i have a 89 ef2 civic sedan which had a d15b2 i had to swap out for sumtin a lil better went to the sohc zc motor.. i had to do tha dpfi to mpfi but having problems from the beginning...lol fellow ht members have helped me so much but done with the mpfi swap and the car wont start...

has compression...gets spark... gets gas.... main relay clicks... fuel pump prime... fuses r good... but no start jus cranks

ne response with help are greatly appreciated...

 

Are your sparkplug wires in the right order.... and are your fuel injectors wires in the right order....

 

did you chane the fuel pump or the feul line

 

Wtf kinda suggestion is that lmao. How's that got anything to do with his problem. Wat a noober

 

Says the girl that joined the same month as he did... Srsly rofl... op did you do the dori to mpfi wiring and if so are you certain of what you did?

 

I may be new to this site but I'm not a noob to working on hondas I've been working on them for almost 3 years. Yes I may have joined this month but I kno how to trubble shoot problems and to work on my own car. Never once have I asked for help yet but if I ever do need advice I kno there are people on hear with great knowledge of these cars that will help me or any one else that needs help on hear. So call me a noob idc you where once one to!!! I joined to help others who may have problems and don't kno how to fix them or need advice on wat to do to try to figure out what's rong with there car. And also to help me expand my knowledge On hondas. Yea that's a mouth full I kno. But just thought you would like to kno

 

And clipsed if u would have read. He has spark and fuel so the wirering must be right. But is it getting the fuel and spark at the right time on each cylinder. Hummm. I think I'm on to something hear.... but he could always go back and make sure the wires are right lol

 

Just because he has spark and fuel doesn't mean he wired it correctly.

 

My swap didn't fire up for the longest time because it took a long time to prime the system. After I got the car running the check valve or whatever it is that keeps pressure at the rail for the next startup wasn't functioning properly so the car would crank for a while before it would start. I doubt this helps anyone but those are the only problems I ran into with my DPFI to MPFI swap.

 

i had a similar problem....it was a fuse for the main relay, check fuses and grounds, connections at ecu were u did the wiring, could be a loose but connector or tape, assuming you didnt solder....maybe you did maybe you didnt....check it all again and again

 

[QUOTE=Clipsed;44293424]Just because he has spark and fuel doesn't mean he wired it correctly.[/QUO

Wow really is that all u got to say. If he didn't wire his dizzy right there would be no spark at all some one beside clipsed correct me if I'm rong....... and if he wired his injectors rong they would not be Squirting fuel also some one correct me if I'm rong..... for now I rest my case!

 

Goes to show how little you know about hondas and wiring. He could easily have wired the injectors in the wrong order meaning they are still firing but in the wrong order. Seriously man do a little reading you could actually learn something. Now stop filling the ops thread with worthless bullshit. You know what's even funnier is that you had already told the op are his injector plugs in the right order what if they weren't tell me what would happen oh so intelligent one please enlighten me!

 

You must be retarded read my first post. Lol CLEARLY STATED ARE YOUR FUEL INJECTOR WIRES IN THE RIGHT ORDER. So how about you stop trying correct me and go correct your self. And I hope every one sees a noob showed you up dude I kno I kno wat I'm talking about but I'm not sure you do.

 

Lol that's exactly what I said dip **** lol tell me why would you say that what symptoms would it cause don't ignore the question lol. I have a number of people that can vouch for me and my wiring skills and abilities.

 

Let's see hear pin a1 should be running to injector number 1 next to the timing belt the wire should be brown. Pin a3 should be running to injector 2 wire color should be red. Pin a5 should be running to injector 3 and the wire color should be blue. Pin a7 should be running to injector 4 witch is next to the dizzy wire color should be yellow.. and now for the other wire on the fuel injector plug they can eaither be red/black for obd0 injectors or yellow/black for obd1 injectors they are the positve leads for the injectors if you use obdo injectors you must run the red/black wire to a resistor box and then run power to the resistor box from pin a13 or pin a15 if you run obd1 injectors you just run the positive wires yellow/black to pin a13 or a15 no need for resiter box cuz they are not low impedance injectors like the ob0 injectors. Now for your question. If the injectors wires where not in the right order. The car will not start do to the fact that it will not be firing Fuel in to the right cylinder at the right time. For your motor to run you need three things fuel spark and compression. At the right time. On each cylinder. So there for if the injector wires are in the rong order he will not have fuel durring compresion there for no power = car will not start. Good enough for you

