My LS VTEC takes like 1-2 mins to start up. I turn it off, it runs for a second and dies. It turns on for a lil longer after some gas starts flowing, but I press gas and it chokes immediately during cold start up. After A couple times of choking it finally turns on n stays on. If I press gas all the way right after, it clogs up and almost chokes. What do you guys think it is?

When I built the engine it didn't do this, until after 200-400 miles.
It used to start up from the first try and ran perfect.
The cluster never worked and after 400 miles I changed it and temperature gauge was overheating like crazy before I even drove a mile.

I changed the block with a great working block, got adjustable cam gears, aligned everything and still same problem. I think the throttle still clogs up if I'll open it up all the way while driving.

The build:
B18B1 block. stock.
JDM B16A head. stock.
Blox Intake Manifold.
VMS Adjustable Cam Gears.
DC Headers.
12 lbs ACT flywheel.
ACT clutch.
Short ram Intake.
LS transmission with 1.5 clutch LSD.

I hope this is enough for someone to help me out here.
I'm thinking about playing with the adjustments on the cam gears after I get enough research to do it RIGHT. I can post videos of how it starts as well if requested.

 

Did you build the bottom end how were your bearing and piston clearances

 

How about getting it tuned? It's a crazy tactic that just might work.

 

Tune it or chip it temporary

 

The clearances were great, no problems. Plus that block is outta the picture now.

To tune it or chip it is expensive, I got p2t ecu. Obd2.
You're thinking the air and throttle might be out of line?

 

I guess google made me wanna tune it after all. Do you know what's a good n cheap way to go?
How much would an average tune cost if I'm still running Obd2?
Anybody in Portland OR that knows wwho can tune for good n cheap?

 

Chip it but don't drive it too hard till u get on the dyno

 

Check out phearable.net or xenocron, both can help you get a ecu and a basemap.

 

Its a amazing concept, that till to this day, isn't understood.

 

Then just quit while your somewhat ahead.

 

I'm actually all the way ahead FYI

 

But the weird thing that baffles me is,,, How did it purr and run super clean for the first maybe 200-400 miles?

 

Compression test and leak down test.

Stop asking people for answers and start with the basics

 

That's all good. I heard the motor run before I took it out of integra and swapped a B16 head on the B18b block.

Motor ran great!

 

Have you tested fuel pressure? Following basic diagnostic procedures can typically lead you in the right direction.

You know it has spark since it starts. If everything mechanical is in check, you can take that off the list. Its at least getting some amount of fuel so you know the injectors are working. Plus if you took this complete setup from another car which ran good and then put it in your car which makes it act funny, i would definitely be looking at the fuel pump and testing it.

 

Btw, this isnt exactly a all motor/na topic but ill let it slide this time as its going to likely be an easy fix.

 

I don't have a gauge so I took off the gas line that goes from that lil canister to the fuel rail. I turned on ignition, and fuel comes out for 2 seconds.

FYI: After I finally get the car started, the gas works great.

I heard some1 had a similar problem bcuz of P2t-a11 ecu. They replaced it with a p2t-a12 ecu and the problem got fixed.... O.o

 

We already knew you were getting fuel since it at least starts but the pressure may not be enough. You are not going to get any useful help without real data to narrow things down. Just do like everyone else and throw parts at it.

If your injectors are not opening enough to start the motor, that would be a tuning issue. Do you have the appropriate injectors for said ecu?

 

Oops my bad.

The fuel pump works great. I just adjusted the dizzy, started it up and after a lil playing around with the throttle it was running. Plus it aint that cold, on cold start its more difficult.

I took it for a spin and it drives good if I'm smooth on the gas. When I step on the gas it kind of bogs and gradually picks up speed, instead of immediately taking the power to the wheels.

EDIT: It also has a CEL. I think its P0133 but not sure. Says either 1) Intake Sensor. 2) ECT Sensor. or 3) Faulty wiring. Probly cuz I have short ram intake.

 

Yea it has stock d series from my d16y7 injectors. So no problem with injectors.

I'll allign the adj cam gears exactly cuz its like 2 degrees off and see if that makes any difference.
