Need some brainstormers........RB25 No power

[tek747]

Plugged M63 and ECU today, and come to find out.....................No power to ECUNo power fuel pumpNo power to ignition fuse! AHHHhhhh!!Why!? Ive checked all the fuses and they are all goodI have voltage on my ignition switch, but cant trigger the starter, WHY?HELP ME. HELP ME HAELP ME HELP ME

[Coolwhip]

was the car originally automatic?

[Darius]

Do you have power at the switched sides of the IGN and ECCS relays?

[tek747]

YES the car used to be an Automatic (hmmm!?)

I do have power to both. ( I think!)

There are two relays on the RB25 one is the eccs and ign, i used a voltmeter and it displays voltage. The fuel pump relay.... displays 3.2V in the on position. Could it be a groung wire that i missed? Ive hered something about auto to manual but, when i got the car, it had allready been swapped and im just replacing the 5 speed KA!! Dude this really stinks. I think im on one last brain cell!!! I have not slept and im gonna get fired from work. LOL

[Darius]

LOL don't get fired or you won't be able to support your baby RB!

First thing to check, since the starter is not kicking over and your car used to be A/T, is the top plug or 2nd to top plug next to the fuse box in the engine bay. It should be jumpered to itself. But like you said, that should have already been done during the 5 speed swap.

Next, try running a jumper wire from the orange wire on the ECCS relay (coil side) to ground. That will manually cause the relay to close and power up the ECU. Try starting it that way.

[Coolwhip]

beat me to it.

[Darius]

Got quick fingers. Just ask yer mom. LOL jk Sorry that was unnecessary and totally unfunny.

[Coolwhip]

bastard, lol

[tek747]

Ok thats crazy! Both you guys are offline and then BAM! Online then off!!Crazy fingers............... will try be back in a few!!

[Darius]

I am on and off all day while at work. Keeps me from hating my job and making my coworkers look bad with how little some of them do.

[tek747]

before i leave...........Coil side?? Please explaine.

[tek747]

Your a lucky man!! Iget to be out in the heat all day.

[Darius]

before i leave...........Coil side?? Please explaine.

On relays, there's a coil side and a switched side. When one side of the coil side has power and the other is grounded, current flows through it drawing the other half of the relay to close/open (depends on type of relay). When the switched half closes, power is transferred to the unit of interest. By manually grounding the coil side, it closes the switched side and you have POWER! For some reason, the coil side wire is not grounding out.

This is a dumb question, but are your relays in tact?

[albdrift]

Hey I t Sounds like your ECU is not powering up.

[tek747]

This is a dumb question, but are your relays in tact?

What do you mean in tact? I have spliced a w/b wire to the supposed pin#17 on KA harness along with the R (ign) wire both coming out of the relays fur power! I got good power to them as it seems! Im going to bounce my head of a brick wall .... be right back!

[tek747]

OK!!Ive got my fuel pump going! YESSSSss! Since i took my ignition completely off and runs by a push start button and switches, i had to reconnect two wires to my batt. in turn gave me the Voltage plus some tunes, yeah!Now the downfall of it.......... I still have no starter signal! (Damn them damn every singl little freakn' wires!!) Plus my ECU wont turn on!! (Geeze!)

[Darius]

Alright I'm going to put this as simply as I can...

Temporarily splice in a wire to the orange wire on the ECCS relay and ground the other end of it. ECU should power up.

[tek747]

no power......

[Darius]

I am fresh out of ideas if you couldn't get it to power up manually. Sorry man.

[tek747]

OK...... heres the verdict! On Saturday, May 10th of 2008 approx. 12:30pm (EST) Car came to life!!! I AM ONE HAPPY SON-OF-B!+@#. She purrs ever so nice, EVERYTHING payed off damn im glad. I would like to give everyone props that took time to help me out. My hats off to you gents!!!!!!!!!!!!!!

The problem: Nothing, had all wires right, found home for those 2 wires, had Fuel pump reversed.

Changed sprk plgs, added fule treatment, fuel octane booster, and fresh fuel. Pressuerized the system, gave it a couple cranks and Ba-BOOM, rrrrrrMmmmm,RRrrMmmmmm all is perfect! Just need twin cooling fans and and bleed the brakes! Thats it!

[Coolwhip]

Thats good stuff man, glad to here. Lets see some vids!

[Darius]

Sweet! Congratulations man!

[tek747]

I will have some footage here and on myspace soon!!
