KA24E to KA24DE swap, Won't Start problem!

[jyv]

Hey everyone, I've been reading tons of forums from this site to help me swap out my 89 E to an 91 DE. My "E" motor blow out on me so I asked one of my cousin if he had his old "DE" motor that was still under 70K miles.

My Car:1989 Nissan 240sx Fastback, KA24E, 5 spd manual



The old KA24E

The NEW KA24DE

What the engine came with?

The "TIMING CHAIN" broke so i purchased a new set of timing chains.

All of the wiring from ECU to the engine was uncut besides the harness that runs from the ECU to another plug-in and some wires from the front, left corner near the battery, was cut. I REPLACED them with my old "E" harness, (i wonder if that makes a difference or not) and there seems to be some wires that were left out. And im not sure where to wire them as well.

I also had to put in 1 fuel injector that was taken out and it was the last one, from the front to the back engine, #4. So that was taken cared of.

What did I Install/Purchased/Removed

Spark Plugs – Purchased some New NGK for the motor at autozone

Spark Plug Wires – bought all 4 sets with the coil wires

Distributor – I knew that I needed a new one so I went out and got one. I did set the timing at the "TDC" from a forum on this site.

Timing Chain – Purchased a new set of chains but only had to replace the front chain only. I also timed the CAMS at the Mark where they are suppose to be at from a forum that i read. Intake cam - 12...and....Exhuast cam - 1.

Timing Belts – Got all three of them brand new from pepboys but I only used two because I removed the AC.

I removed the "EGR" system and the "AIV" (i think thats what its called) system and the rest of the air tubes that are removable. I did however, remove the AC (i dont think thats going to make any difference)

The MAF sensor, I used the KA24E and cutted the harness and putted it onto the DE wires. When I got the motor, he had already gaved away the MAF sensor. (im not sure if that will have any effects)

Problem!!!

Now my problem is this, When i start up my car, It cranks and seems like it chokes. Making it seems like its coughing from the INTAKE. I could hear it from the filter as well, making a coughing noise. And sometimes, I can smell a scent of gas within the car (interior). Im not sure if its not getting enough spark or fuel or air. But i do know that the engine does choke up as it is trying to start, but no success.

Link for my video of starting my carhttp://www.youtube.com/watch?v=vMHQe_KTr7U

Sorry for the other car noise, i had to jump start my car because it has been sitting for half a year now.

I will try to post up some pictures soon. THANKS!

[neverlift]

well I'd like to say check your spark.....check the cam timing again,if its choking.

my swap luckily fired right up. lol once I put the coil wire on

[jyv]

LOL thats Good to hear! Too bad mine didnt start up like that, although i was hoping for that first start up as well. But thanks! I will re-check the spark plugs out again and maybe the Timing Chain as well.

[Florida240sx]

My guess is timing. Rotor is probably off one tooth. Or could be off 180. Was valve cover off when you set the dizzy?

[jyv]

Yeah, when I got the motor, the valve cover was off already but than my cousin just put it back on with some screw in it just to hold up. How would i correct the timing if it is 180? I've read on the forums, but still wasn't sure on exactly how to do it since most of them didnt really answer it, according to my search. thanks!

[jyv]

Anyone out there who can help me out or hints etc?? Still working on my motor and no success yet

[jyv]

BUMP

[LayNLow240]

check your distributor timing, and make sure its set at 20*(actually it might be 15*)btdc(next to last mark on the right on the crank pully) and that your #1 cam lobes are pointing directly away from each other like <---> that.

[dkdeleon68]

did you connect the hose (in the pic) that i circled to the intake line that i also circled? if not ,thats where the choking is coming from.

[jyv]

Thanks! but no, i have not connected that Tube that you have circled. I was thinking about it awhile now, but now that you have mentioned it, I certainly will tomorrow. Thanks again, I will try what you have said and see what results i will get, and also update. Thanks!

[sideways aggression]

hey , i am going to run into the same problem i believe. mine was from a s14 also. did you have to replace the rotor dist for a s13 DOHC rotor?

[Soravia]

The pipe in Circle is MANDATORY for fuel to go into your engine. It needs to be hooked to Fuel Pressure Regulator.

