I just dropped a S13 SR into my 95 S14 and its cranking but not firing. when i pulled the #1 spark plug it was bone dry, the fuel system is getting pressure. I assumed the car would at least run on a stock fuel pump. Also as far as my wiring goes, a local shop McKinney motor sports did it but there is no plug for the tranny sensors to plug into my engine harness. I haven't talked to them yet but i assume i need those signals for stuff like speed sensor, reverse lights and ect. any ideas on why the motor is not getting fuel? I think the injectors are not opening. There is also a "Field" map selector controler comming out of the ECU. because the ecu has been reflashed or chipped, could this be causing a problem? The Red LED is on the ECU but i think thats normal.
