Well I am debugging my setup with the E6X on my 89 Turbo II with a 13BT in it. In a earlier post I posted about not having ignition and figured that out being bad wiring to the CAS (Go figure, it still showed RPM and Inj duty cyl on the Haltech)

Anyway what I have now makes no sense what so ever. The rails have fuel pressure (noted fuel leaks I had to fix when I first keyed the car on). The haltech shows injector duty cyl on the gauge screen, you can hear the primaries clicking, hell I un hooked the injectors and hooked a fuel injector harness tester (it little light bulbs that plug into the injector clips) they light up the way they are supposed to.

The madness is that I motored the engine over at least 20 different times today, pulled the plugs and nothing, no fuel, injectors are brand new, we all know if rotary doesn't after that many tries and gets fuel its going to be flooded (I so wish my car was flooded right now, I can fix that)

I fogot to messure the voltage going to my injectors. How many volts does injectors have to fire? I hear them clicking, but its it posible to "halfway fire" I plan to look into this angle tomorrow.

The other thing it could be is bad injectors I guess. All 4 of my fuel injectors are brand new though.




Thanks

 

The fuel injectors and coils + side is wired through the same circuit I believe.
It goes through the 10A(?) fuse and relay which is switched via the ECU + switched ignition.

Checked all fuses, fine. The car has no problem with spark now, just it doesn't get any fuel.

 

Check the comm proggie to make sure the fuel ISN'T disabled?

Fuel is abled. Just checked injectors leads. The Haltech is puttig out DC voltage to injector 1-4 which should be a ground. All 4 injectors gets its power from the Red/green striped wire, which goes to the 10 amp fuse, at the fuse I have ~12 volts on both sides of the fuse. So I decided to take my wiring out of loop that I did. I diked Inj1 though Inj4 in middle of wiring harness so only thing in the path is E6X its self. Interesting results, Inj1 had 12 volts on it, Inj2 had 3 volts, Inj3 had 3.6 volts, and Inj4 had 2.6 volts on it. Only two things I think is the harness is pinned wrong or injector drivers are fried in my E6X unit.


Anyone have the pin outs for the E6X so I can trace my wiring back to make sure my wriing is fine. The wiring diagram from Haltech makes no sense. Injector 1 says 19 on the diagram, is that pin 19? I counted the pins every way I can think of and 18 is the closest I can find.

 

Actually, I think the setting needs to be "disabled"?

I talked to Haltech yesterday, I think I have it figured out. It will be later this week till I get a chance to mess with it.

 

so what did you find ?
I was going to post a question which i think is close to the problem you were having.
I cant tell what inj1 inj2 3 and 4 are to be wired to, it doesn't say anything in the
instructions that i can see.
I would have guessed that 1 and 2 are the Primaries and 3 and 4 would be the secondary?

Yes, Inj1-2 for primaries, Inj3-4 for secondaries. In the main X manual on section B.6 Rotary Engines it states how to wire up rotaries, but it says that INJ1 goes to primaries and INJ2 to secondaries, but this is probably talking in fuel channels, or its wrong. The correct way is how we've stated.

Eventually in the E6K manual its correctly documented.
