I thought so, thanks! (wasn't sure where it got it's power for the starter solenoid). So the key powers the coil in the relay, the NSS grounds that, then power then goes threw from #30 to 87. ...?

Or do you happen to know...does the NSS signal the ECU to ground it, or can ether of them ground it? (in a Renix Jeep)

Funny to find it's the second one back, I saw a diagram that had it at #3.

 

ECU grounds it on # 85.
NSS only affects ignition power to the system.

 

Ow CRAP! I'm sorry Josh, for confusing things..I got off on the starter relay, (which is grounded by the NSS, and never the ECU) Mostly just added confusion.

The ECU, and I believe only the ECU grounds the fuel pump relay. (unless you do it).

 

What is the nss

 

Neutral Safety Switch, mounted on the passenger side of the automatic transmission.

 

Can thr nss go bad and if so will it cause a ffuel system not to work

 

Yes it can go bad, and no it will not cause your fuel injection system not to work.

 

Re-read Post # 15. Start tracing back from where you found low voltage til you find where it's getting lost. Don't be afraid to open up the harness to trace it. It's easy to put back together with electrical tape after you fix the problem.

 

Ok so I have traced wires and traced wires. I think I may have a bad computer cause all my wires are good as far as I can tell.



My next ? Is could I convert my motor to carberater. Is there any intake that would bolt up to my head for a carb.
I have heard of other poeple doing it with diffrent motors


I know I would have to have a new fuel pump or fuel regulator to get down to 7 psi

 

Seems to me just getting power to that #30 spot would be a heck of allot easier than modifying the whole fuel system.

 

Was looking. It seems to be a red wire to the #5 spot on the diagnostic connector. OK, went and looked, that's the middle spot of the one with 6, on the engine side. (and my #30, nearest the engine is hot with 12.7V as well)

 

I have trace all the wires to to proper locations u should see my engin bay there are wires everywhere. I even got a wiring diagram amd dummed all the points that should have power I am getting no where and need my jeep

 

I can see how that would be a pain. Mine's sort of a mess. I just looked some more, mine has a two wire plug right there, high on the passenger inner fender. The top of the two, red w/white stripe is that wire I think. Looks like that might be where the fuse link attaches to the wire to the relay, (and stuff). I can't be sure without getting farther into it. Do you have that plug? If so is it good? Do you have power on that top red/white stripe wire?

 

this might help trace wires..http://jeep.zerok.ru/index.php?page=124

 

Ok so I have traced and replaced a bunch of wires in the past 2 days. And I heard the jeep run today for the first time in 2 months.

The only problem I am having a fuel injector prim problem once it starts they run fine do u have any idea what would cause this
