Hey guys.. i'm havin a problem here..

tryin to resolve this.. heres the symptoms

Application: 91 Teggy (LS-vtec with OBD-0 to Obd-1 wire connecter harness)

1. Got Good spark
2. Got fuel pressure at the rail
3. new RC injectors (obd-1)
4. Resistor box loop back harness installed to eliminate box

*No injector pulse..

no idea why.. any suggestions?

does anything special have to be done to the injector wiring :dunno:

 

ok i've got an update here..

realized that the resistor loop was pluged into the wrong spot.. & now that it is corrected.. we are getting fuel through the motor.. i can definatly smell it comming out of the turbo mani..

we are now getting a slight spudder.. she wants to start sooo bad.. but just won't.. so in my head i was thinkin firing order.. checked it & it's right..

Got Fuel
Got Spark..

struggling with this..

someone comment .. come on!!!

 

do you have the injectors wiring harness backwards.....I did it on my roommates swap and then realized I had to turn it around......so like if you are facing the motor and it is injectors 4-3-2-1 put 1 on 4 3 on 3 etc.

 

ok i'm slightly confused by this comment.

we are using the stock engine harness.. are you saying that we have to flip the injector plugs around into reverse order?

if so, please explain why!

 

ok...you know the injector clips how they are in a line...sometimes you bring it in from the wrong side of the motor, thus you hook up the clips to the injectors back words.....so isntead of the injector clips being clipped 4-3-2-1 they are clipped 1-2-3-4 this would make the injectors fire at the improper time compared to when the motor was on its firing order...thus why it would sputter and pop and want to start but not.

 

brought it up from the drivers side of the intake mani.. ?

 

I'm havinf the same problem, and mine also is brought up from the drivers side intake manifold....

 

i went back out to the garage last night & took care of the vacume system.

origially didn't have any of it hooked up. but now it's all there & we're sittin here with the same resultz

The thing that is really messing with me is the GSR head on the motor (ls-vtec) coz it just changes a lot of things. I'm sure it's got to be something stupid that i'm over-looking, but i havn't figured it out yet..

someone toss me some more ideas that might trigger somethin.. thanks

 

Solved the problem!

i put the stock injectors in this thing & it fired right back up.

we're gonna have to wire in the special plugs that came with the 750cc RC Injectors that we are using (obd-1)

 

Interesting.
