Truck turns over for a few seconds before engine turns on

The website you linked was super helpful, thank you!

 

Awesomeness

many progress or plans???

 

Oh just saw your codes

my guess
Is charcoal vapor canister
The 440/441/446

It’s a black box near fuel tank
Now the P0420…..
Has one ‘cause’ that relates to the other 3….gas leaks

a Q laymen’s test…..
Find box
Loosen box
Shake box

if you feel liquid in box, Thats fuel
Replace box, inspect all hoses and filler neck

Haven’t gotten a chance to take a crack at it yet. My guess was either VSV or charcoal canister. The charcoal canister test is way less complicated than for the VSV so I’ll give that a shot when I have some time. I appreciate the input.

 

A firm

keep everyone posted!

 

I've got the same issue. Watching this thread. Keep us updated.

 

I’m thinking it might be the fuel filter or pump. I notice when idling the RPMs drop eeeeever so slightly every few seconds or so. You seeing the same?

 

I haven't noticed a drop in rpms during idle yet but I'll keep a closer eye on it. I have noticed a few times that while in drive at a stop light, the idle will have a single surge. It's enough to have to push a little harder on the brakes because it pushes the truck forward just a bit. Not sure if that is related but it might be.

I've been looking at injectors. From my searches, it looks to be a common cause. But I'm hoping it's not the issue because I don't wanna pay to have them installed and I can't have my truck down long enough for me to do them.

 

Matches…..
Injector install is not that hard/involved on 4cyl(2rz/3rz)
The hardest/most frustrating part is unplugging the 2 pigtails under intake manifold
Take off tube after air box
Take off steel reasonator(over valve cover)
Then unplug the engine wiring harness from front to back….4 blue injector pigtails/2 throttle body PT’s/1 10mm ground and bracket/2 pigtails under manifold and unclip diagnose port
Move the unplugged harness to the firewall
2 bolts hood fuel rail
1 bolt holds fuel line(need 2 copper crush washers)
That’s it
U don’t have to remove TB

on my 2nd time to do job(shitty eBay injectors) literally took me 45mins

search for my thread with pics

 

That does sound easy. I'll reference this post if I ever get a 4 cylinder taco.
