Wont start, rpm signal to commander but not tach.
Fd on pfc, single turbo
So i have been trying to get this car to start on a harness that was made by a shop and I'm running into some issues. All grounds (one near ecu, 2 in engine bay, chassis to motor) are good (one was loose next to ecu when first trying to start). The car turns over nice, but it feels like its in a limp mode, engine won't catch or cough or anything. Just smooth turns from the starter. I didn't even get a hiccup when i sprayed some carb cleaner in tb. The tach doesn't get any signal when cranking so a friend suggested the cas, but then i checked the commander and its reading a steady 220 rpms when cranking. tps,cas,inj's,ign coils,O2 are all thats connected right now to see if it even runs on this harness... Any takers?
