Made a low psi pressure tester to test the MAP, its working. Turns the meth on at like 2 psi and increased flow as PSI raises. All fittings and filter are clean. I have no idea what caused the issue. One thing I havent changed is the wideband o2 sensor. its been through an engine blow up and I'm not sure if it is reading lean when the car isnt. And if thats possible it would only be happening at WOT and not during cruise or idle. ehhh im leaning toward the o2 sensor being fine.
I havent driven the car since rebuild, and its supposed to rain most of the week. Someday I'll get back on this thing.
Alky Control posted a new Meth pump where it uses a pressure switch in the filter. Its supposed to be mounted near the pump and direct swap for older units. My filter is right before the nozzles which is like 12 feet aay from the pump. I also dont believe I have a pressure switch in my current setup. I think its built into the head of the pump. Maybe I should put the filter right after the pump, how Julio is describing it.

"Brand New for August 2021. Pump and Switch. Plug-n-Play with our existing system. The new design moves the adjustable pressure switch post filter, so it will read true pressure from the liquid the nozzle is seeing. There is 30 inches worth of wiring between the pump and its pressure switch. If the filter in the system is located further than 30 inches, please contact us for extensions or adapters. Warranty will now be 18 months on the new pump. Below is the option for the short hose and inline coupler to allow moving the existing filter close to the pump."
