Default Injectors wont fire on SR

Hey guys, i need some help. The swap is done but the injectors wont fire. It has fuel pressure and spark but the injectors wont fire. I am thinking that this could be wiring, ecu, or maybe cam angle sensor not sending signal? I would appreciate some help....

All opinions are welcome.....



Thanx
Norlandt

are you spark plugs wet with fuel? if not check for continuity in your fuses and if that doesnt work pull out the injectors and spray it down with carb cleaner. may be clogged. if that doesnt work try and get your hands on a noid light test to see if you injectors are even getting a signal

The cam angle sensor is working... we have spark.. so that verifies that. The injectors aren't firing at all. I have a test light for the MSD injectors, and there's nothing there. I have verified the 12 volt feed going to them.. and double checked the grounds and resistors. All of that is in order.

Just for the record, how do you have the injectors wired? What size resistors? Have you back probed to the ECU? This is a stock ECU, right?

I have the resistors on the negative (-) switched side of the circuit coming out of the ECU. I am using 6.8 ohm resistors.

we are using an ecu programmed by enthalpy (scott).

yes they do...but 6.8 ohm 10 w is the proper resistor. same resistance and wattage as in a honda resistor pack!!
