2.0 & block-off / premix. You can't just unplug it and expect the ECU to stop putting it into limp mode.

would this explain why the car won't turn on in the first place since its throwing the code ? thanks for the advice on the rtek... im looking into it..

I don't think limp mode should keep it from starting. From what I know, it will just severely limit power.

Charge your battery but i wouldn't drive the car....

Especially if it's an omp issue. That IS what lubricates your rotor seals......

Premix.
