What do i do to feed these little guys?

What do i do to feed these little guys?

I'm a mechanic and we found them after they narrowly avoided getting hit by one of our trucks. Theres lots of stray cats around and we are in a highly industrial area. We scooped them up and made them a nest with rags and got some water. They appear to be doves

What do i feed them with? I dont have time to get them to a rehab place within the next couple days and I dont want them to die on me

Sluggish CAT C7 Pt 2 - scanner edition

See my previous post for full details but TLDR- Cat c7 ran better when IAP sensor unplugged.

Here some more details after further testing and getting my hands on a snapon scanner:

Tested wiring- 0 resistance on wire going from IAP sensor to ECM. 0 resistance on wire going from ECM to IAP driver

Parts that have been replaced

- diesel fuel pressure sensor

-intake manifold air temp sensor

-IAP sensor

-air filter and fuel filters

This is what is confusing me. After running a Injector actuation pressure test i got this- without overriding anything it runs around 2100psi with a 52.5 % amperage (sluggish and underpowered) at idle with PTO on

When I manually turn the pressure down to 1000psi and a 35% amperage it runs way better.

After testing another truck with the same motor it runs around 2100psi and 35% amperage at idle with pto on and runs great. The only difference im seeing is amperage. My question is, what does that amperage specifically mean, is it output to the IAP driver? And why does lowering the pressure in the HP oil rail make it run better? I'm totally lost

Sluggish CAT C7 ACERT

Hey all, Im dealing with a HEUI Cat C7 in a freighliner street sweeper. Its sluggish as all hell and when the PTO is engaged it basically does not want to move at all.

Runs great and full power with IAP unplugged

Keep in mind i do not have a scanner nor access to one

Here is what i have tested and replaced

HP oil rail pressure is good (3-4K psi) even under load when it does not want to rev up

New HEUI (last mechanic just threw parts at it)

New IAP sensor

IAP sensor is receiving 5v and gives off linear voltage as engine revs up

Good fuel pressure (60psi)

New fuel filters and cleaned air filter- verified boost

Tried the unplugging the IAP sensor trick to close loop the ecm and rule out a bad IAP or bad readings from other valves sensors and it got its balls back.

Im leaning towards failing ECM or bad wiring since everything else checks out. Any ideas or is it time to start looking for shorts after the sensor (please for the love of god not more wiring)
