ground problem
Grounding problem we have done a 12a to 13b swap with some up and downs . a Friend came over last nite and we believe that the injectors and not grounded thus not working the harness came with the engine and was cut out . can someone help with the correct ground wire se can get him on the road again. Thanks for all the help pics help us new to rx7.
|
What year block did you put in? Need more info.
|
the moter is 13b 1985 as well as the ecu and harness
|
Ok so is the fusible link for the fuel injection good?
|
yes we are good on the fusable link we got that done last week fro rx7 doctor. he has been a great help. the only problem is the fuel is not getting in the engine.
|
there should be a ground wire with an eyelit on it that should be grounded near the rats nest. its one wire with the eyelit. that wire is for the injector ground. i had teh same problem and found the wire. problem solved. how bad is the harness cut?
|
The harness was not good or bad as we have learned the had way but if we get this ground figured out i hope we will get it off and running . happy day i wil have my son do pics when he gets home. thanks to all
|
the only problem is the fuel is not getting in the engine.
So are you getting fuel to the rail? Tested the fuel pump and the AFM? Let me see if I can take pics of my engine for you. What part of the wiring harness are you having issues with? |
yes all has been checked the fuel rail is full of fuel when we take off the injector gas comes out of the rail. pics would help us out
|
digicam battery is being charged right now. Does the ECU have a ground to it? I know some models had a ground strap. I'll take a look at mines too.
|
no strap on the ecu when son gets off work will have him send pic of what we got thanks to all.

I checked all my bolts on the rat's nest on my SE and found 2 wires grounded to a bolt. here are a few pics. good luck... wow these pics don't look too good. let me try again.
these are alittle better. but that's where you can try looking for your grounds.... |
no photos came in the email also do you have a relay called the main relay that is on the drivers side that also controls fuel delivery . thanks
|
what is your e-mail addy?
I don't have an extra one. |
can you possible take those photos over again can you take them again im going out to take the photos of my harness so you'll can see everything
|
let me get your e-mail addy so that you can see a better picture of it
|
|
My grounds are on the otherside, but they look like the same ones....
|
Do you have the ground from the big loom on the driver's side hooked up? Mine is bolted with the main negative cable from the battery to the strut tower with a 10mm bolt
|
what are those two white/yellow wires running to your upper fusable link? My car doesn't have those.
|
those are for the injectors and ignition I think

my pics aren't great, but it's a small ground coming from the wire loom that goes to the fusible links....
|
I'll be back. I want to put my car together before it gets dark.
