Possibly blown head gasket causing it to pressurize the water jackets.

Did you have the head decked and pressure checked?

Does anyone else have trouble putting their car into reverse on a stock KA24DE motor and trans? As if the gate isn't opening, not allowing you to throw it into reverse.

Yes I used a felpro head gasket and arp head studs

I'd say make sure you bled the system properly before considering your brand new head gasket faulty. I use Lisle Spill-Free Funnel and love it:

Ka24de. temp gauge goes all the way to *cool* it says when I turn on the heater on for a little when I turn it off, it *warms* up and goes back to the middle this happen to anyone else? Im just curious why this might happen. I did a quick search and couldn't find much

Had a similar problem, but mine would drop to 'cool' once I've driven on the freeway for a bit. Turned out to be a deteriorated seal on the thermostat, replaced it and all has been well since.

Car idles, then dies when you give it gas.
Car won't idle with anything but starting fluid.
Replace fuel filter
fuel pump relay tests good
Replace fuel pump
check spark
check injectors
replace fuel pump
fuel pump won't spin up.

It's a ground, isn't it?
Oh, God. It's a ground.

Please help!

Any AZ peeps in here know if Boost Junkyz is still doing business? I noticed they haven't been active here for awhile.

Bad ground? Gauge grounding when switched on heat?

Otherwise you may need to replace thermostat, the heater may be allowing a higher flow than the t-stat is. Rare signs of it failing

Unless you're driving in cold ass weather.

Mine would do that in the rare North Atlantic Florida winters when I used the heater it would suck the combustion warmpth right from the engine.

Id have to turn the heater off on the interstate just to keep normal op temps.

But double check with another gauge just to be sure it's not a cluster temp switch issue. Could be signs of low coolant in the engine or air bubbles since the KA has dual temp sensors.

Any of you guys know much about rom tuning Nissan Ecus? I've found daughter boards online for s13 sr20/kas and s14 sr/ka but was curious about boards for the rbs/vg motors.

Im super in DIY and was thinking about doing some local tunes super cheap, can get a running tune going for half the price anywhere else. About 200 bucks with basic setups, if they want dyno/real time tuning I can use emulators instead of swapping out chips 24/7

Are you getting actual power and ground to the fuel pump? You seemed to check a lot, but didn't mention the basics. Did you pull the fuel feed line off the fuel rail and prime the pump to see if anything was coming out before replacing the pump and possibly making a second or third problem?

I think you would be hard pressed to find people willing to entrust their engines to someone just learning how to tune. There are a lot of values you could mess up, and just leaning out someone's motor once can cost you or them a few grand. Not necessarily worth saving a couple hundred bucks. Especially since you're so geographically close to tuners with decades of experience like Martin.

SR guru's PLEASE read:

S13 SR in S13 vert (prior owner did swap/wiring)

Motor will crank over but not start unless you give a shot of starting fluid OR bump starting the car in gear, It runs flawlessly when running.

I have spark and fuel. Pulled plugs, CAS and fuel rail. I observe spark and injectors pulsing fuel while rotating the CAS. It has been re-timed properly.

It runs and drives great and WOT pulls seem normal.

Orange signal wire has 12v while cranking.

Fuel pump has 12v with key on (not sure about constant 12v while cranking at this current time)

ANY suggestions will help,

Looking at the s14 SR20 ECU pinout, what does 'pin 47 - Check Connector' do?

I'll double check when I get home, but if you briefly short it, the check engine light will flash as the O2 sensor cycles between rich and lean. If you short it, the light will blink error codes.

I don't remember if it was short to 12V or ground though. Just remember I accidentally triggered it and thought my car was broken because the CEL was blinking erratically.

Edit: the Wiring Specialties harness connects the check connector pin to the OBD2 connector. Shorting these two pins puts the ECU in diag mode:

MAF/MAF plug correct? Is 'Limp Mode' part of this equation due to the MAF not reading correctly?

Anybody have any suggestions for where i should get my car tubed in ny area. I have a aem ems and dont wana give it to some bozo that kinda sort of tunes.

[mr.nismo.]

Quick question. I have an s13 sr and want to hook up a charcoal canister to it. I see how it's hooked up per fsm( straight to TB) but my question is how is it regulated ? Is the usdm charcoal canister different from Jdm? On the KA it's regulated by the egr solenoid so I'm unsure how it will behave on the sr. Thanks in advance! Been searching and searching with no real answer

[dorkidori_s13]

why in gods name do you want to use a charcoal canister?! if youre thinking youre gonna pass smog legally with it by fooling the inspection on visual, its not gonna happen! the SR didnt use an EGR setup at all... the AIV inducts air into the 02 housing or downpipe (i cant remember which). oh, so youll also either need an OE downpipe/02 housing or to cut a hold and weld a bung in.

but if you MUST run one, I believe its setup mimics the USDM layout identically... though youre going to need an OE SR AIV and boost solenoid setup which are EXTREMELY hard to come by these days.

SR boost solenoid + mounting plate:

What could cause hesitation at lower rpms on a ka? It only happens under light throttle and goes away after 4000 rpms. It's not that bad of a hesitation and it idles and drives fine just kinda annoying to drive in traffic

[jared420sx]

4,000 rpm on a ka!!!! How!?

Little better description would help. What do you mean by "hesitation"
