ok i ran into a problem with my b1 to A6 swap.

everything is set motor cranks but wont fire theres a relay that freaks when it is cranked.

this swap my friend is doing most of work being i suck at life *well i helped and learned a ton*

here are some pics that i hope help





PS guys i start college back up really soon so i need this running ASAP TIA

Edit: i am using a custom made harness the link is http://norcalcrx.org/nikita/ha...2.htm

i know its for a b16 but long story why i dont have one *for now*but being it also had the MPFI stuff many people told me it would work fine

 

did you get a resistor box and run the wiring to your ecu for the other 2 injectors?Also add wires to distributor?

 

ok yes i have the box and its wired in

i just heard it might be Crank Postion Sensor

 

yea that will keep it from starting for sure...
ckp sensor is in the dist... where did you plug the wire from the dist into the ecu?

 

that part my friend did i'll have to ask him

we did this as clean and OEM as possible so i'd asume where its supposed to be i know thats an *** anwser but best i can do sorry

 

bump please i'm really fucked i'm going to work on it more but any ideas will help

 

please id these some one

i think a new dizzy might be a help and trying that out still worried school starts Weds

 

TTT

come on all i couldn't have confused all you could I?

do i get a free EF for stumping the 4th gen group?

 

do you hear the relay clicking? if so check/clean your grounds.

 

I know this may sound stupid...but can on confirm it is not firing? Pull the spark plug out, have the wire hooked up to and it laying on the block, crank, see if it fires. Does it fire?

Next, can you confirm you have fuel delievery into the cylinders? Key on several times, remove sparkplug, and sign/smell of fuel?

Let is know that first, maybe we can help. I understand how it sucks too! I did an MPFI swap, first time unsucessful, it spoiled my week. Stick it out until the end, and get back to us with those answers.

Best of luck!!

 

Im going through the same thing right now , but mine starts and runs but really shitty.

Did you check for codes?

Im throwing 3 right now, and i know one is the crank angle.

Im to the point were im just gonna buy all new ****.

 

there was a ground issuse and its getting spark then dieing i really think its dizzy won't get fully started cranks fine though

other then dizzy what could it be?

BTW still no luck on naming those plugs

thanks for the help and hope more is coming

 

so it gets spark for alittel while then stops ?

have you checked your coil, check the resistance.

what is this relay you talk about thats going nuts, where is it ?

and waht are those 2 plugs for, i dont remember having any plugs like taht, in that area.

 

Ok I really still think its the wiring.

I'm acutally the one who dropped this motor in for him but I didn't want to do the wiring since I never owned a dpfi car for this reason.

He got a conversion harness off ebay, and he seems to think it should be plug and play and no other wiring is needed, I seem to think that there is still a bit of wiring to do. On the passenger side of my Si, I have 3 plugs by the fuse box, on his STD it has 2. But then on his conversion harness it has 4 plugs. Also, we didnt repin anything into the ecu plugs either, and im almost positive some of that stuff needs to be pinned.

Max, I really think you should try to contact the guy you got the conversion harness from and ask him what else is needed to be done to complete the conversion.

 

thats yoru problem. you didnt change the ecu pins around liek you were suppose to.

there is 2 sides to that conversion harness he bought. what did he plug the other side into ?

go find a mpfi swap guide and follow that. dont mess it anything else before you mess it up. put it back to stock and then start over

 

what do you mean two sides? Do you mean 1 side should go to the ecu? Maybe that is what the 4th plug is for on the passenger side, like a jumper harness that goes to the ecu?

That's what I'd do.

If this is just a DPFi to MPFi then I'd find a good guide, and there are plenty of them, and start over. I wouldn't use the conversion harness.
