hi, i am needing of some help please. i have a 94 rx that wont start. i installed a single to4s and still have stock ecu. the engine fires and has fuel pressure to the rails. i can spray some gas in the intake and it starts right up. i do have all the smog crap removed as well...can this be causing the no injector pulse problem? i checked the crank angle sensors , they checked good, and also installed a new engine wiring harness. any ideas are greatly appreciated. thanks.

 

double check continuity from ecu to injectors wires

 

double check the ground wire from the injectors also.

thanks. the ecu plug was the problem.

 

So it started? Awesome!
