Hello all!
I am having a issue with my SPI mini that I can not wrap my head around. When the accelerator is pressed the engine revs to about 2500 rpm and shuts off the fuel supply. When I look at the fuel injector i can visibly see the injector shut of and stop spraying fuel. When the rpms drop it runs great and idles fine. It may be important to note when I press the gas the car does back fire out of the carb as the fuel shuts off.
I am trying to figure out what sensor would cause the ECU to turn off the fuel?
What I have tried - I bypassed the roll over switch
I replaced the fuel pump
I checked the Vacuum lines
Can anyone offer any advise on what to check next??
Thanks in advance!
