Rebuildstill going on

Hello everyone,An update on the truck rebuild, got the 4.7 L motor in after the rebuild ,now to work on the electrical system, have power to the starter, but that its! If any ideas out there please let me know. Will be working on it again in the spring as my sister's house has mold in an doing a full restoration on it.

 

If you pop out the starter relay and jumper the appropriate terminals, does it turn over?

 

No itdoesn't and I have check the starter and the starter motor moves in and out so I don't believe it's the starter but I have no power showing at my fuse boxes at all and no ligts inside the door and have check all fuses are good. Do you have any other suggestions?

 

I would need to look at the EWD to track down what all it passes through to release the circuit. Or read the FSM which is free for download in the 'so you just bought a 1st gen?...' thread to see what diagnostics they tell you to run thru. I'm neck deep in something else at the moment and can't look.

I assume you've checked all fuses next to the battery, including the two MUSB I believe your DC should have, the box window'd fuses etc.? (Again, I can't look)

More details too about the engine itself ... same engine, just rebuilt and reinstalled and now it doesn't start?

If your truck is one of the DC which had immobilizer, or it has a factory alarm or remote start installed at any point, that may be a factor also.

Finally, you tested the battery for CCA (not voltage) correct?

 

Having just re-read thru your initial thread.... I picked up this 2004 for $550 | Toyota Tundra Forum (tundras.com) and the other 3 related threads, have a few questions in case I missed something.

This is the same 2004 DC you bought for $500 ?

You or someone re-built the engine or you put another re-built engine in ?

The thread started on July 23 with the pic of a main harness 82121-0C021, did you put another harness in after the fire ?
Hello everyone, been a long time since I have been here | Toyota Tundra Forum (tundras.com)

I would start at the main fuse box and check for 12vdc at the red circle and visually check the 140A ALT fuse(red square). If the 140A ALT is blown, steps for removal can be shared(can't pull straight out). Those points are the first place the battery voltage goes to before branching off to other places.

 

There he is! Welcome back!

 

Thank you for the help and the battery CAA is brand new at 750 CAA, once I'm done with my sister's house restoration and if it's not to cold up here in northern Canada I willget back to working on the truck again.Thank you again for the information.

 

Hello It;s been a while and Thanks so much for the information,, here is where I am so far, Have rebuilt the engine wire and the battery cowl wire is where I am stumped, from my postive wire I get continuity to my starter and the post wire on the fuse connection tones down to my generator (alternator) then the connection off of my generator I get contnuity to where the plug goes to the fuse box connector, I have also checked all my fuses and still have no power at the ignition and at the ECM nothing of power at 9-12V.
Any more suggestions would be apprecaiated.

 

Where did you actually check for voltage at the "ignition" and "ECM" ?

At the Ignition Switch is a 6 pin connector I23 and with no key in ignition there should be 12vdc at AM1 pin 1 W-L and AM2 pin 5 W-R.

If you do not have 12vdc at those 2 locations, you need to double or triple check the 40A AM1 and 25A AM2 fuses.

 

Thank you for replying, What I actuall need to know from what I previous wrote is with hopefully my explanation is do you think there's a problem with my Battery cowl wire? or maybe my Generator ( Altenator)?, I'm actually testing the 140 AMP fuse and am getting 12. 86V There but will be replacing as the shield case is damaged also I have tested at the ECM but no 9V to 12 V as my service manual says and also at the starter I'm also getting 12V there. I have the battery cowl wire out right now and seeing if there's any shorts in the wire to fix it and have check on the conitunity from the 6 prong plug to where the ECM plugs go and the conituity is good but when I had the battery cowl wire in before had no voltage at the ECM I'm replacing the 140 AMP as said and will be changing all fuses for as fresh start and will post again if problems.

 

[ATTAThis what I found on my battery cable that goes to the carberator then to the sensors so far CH=full]1130840[/ATTACH]

 

So if anyone has the schematic or a diagram of the battery wire I would apperciate it

 

Our trucks don't have a carburetor, do you mean the throttle body?

Either way, it would appear someone's been hacking in there. If you haven't yet checked the wire bolted (with an L-bracket on my truck) to the top of your positive terminal, and verified it's complete all the way to the alternator, you may want to do that.

 

Wiring for your 2004 is here: https://www.tundras.com/attachments/2004-tundra-ewd567u-pdf.543920/

 

OH sorry I didn't mean Carberator, I meant the starter wire that I found and another problem I found is the one that feeds power to the ECM theres no split of of the postive wire or back from the generator

 

Hello, since I had to replace my wire harness and the battery wire I'm rebuilding and since the last pictures I sent on here I think I might be, staightened out a bit and memory from the tear down I did two years ago, Finally that there was a wire on the negtive terminal that went the body for a ground and as I have to rebiuld the wire I have order a knock sensor wire that will come off my harness wire instead of the hack job that someone from yers past had done, What I do not remeber is though which fuse I see that the 140 Amp may go to the positve side but I get conflict information that it maybe the 60 Amp that goes to the positive also with this wire of pictures thatI'm posting I have already tied in the negative side but the cut wire that shows I;m still not sure if there should be a jumper connection ther for a snsor and the starter relay.
Any advise would help Thank you

 

Never mind I figured it out

 

Forums work better when folks follow up with what they actually did to fix the problem !

 

Please share with the class for future searchers so the solution is known.

 

@jmohn6 any feedback on what the solve was, so others can benefit?
