No Start after Coolant Flush/New Rad

Hey All
Finally Got The rad installed after 8 flushes

on the 6th flush, very hard time starting
ECT sensor popped, I cleared
(Was thinking bc no coolant in truck during flush process)
Code has not returned

this morning
It’s a problem….wont start

I can get started after a while if cranking. But if you tap gas pedal BARELY….she dies

no current codes
Fuel pressure gauge reads 46lbs
IMO this issue is not from flush/rad install
Thanks for input

 

ControlCar, remind me what kind of injectors you are running? You replaced them right? Sounds annoying, probably something simple. Double checked and made sure everything was plugged back in/reconnected? Will be following.

 

You said you had a coolant temp sensor code.

What is your coolant temp reading? With the engine cold it should be reading whatever ambient temp is +/-5 degrees.

 

motorwest RM’d injectors(my old OE)
Not one hiccup since installing 3-4months ago

 

last time I went to a shop of mine, their Snap-On computer would not connect with the taco
OBD port does pull/clear codes thou

 

Any tests I can do for MAF sensor/distributor?

I have acquired both(thanks speedy tech)

 

Can I test the 1month old ECT sensor?
(Continuity)

 

Unplugged the ECT pigtail
Kinda started (with finagling)
Popped P0115 again

 

Got her running again
ANY movement of gas pedal or throttle cable make engine shut down

she’s running now
Air bubble?
I dunno

get her up to temperature and see if I need to add coolant

 

Taco warmed up
Throttle responsive

throughout the 3 day flush process
The taco had just idled in driveway

taking for a drive
Maybe will get “juices flowing “
I.e coolant

report back

 

Came out to the idling truck b4 the drive
And codes popping
Same P0115 & P0145 (front O2 that I just RR’d). ????

cleared both
Then 15m hard drive
No issues on the drive

letting cool down
Make/eat dinner with kids

Then will
-check coolant level
-see if starts like normal

 

Dang it. Hope you get it sorted out.

 

ugh
Part of wrenching/owning old vehicles
Made my bed.

 

Reckon that p0145 is from where you checked rail pressure? That ECT p0115 gunked up from the flush moving stuff?

 

I got fuel pressure gauge
Shit man….maybe

I also bought(for home project) a current detector….to see if current in outlets and wires. took that tool to the distributor, tool beeped everywhere near dizzy


I’m hoping bubble

And
That coolant funnel kit I told you about…..didn’t fit. I’m trying to bleed old school way. I must say, I have only added 1/2 cup of coolant after filling rad/running up to op temperature
On inclined driveway when done

I’m totally on the fence if this is just a symptom of this major flush I did or something unrelated thst just started occurring

 

That harbor freight kit worked great. You burping things, squeezing hose? I had to add a good bit after getting up to op temp. Don’t recall exact but it was more than a half cup. Thinking more like quart or two.

 

^^^right!

Amazon
Even after bending correct cap tabs, would not seal with funnel

yeah squeezed both hoses
I’m really hoping air bubble

 

Ugh
No start this morning
No codes tossed either
Basically no coolant(2oz’s?) would add to radiator

 

Update (nothing good)

my CA friend that has 22R and built my RSTi had some time today
Went through some testing

unplugged MAF and she started much more easily…tossed MAF code
And if I touched throttle, truck dies

now that I can actually start the truck
-modified coolant bleed funnel even more
Attached the same
Jacked up front of the taco as well
Heat on….30mins idle
Funnel added another small amt of coolant
But
Saw coolant res was way below lvl last I saw it……maybe 16oz I added
Wrapped it up, shut down/put away Jack and tools

Truck still warm
Still de de de de de de
No start

 

CA friend advs me of this threat
