 If you can connect with ECMLink, verify that the ECU is trying to pulse the injectors while cranking (view InjOn). ​ If throttle position (ThrotPos) is too high while cranking, you may be invoking the cranking fuel cut feature in ECMLink intended to help users clear out a flooded engine. If you can connect with ECMLink, verify that the ECU is trying to pulse the injectors while cranking (view InjOn). ​ If throttle position (ThrotPos) is too high while cranking, you may be invoking the cranking fuel cut feature in ECMLink intended to help users clear out a flooded engine.
  
-It's also possible to plug the injector resistor pack into the ISC's connector. ​ They are both identical 6-pin connectors and are located close enough to each other in the engine compartment to be confusing. ​ If you do swap these, the injector resistor pack will get very hot with the key on and, of course, the engine will certainly not start. ​ You can see a picture of this wired incorrectly below. ​ Note the black wire with yellow stripe on the connector plugged into the ISC.  If you refer to the 1G MFI schematic, you'll see that there is no black wire with yellow stripe on the ISC connector. ​ But there is one on the injector resistor pack connector.+It's also possible to plug the injector resistor pack into the ISC's connector. ​ They are both identical 6-pin connectors and are located close enough to each other in the engine compartment to be confusing. ​ If you do swap these, the injector resistor pack will get very hot with the key on and, of course, the engine will certainly not start.  Doing so will also possibly damage the ISC drivers in the ECU.  You can see a picture of this wired incorrectly below. ​ Note the black wire with yellow stripe on the connector plugged into the ISC.  If you refer to the 1G MFI schematic, you'll see that there is no black wire with yellow stripe on the ISC connector. ​ But there is one on the injector resistor pack connector.
