NA Injector and possible wiring fault


Spike3.0

Recommended Posts

I'm hoping to narrow down on what's going on with my Supra.

 

I bought it a few weeks ago and a none runner, and after a bit of messing around and the help of fellow member russ-unsworth we got it going.

Currently the car will turn over but won't fire up - unless easy start spray is used.

 

When the car does run the engine is rough and it sounds like the injectors aren't running right.

I've since found out that the previous owner replaced the injectors believing this to be the fault but it didn't make any difference.

They think it was something to do with the wiring?

 

Before I go off and buy any un-needed parts does anyone have any ideas?

 

Also I couldnt find a NA wiring diagram, a link would be great!

 

Cheers!

Here's a couple of pics.

 

Ignore my blue scribbles and don't look for a variable resistor, because when Mr T. wrote the Supra Bible he forgot that it doesn't have one. :shrug:

 

(If anyone has a link to non VVTI GE EFI & Ignition please send it to Steve, both Club archives and members would benefit from the info.)
