Truck ran out of fuel at quarter tank, no lights prior to, and when I got some fuel in it and started, I had a cel shortly after for p0341, and p0230, and the tach doesn’t work, rest of cluster works, and tach works on the tuner screen, also seems to make a weird noise under the hood kind of in the front cover area, Sounds like some kind of knock or something

It’s just so weird to me that on my edge cts2 monitor it monitors engine speed and while I have a dead tach on the ic, the one on my monitor reads just fine

Exact same thing on my donor ecm, I bet it's in ecm or wiring/pins. Be nice if you had another one to try

Just got ecm back from repair and while they said the lift pump circuit was bad and repaired, everything else in the ecm was good

The vp44 also computes RPM from its internal position / speed sensor and sends it to the ECM by the CAN bus. The edge gets its RPM from the bus.
