Part 2 no spark Nissan sentra

I was testing wiring signal from pcm to ignition coils. In Part 1 .getting weird reading from (0.4) to (4.3) volts but after swapping pcm was getting a reading of ... (1.0) on all coils .
This pcm is from wrecking yard also notice was pulled out from an automatic 2002 sentra .my car is manual transmission. .but it worked

Before you tare it apart check out the main fuse and clean up the ignition

Just got my used ecm today for an altima I'm working on. Hoping this will do the same for it. Bueno !

How you checked signal? For voltage? I disconnected the harness from the coil and checked to see voltage and ground and I have good, but haven't the signal. You back probe it also for voltage or resistance? I have a crank no start issue.

green/white wire with key on .not running should give you 12v .if not check fuses cause that green/white wire feeds all coils

Did you have to reprogram your pcm or just unplug and plug back the used one?

[@c14back2nitrogen9]

Plug and play .not the right one but.compatible
