The small fuse box attached to the positive battery terminal has three fuses in it. Pull the MPI fuse.
When you compression test, only pull one plug at a time, then make sure you are florring the gas while cranking the engine.
You should hopefully get numbers 160+. #2 will likely be the lowest, but if you have any one cylinder that is ~20 psi off from the rest (greater or lesser), that is beyond service limit. Minimum you should have in any one cylinder is something like 125 psi (I think that is service limit) but you want much higher than that.