Sometimes your TDC is actually for Exhaust Stroke instead of Compression Stroke. So If the TDC you set is not working, rotate it for another TDC, that will fix the 180' off issue.

If you're missing EGR emission parts and plan to remove it be sure to read the diagram I posted. It's easier to remove before the engine is complete, since you need to remove the intake manifold.

[jyv]

Ok, I think i Rotated the Distributor right, this time because now, my engine starts up but than dies. Other than before, it never usually do this. I also have a video clip included.

Situation:First start in the video, it is WITHOUT applying any gas on the peddle. The second start is WITH applying gas to the peddle and thats when the engine finally fires up. The set-up timing is at "15" from TDC. When i let go the Gas peddle, the engine will choke up and dies off, like the end of the video clip.

Just wanted to update as well...I did Remove the EGR system as well and Plug-up them Vaccum Hose that were for the EGR and AIV system. I will take photo's of them as well tomorrow. I've been reading and many people said similar things that it can be a vaccum leak, but I'm still now sure.

I am also wondering if it could be the Gas peddle line to the Throttle. I am currently using my "SOHC" line and it seemed a little to short for the motor, but it managed to reached over.

[Soravia]

So long as it's not pulling the throttle it's fine.Yours should be 20 isn't it? That's the stock setting. Fix that first.

Check to make sure valve cover hose is going back to intake.

[Florida240sx]

stock timing is 20 degress. While it's running and tps disconnected rotate the dizzy. You can be off 1 tooth and still have the car running, just not driveable. So rotate one way an then the other to see if it runs better... But timing light will also show if you are off.

[jyv]

Thanks Soravia! I will definitly reset the Timing at 20 and see if it will fully start. And thanks for letting me know that the Cable wire should be ok. It's not pulling the Throttle at all, so it should be ok.

Here are some photo's that I had taken.

1.) Resetting my Cams

2.) Positioning the Cams. Intake at 12...Exhuast at 1. (I hope i did this right)

3.) Should the Timing chain be this loose?

4.) Over-View look of eveything. (The timing was set at TDC, I haven't changed it to 15 when this photo was taken)

5.) That hose that dkdeleon68 said that needed to be connected, Did that as well.

[stuckeypcs]

If I've read correctly on the board, shouldn't there be 8 links between the inidicator on the cam gears? If that's the case it looks like your 1 link off, I counted 7 from dot to dot.

[bone_stock_240]

Yeah, it seems you are off a link. Your cams should be facing directly opposite from eachother, as in 180 degrees.

[jyv]

Thanks for letting me know about the cam links. I was confused at first, so i had to search it up a bit. But from comparing the two images above, it seems that i should move the Exhuast cam- 1 tooth over.

[FUNGC]

a few things you might wanna look over. your ignition coil. i can see that its from a KAE. irc you need the KADE one.

also your mafs. you need the KADE one. which irc is a G60? correct me if im wrong.

[jyv]

What is the IRC? I was etching about the MAF sensor...but I guess that will be a major problem is i am using the SOHC sensor instead of the DOHC.

[TX-S13]

Man I hate to dig up a old thread for my first post but I am having the same issue, tested the coil, gets 12v, tested the distributor, get voltage, but it does not output spark to the plugs or the wires. I set timing to what the FSM had and I got nothing. but this is the first closest thing I have seen that is like my issue and sounds like it too (thanks for the youtubes. I also could not see the pics of your settings as far as your cams. I need to probably try mine. I will be posting a new thread for my issue shortly. But I would think even if you had the cams off (or at least to TDC notch on main pulley and the Cams set to what the FSM states) it would still at least show some spark on the distributor, am I wrong? I am getting no spark at all.

[240sxprojectman]

alright iam new, and i have a problem and iam looking to see if sumone can help me. i did a ka24e swap to ka24de on a 1990 240sx hatch, everything is connected and hooked up, the right way, i have spark and fuel. but everytime i try to crank the car, it sounds like if the battery is not charged, but its a new battery. and i checked the fuses every single one and everytime only one fuse blows which is 10A engine cont! dont know what else to do........... can anyone help me please???????
