I did the dpfi to mpfi conversion step by step. I'm using a obd0 to obd1 conversion harness, and the following items, a 95 obd1 dx dizzy, with a p05 ecu "95 dx". i do not have the o2 sensor at the moment plugged into the harness. Which i really don't care about. My issues are that I know i'm getting fuel, but no spark. I switched wires c1 and c2, still nothing. Any ideas...

and only throwing a code 1 and 14 o2 sensor not found.
has nothing to do with spark.

 

b u m p. a little help

 

you should of done the dpfi to mpfi before you did the conversion harness.... but i'd check to see if your connections are good.

 

it would be pointless to buy an extra ecu and dizzy, then to go out and upgrade everything to obd1.


i've been trying to figure out why it's not getting spark. i've traced all the wires in the main engine bay harness for breaks all connections are good. i switched the two white wires around and still nothing.

i am not getting any codes that deal with the system be faulty besides the o2 sensor code.

please help anyone any ideas.

 

the distributor youre using is known to be good?

Did the rotor fall off while it was between cars?

 

the dizzy was 100% good when it came off of my other car

 

try puttin the four white wires 2gether... might get it started, but may only rev to 3k rpms, dont know why... i had a shop do my wiring after that

 

wtf?

 

I had the same problem....

Went through all my wiring a million times...changed the white wires a million more...

Took the dizzy apart and changed the coil out with a known working one...hooked everything back up...nothing...changed the white wires...nothing.

Took the dizzy back apart and swapped the igniter with a known working one....put it back together...nothing...

Swapped the white wire AGAIN and FINALLY she fired right up.

It can be frustrating for sure. I knew all the wiring I did was 100% correct.

You'll get it sooner or later man....good luck.

 

anyone know which points the twwo white wires goto the ecu harness? whats the pin outs?

 

are you sure you firing order is correct?? just had to ask.

 

no spark at all.

 

oops brain fart. Well if you have a friend with msd hook that up. I mean it's worth a shot... I know when I disconnected fuses to compression check I was still sparking with no ecu fuse.. (with msd hooked up)

OR!!

I have another brain fart!

1)Buy obd0 to obd1 distributor adaptor.
2)Put the orginal distributor clip on the engine harness (in other words find a obd0 mpfi dizzy clip for engine harness)
3)Find a friend who has a a6 dizzy or mpfi dizzy obd0.
4)Color match it so everything goes in the right order, so... the only pins you really have to worry about is the white ones.
5)If you bought the dizzy adaptor hook it up and clip it in.

the only thing you have to really worry about is those 2 white pins.. That is if you get what I am saying...

Better yet take a picture of how you set your dizzy up and wire job... (-.-) I've done this plenty of times to know what went wrong for spark.

edit : Dont use the a6 dizzy i'm just saying this so you can use it for a wiring reference to put the obd0 dizzy clip on.

 

the dizzy should be hooked up with no issues all but two wires match. the two wires that are don't match are the two whites. I'm going to get my roommate to help me test distributors on his ride.

 

You never said what the motor was... you just said 95 dx dizzy, and 95 dx ecu... so, i'm presuming full 1.5 swap but trans?

What did you use for dizzy clip? Since obd0 and obd1 do not interchange... for clipping. So which one did you use and are you sure you maked everyone of those wires right...

 

I am using the bone stock 1.5 d15 that came in the car, which is an 89 Sedan. I don't know the exact stamp on the block. Which, nobody really cares. The wiring has been converted from dpfi, to mpfi. Then instead of using obd0 parts such as the intake, and ecu. I am using all obd1 items, so obd1 ecu, obd1 intake manifold, and jumper harness from obd0 to obd1. The only thing that is not hooked up from the obd0 to obd1 conversion harness is the o2. This is why my ride is throwing out the code 1 and 6. These are both indications of an o2 sensor not being present. I am not throwing any other codes.

i will take some snap shots when i get to my garage after work.

 

pictures request

 

sorry dude i'm not allowed to IM yet! But in any case, I would check the wiring at c1 and c2 again... One wire is thicker than the other on the obd0 harness. From what I've been told, the crank angle sensor is inside the dizzy but i can't find it. So in your case i would just trial and error. Not the best idea ever but it worked for me... Ummm As for me... I'm getting ecu code 4 and code 10... I could use some help as well...

 

Can you tell me what pin out you can those 2 wires from?? Shouldn't be any hanging or give me color. Orange/??, Green/??

Also can you take a closer pictures of your wiring job? Since I think I see something wrong.. (Basically connection and where you repinned..

(If you lived in Illinois, I could of helped you out in person.) (-.-)

Code 10 is Intake Air temperature, code 4 is crank angel sensor. Recheck your wiring also.

Edit: code 4 try replacing your dizzy it should get rid of it. For code 4 are you sure you have the right plug on the IAT?

 

"Best Method To Do This:
-Pins B10 and B12 are empty meaning there are no wires going into them as a general rule, however some models have a wire at B12 (if you have one that is one there that is one less wire you will need to move).


-Pins B2 and B11 have wires going into them but they are not used for anything (weird, but trust me on this one).

-Take the pin/wire from B2, depin it (this means pop it out of the plug) and pin it (pop it into plug) into B10's empty spot, how you have a wire at B10.

-Take the pin/wire from B11, depin it and clip it into the B12 spot, now you have a wire at B12.

Oh I know that one already. But there might be a fault... Since i've done that dpfi to mpfi and obd1 conversion. I'm just trying to figure out yours.

It shouldn't be this hard... But how did YOU test for spark?

 

friend cranked over car while i grounded out a spark plug. no spark.

tested coil looks fine, i will be checking the icm in the morning before work.

 

sounds good. hmmm this is mind bottling, i'll keep keep this one saved, so I can still help you out. I never saw what you did for the dizzy clips. Can you post a picture?

 

of course i can. pictures will be up tonight. i hope.
