I came across the TI DRV110 yesterday, looks like its just for general solenoids but I'm not seeing a reason it wouldn't work for an injector solenoid when configured properly. I like that the peak-hold ratio is configurable with that ASIC so I can make adjustments and it's a MOSFET driver rather than NPN. An LM1949 is already on the way so I'll try that and go from there.

The pump sensor circuit is doing the same thing as before, thought I fixed the problem with the changes I made but I must've missed something. Gotta take a better look at things, maybe see if I can change the zero crossing threshold to match the sensor output. I've got a feeling its related to the capacitive coupling.
