Okay, I just performed an lb9 swap over my 2.8 v6, everything is installed, but for some reason, the injectors wont pulse to fire. I know the ecm is supposed to ground the injectors out, as 12v is supposed to be constant at pnk/blk wire. Also, when cranking, with my scan tool hooked up, no rpms are registered when it turns over, and it shows a desired idle of 3188?? im not finding any wiring problems, ive pretty much done everything but ecm replacement. Has anyone any advice?

 

so u are using the same ecm for the v6??

 

nope, its the 5.0 tpi ecm,

 

what car did it came from b/c it could be a vats problem, if the computer u installed has vats in it and ur key dsn't match the resistance ur injectors wont have any pulse

 

the harness, ECM and tpi setup came from an 87 camaro, automatic. No vats there

 

is the distributor and module new or u are using the one that came with? check the ignition module, that will also prevent the injectors to pulse.

 

the module and pickup coil are new, i traced the ecm reference wire out of the ICM purp/white, and it goes to ecm, with no shorts or problems , tested ICm and pickup coil with old school vantage meter, tested good
