If there are any problems, they will show up on our board, and not later on your car. I ve just installed my fuel injection system and the engine turns over but it won t start. This wire must be hot in the start and in the run position or the car may never start. We suggest using the coil feed circuit. Put the fuel filter on the pressure side of the fuel pump.
Fuel is what lubricates and cools the pump.
When the filter plugs up, the the pump is starved for fuel. If the filter is put in front of the pump, the pump has to not only push the fuel to the injectors, it has to pull the fuel through the filter. TBI systems require 15 psi and TPI systems require 45 psi. Too much fuel pressure is not a good thing as the pressure regulators can only handle so much pressure. You also need to change to a MAP-style knock sensor.