 

Stop giving out incorrect info, and please go back to school to learn proper English, grammar, and sentence structure. Pins A13 and A15 are run parallel and not only hook up to your injector resistor box, but also run to your main fuel injection relay. Also your answer is not completely correct. Fuel at improper intervals will create no combustion, without combustion in the cylinder, the motor will not run. lawlz at your "power" statement. What is there no horsepowerz!? rofl.

So Mr. knowitall, tell me, if you do a proper dpfi to mpfi conversion on a dx and use a d16a6 from a USDM si, how many plugs are unused? Clue... It's a trick question.

 

Wat was incorrect about my info. That I didn't use combustion my bad. Yes you need combustion. Combustion happens when the fuel and air are ignited by the the spark plug and that happens on the compreson stoke. In not saying I'm a kno it all cuz I will admitt I don't but I have done 23 dpfi to mpfi swaps and they all work. And there should be 3 plugs left over on the stock dx harness. 2 plugs for the dpfi injectors and 1 for the tandem valve.

 

I will also add this to. To complet the swap you must depin wire c1. and c2 and move them to b10 and b12. Move c1 to b10 pin c1 is a orange wire. Then move c2 to b12 pin c2 is whit. Now that those pins have been moved to where they should be. Pin c1 and c2 should be emptey. You now add 2 new pins where you get yours idk but I just go to junk yards to get extra pins. after the pins are installed you extend the wires out to the engine bay. The wires are for the cylinder positioning sensor they are blue/green and blue/yellow they get connected to the mpfi dizzy the dpfi dizzy does not have that sensor. You also have to extend the tps wires and switch the 2 outer wires. Oh forgot this you also must depin or cut the old dpfi dizzy plug off and repin the new mpfi dizzy plug or match the wires. Up if you cut them

 

Like I said it was a trick question there's 2 plugs leftover because a 3rd is used on the d16a6 I wont menion or say where if you're smart enough to read wiring diagrams you can figure it out if not oh well there will still be one stupid person in the honda scene.

 

well to be honest clipsed. I never swaped. A d16a6 in do a dx or any other ef civic or crx all the dpfi to mpfi swap i did where for b series Swaps And yes I kno how to read a wire diagram lol. Let's be men and drop this we both kno wat where talking about. We argued are points. But u called me out yes I'm new but. I'm not some noob asking dum *** question. Or giving bullshit answers. I can hold my own when it comes to cars. Yes I have a lot more I can learn but we all start some where. That's why I joined this site to lean more stuff about hondas and acuras and give help we all have are own opinions and answers and some go other routes to do things. And I looked up wat the other plug is for the fast idle control valve

 

Not the thermo valve, close but no cigar. Anyway I agree, you have a clue, but still aren't 100% there. More than most though I'll give you that. My point was you calling the other dude out the way you did, it was unnecessary. OP will need to sift through all of this now.

 

Good we can agree...let's call it truces no hard feelings over this. And only reason I called the other guy out is Look at what he posted lol. It had nothing to do with the op guestion. Lol.

 

im glad you guyz are done bickering....lol i still need help... finished doin the mpfi car starts but throws a code 16 and 14.... i checked all the wiring but havent khanged the injectors yet... what else could cause the code 16.. and where is the iacv located and wat clip is suppose to be plugged into it??? anybody ASAP

 

no remove that wire from a15. put it where it suspose to go. ..........this is what u do

there are two yellow and black injector wires that go from the 2 dual point injectors, locate those....
Step1
solder the 2 yel/blk wires from the dpfi harness together.
Step 2
from the two wires that are soldered together, solder another wire from those two, to the injector resistor box. here is a pic to help a lil. its for obd1 injectors but run ALL YELOW AND BLACK WIRES TO THE RESISTOR BOX


BAAAAAAM!! ur good


the aicv should be the green plug from ur dpfi harness

 

Soldering those* together isn't necessary.
