Leaving the gym and engine won't crank.
Battery is good, reading 12.4v
all dash lights and electronics are working as normal.
Normal. I tried bypassing the relay after swapping with no joy.
fuses are good.
I'm pretty sure I can hear the fuel pump
I do have a abs ecu ground fault code
I only hear clicking inside and nothing from the engine.
I'm kinda stumped and have no idea what to look for.
also battery terminals are tight with no corrosion.
any ideas would be very helpful

 

Also. Today my engine was having trouble accelerating, and around 2500 rpm. Random misfire codes populated.
I'm leaning towards replacing the crankshaft sensor

 

Does the CKPS prevent cranking?

 

No

So you jumpered the relay and still no clicking from the starter? It should have at least pulled in the solenoid. You can jumper from the bat cable to the trigger terminal on the starter relay with a screwdriver, that should at least trigger the solenoid. If it doesnt you have a bad solenoid. If you it clicks but does not spin I would guess worn out brushes. Starters last about 175-200k depending on # of starts.

 

Update, I jumped from the starter lead to the brown wire for the starter and it started fine. Ive started it with no problems about 4 times now without issues.

 

I do have a bunch of random misfire codes now, and more.
system too lean on both banks.
Cylinder 4 misfire
cylinder 8 misfire
random misfire detected
knock sensor 1 circuit low input bank 1
misfire detected with low fuel level
cylinder 5 misfire.
just replaced plug wires with Silicone NGKs and
replaced all plugs about a week ago
head gaskets were replaced about 2 years ago
Upper and lower intake manifold gaskets about 2 months ago
Starter about 6 months ago.
not sure what the issue could be.
​​​​be.
coil pack?
Faulty ground somewhere?
cps?

 

That many random codes - low battery

 

What about bad ground connections away from the battery?

 

It's been starting normal. After erasing codes, I keep getting a cylinder 4 and 8 misfire. Random misfire detected. And knock sensor low circuit.
coming to do a compression test today and check ground connections

 

Hmmmm, 4 and 8 have almost nothing in common other than the side of engine. I would normally swap plug wires as a start with cylinders than are not throwing code, and then plugs. I like to compare known good with suspected bad. You can swap the knock sensors left and right to see if that is the issue.
