I have a new 1911 with L-jet. It was formerly a 1.8L stock engine that ran good. Trying to do the break in cycle but have no fuel.
I have spark and air, but injectors won't fire. I can however jump the relay and get the fuel pump to run. I can also move the flap manually at the AFM and that will also trigger the pump to run with all the stock wiring in place. I tried all the tests at the manuals.type4.org website. It passes all the tests. Only one test is questionable though. ** Measure the resistance between ECU plug terminal 20 and system ground at terminal 17. The reading should be 52-78 Ohms. Mine reads 5.9 Ohms. That would suggest the dual relay is bad, so I install a brand new relay and that one reads 6.9 Ohms. WTH? What am I missing? |
