im trying to help my friend with his swap and i just realized that i might find more help in here from the specific ef owners. here are the facts:

ITS NOT THE DISTRIBUTOR

d16z6 into a 91 dx

using d15 harness, using obd1 p28, with new obd1/0 conversion harness.

it cranks but doesnt start up, no spark

fuel is perfect (MPFI wiring done correctly). removed fuel rail, cranked ignition, injectors fire in normal sequence.

the distributor is perfect, just pulled it out of his brothers running z6 motor.

i thought it was the wiring at the distributor, but all his wiring seems to match the info i found here on h-t, with one exception: his directions have the orange going to orange, and thin white going to white, where my directions say to run the orange (harness side) to white(dizzy) and thin white(harness) to orange(dizzy side).

after swapping those wires, still no spark, so i switched them back, but which is the correct wiring for that??

i dont see anywhere else the wiring could be wrong, the swap is too simple.
his grounds seem intact etc...

as far as codes are concerned, when i put the jumper in and turned the key in the on position, it just blinks a single pulse constantly, no real sequenced codes like i expected...

im so lost, this doesnt make any sense. i can do an h22 swap from scratch and have it start up on the first try, but i cant figure out where this guy went wrong on his simple d16z6 swap.... i wish i was there from the begining...

forgot to note:

he left a few plugs "un-plugged" like the fan switch/temp sensor/tps, but i thought it should still start up without those and run like crap... should at least be spark.

 

orange to orange and white to white is correct - try switching the 2 white wires

 

agreeded. switch the 2 white wires.

 

alright im going to have him try and switch the white wires,

but is there anything behind this theory or?

i checked the wiring, and it has the individual (larger) white wire going to the green/yellow wire on the distributor, which i thought was correct? and the thin white(grouped with the other wires in the harness) is going to the white wire on the distributor...

isn't this already correct?


i guess theres nothing to loose at this point, but it won't ruin the distributor or anything if switching the white wires is a wrong move?

 

won't hurt anything, but if the thicker white is connected to the yellow/green it is correct and you don't need to try it - just that sometimes when switching connectors some people get the white wires mixed up

oh i see.

yeah like i tried explaining in my first post, i've already inspected all of that easy stuff.

the white wires are most definately correct.

if the reason for the car not starting was that simple, i definately wouldn't have needed to make this thread.
