0U100 no power to fuses #41 #42#45 on a 07 hhr . No crank
 

Bought this for the engine , my 09 engine was bad. But it turned out that the car only had 141,000 miles on it and it was really clean so I decided to keep it now it won't crank I've read these forms for 2 days and done every single thing that was suggested and still have no power going to #41 #42 and #45 fuses and ran the scan and came back no communication with ECU /TCM .
Tested fuses they all came back neg on one side.

Does everything include gorilla tightening the 4 bolts in the under hood fuse box, checking that there is 2 large wires connected to the front lug and 1 wire on the rear lug of the fuse box and checking all of the fuses on the BCM (inside fuse box)?
What year is the car?

It's 07 , donor car 09. Gorrila tite, all fuses have power except 41 45 . 2 days of grounds fuse box ECT...the fuses are ground not positive . Everything else is fine. Checking PNS next. One other question I have a good donor car with bad motor. Worked perfect . Can swap everything to make the 07 work. Keys ecu ECT ... Without flashing .

We think it's the PNP it's possible it's in wrong position .

That’s plausible

Could you please translate to old man speak? I am assuming 2.4L?
If 41 & 45 have no power 33 should also be dead. They all get energized from relay 26.

26 is hot on 2 legs forced relay to close now 41 and 45 are hot and fuel relay forced on .still no crank

There is a link to FREE shop masnuals in my sig, the wiring diagrams are in it.

Think the new ecu from flashmasters for 109.00 may do it. Hope the TCU and BCU are good . I had every fuse but 41 45 42 no communication with ECU or TCU . Seems you can do this on a home computer with a tool? Is there any that didn't cost 1000's or a cheat? Thank you for all the info 2 days of reading I know a enough to get it done. Tried the 09 same part number and everything came on for a sec.

👍 Thanks
