No Start after Coolant Flush/New Rad

Alright
Sensor arrived
Easy install
Definitely easier to start(only 6 turns of ign cylinder)
Touch throttle, still dies
Threw P0110(air temp sensor again)
But got better much faster than before the new sensor was installed
I.E. could rev engine fully in 20 -/+ seconds instead of waiting for operating temp (8-10 mins)

Guessing ecm learning bc now has good signal from sensor(????)
Cleared code too

b4 the taco warmed up, I shut her down

Will try again when she cools down

 

Update

she starts much easier but not as in the past
Took drive, no problem, no hesitation, good power
Got back in neighborhood, popped P0115
The ECT code again!
Cleared twice, pops immediately after the clear

coolant good (rad level)
Coolant good((reservoir level)

And
I discovered that if engine running, my crappy OBD reader does have limited “realtime” data…….

 

Coolant temperature shows 284?
Intake temp 113?

like DM93/speedytech stated, points to ECT sensor
But she doesn’t start when ECT pigtail unplugged?

im going to try unplugging ECT sensor again….
When she cools down

 

Yeah that coolant temperature sensor is toast. That's a fully maxed out reading it's open circuit

 

That's why I wanted to see live data, unplug the sensor and see if it goes to -40.

If it does we have a sensor problem, if it doesn't then we have a wiring or PCM problem.

 

A firm y’all
Will update tomorrow

unplug sensor without clearing code
Start and get hopefully get live data again
Appreciate You both

 

U Da Man

 

-unplugged ECT pigtail
-tried to start….nothing….V’s are at 12.0
B4 I ran down battery
-plugged in reader…..

 

The old ECT was broke if I remember correctly. Was the new one OEM? Had to ask.

 

Nope!

AAAAHHHHHHHHH


6 months old
Under warranty
Just returned it (Vatozone)
I’m buying the $50 Delphi one (with $23 credit)

I’m a glutton for my AM punishment
Nobody to blame but myself.

let everyone know what happens when installed

 

Despite the 104 heat index today
Installed new ECT that arrived yesterday

vroom vroom vroom!
Started exactly like normal

thanks all for the help/advice

Just for newbie wrenchers…..
1st time I RR’d ECT sensor…easy 1.5hrs
3rd time I RR’d ECT sensor….20mins

cheers everyone

 

Way to go!

 

YO
Just to update
Kid had track (Xcountry)meet over 1hr away
So 2hr + trip 70-75mph
No issues!

 

It's good to hear when stuff actually gets fixed.
Happy for you!
