sorry on my typing guys, i was replying to another user and did it wrong. i new and i dont know what to do! sorry. my problems is i just put a 1990 ls into my 90 si hatch. the car had an ls prior to this one and it ran fine. now my car cranks but wont fire. i have spark. fuel pump kicks on, but only getting fuel to the top of the injectors(no smell on spark plugs...) tried 2 ecus 2 resistor boxes, and im stumped can you help me?

 

injectors could be bad. was the motor running before you bought it? same ish happened to a b16 I got! FYI: people love to **** me.
