ED with D15B7 injected wiring help

[tseesinngwailo]

Hi All,

I have put a fuel injected D15B7 in my ED and have an ECU marked
37820-P06-Q50

i have a wiring loom from an EG sedan and have wired things up to see if I can get it running. I have not wired in the PGFM relay and according to the few diagrams I can find on the internetz regarding the P06 ECU, think I have everything needed.

I can get spark when the car cranks, and I know I have fuel pressure, but it just wont start, or run.

Has anyone done this conversion before? I am sure I have something not wired correctly, and I really need to get this car on the road.

Can anyone point me in the direction of some good wiring diagrams that show what pin is what on the ECU, and being connected to an auto, is there some wires i need to connect to make it think its in park etc so it will allow the engine to start?

Any help greatly appreciated.

Peter has already given up some of his time to help me today, and i went from no spark to now having spark (thanks Pete) but I am just stumped.

Plese help me ECU-Wiring legends!!!!!!!!

Also happy to provide BEER, FOOD, or whatever (some cash) if anyone wants to drop in and have a look what I am missing.

Cheers

dizzy wired correctly ?
Fuel pump primes....but does it get to the fuel rail ? (crack the fuel line at the fuel filter or at the rail itself slightly to see if its building pressure - fuel will piss out)
PS check this out

yes,check the link ben gave for ecu,
u will have to provide a ground input to pin B7 to fool the ecu into thinking shift lever is in park or neutral.
i take no responsibility for this method,i dont know if your carb shift lever will have the switch on it to do it properly,but u could maybe source a efi shift lever with switch from an ED or EG maybe if u choose to do it properly.

u may also need a brake switch input to ecu as well on D2(12V input) for it to start,just tap off the load side of the brake pedal switch to do it.

that..on a OBD1 auto to manual conversion you take the large single loom located right at the shifter - and directly connect the 2 x Large wires in teh middle , and then connect the reverse switch wires direct from the gearbox to the above mentioned loom to get your reverse lights working too - kinda looks like this

2 large wires are the starter motor feed ben,if the car cranks now then they must be connected or its a manual loom,or am i not reading that right & car is not even cranking?

if its not cranking then good start is what ben said to solve those 2 issues,but u'll still need the ecu ground input as well from shifter.

Hey Guys, Thanks Ben and CRXer, at least I now have some better diagrams to look at..

I have temporarily connected everything, I am just trying to get the car to run before putting everything where it should go.

This is what I have, the loom on the engine has all the right plugs etc



The car cranks fine, it sounds as though its trying to catch, but just wont do it.

I know i have to connect it to the shifter and all, but want to hear it running before continuing.
I have spark, thats definate, not sure , but it looks strong enough.

Covered my driveway in oil before finding that there was no oil pressure sender installed AAGHH lucky it was old oil



I think I am maybe missing a ground or safety interlock maybe

I have connected the ground (to simulate shifter) but maybe its the wrong wire?

There is no solenoids on my gearbox, so i have a few plugs not connected, not sure if they should be joined to make a circuit?

At least with your help I am getting there.

Cheers

The only solenoid on the gearbox is the reverse light switch , won't stop the car from starting. Checked you haven't blown a fuse under the dash when trying grounds or other wires ?

That's what I said! I don't know how many times I've had to search every fuse before replacing one or two when I've been doing the wiring.

Oh yes, I forgot to say, i did find the 50A fuse in the under-bonnet fuse box was blown, probably why I didnt have spark to begin with, and being an electrician for 15 years, I kicked myself for not looking at the fuses first!

There you go! Bl**dy electronics! why can't they make cars without wiring and all this electronic stuff?
