Ok so is the fusible link for the fuel injection good?

bugman1973

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?

bugman1973

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?

bugman1973

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.

bugman1973

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....

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.

RXnos1200

iTrader: (24)

those are for the injectors and ignition I think

bugman1973

tracnoid said that i needed those to get the se engine to work they supposedly go to the injectors and the computer ones just white and one is white and blue.

bugman1973

can you possibly get a photo of these i dont know what this is

RXnos1200

iTrader: (24)

my pics aren't great, but it's a small ground coming from the wire loom that goes to the fusible links....
