Chances are that your pcm still is bad if the involved components and the wiring proof good.

I leaning towards ecm still bad as well , this is what I'm getting from the wire corrosponding with the ground side of the injector from ecm. Yes I cut the wire, so that is the gray-yellow wire from ecm pin 28 on the schematics , this ecm is vin coded , so I can't just swap ecm in this case. And I am getting running voltage on the other side of injector plug. Just double checked. Other injector and coils as. Quick Compression test 150 psi, didn't do leak down test though. well.juergen.scholl wrote: With the P0305 cleared the ecm should pulse - at least initially for a couple of seconds - the injector. You may want to disconnect an injector/coil on another cyinder in order to verify the pcm's strategy in this case...

I'm home it's Sunday, i ran out side just now and did a quick double check, on other coils and wires , can check with my scanner at the shop this week.bruce.oliver wrote: Volt meter isn't a very good choice to check an injector circuit. It is not any where near fast enough.

For v8juergen.scholl wrote: A quick glance at the schematic invites to check the other wire from injector terminal 2 to pcm terminal 21 as well.....
