Changed HG, now starter won't crank?

thenderson2011 · 08-12-2013, 04:26 PM

This is where I have my grounds wired in, is this a bad place? Also do I need to have them grounded separately?

I also came across this wire, it's blue and black, but I have no idea where it needs to go, any ideas?

Where is this wire located?
Is it under the intake manifold?
Are you positive that both wires for your starter are connected?

I ask because the TEWD (wiring diagram) shows a Black wire with Blue stripe as the wire that engages your starter solenoid. The original connector is not an uninsulated female spade type as the one shown in your picture, but if it broke in the past someone may have replaced it with that as it will work for that type of connection...

As far as I know, there shouldn't be any problem having the grounds grouped together. There should be several there, as Toyota used that spot as a ground point for several systems.

Looks like the starter solenoid wire to me too.

That's not the correct placement for those grounds but it'll work fine. They have their own boss where they connect on the intake manifold a little further back where nothing else attaches (that may be it in the picture) and I believe Toyota specifies a special fastener for it (certain alloy with two or three stacked washers pressed on it). There are circumstances where you cannot ground all lined to the same location (for noise reasons) but those are fine.

You guys were right, it was the starter solenoid wire. The plug in was a bitch to find but I found it. Now I'm not getting spark and the tach doesnt bounce when i try to start it. I'm going to try and move the grounds to the spot they're supposed to be and see if that changes anything, because it started fine before i took the motor apart.

As long as the grounds are clean and well connected it's not your problem. Make sure the grounds on the passenger side are in place as well (can't remember if there's just the one chassis ground there or if there are others from the ECU harness.... I've worked on too many aftermarket setups which also use that ground point so I can't remember the specifics.

I'd start with inspecting the CPS' harness and making sure the mechanical timing is set properly.

thenderson2011 · 08-13-2013, 07:23 PM

Alright. Would the cps wires cause it to not get spark?

thenderson2011 · 08-14-2013, 12:42 AM

Ok so i fixed up the cps wires and got spark. It started to turn over and then died. My uncle said he thinks its the fuel pump not kickin in because we couldn't hear it turn on. I need to getA paperclip and I'll check the diag box and see if its getting power. If not what willi i need to do?

Of course the CPS would cause a lack of spark.... It's what the computer uses to tell it WHEN to spark and how fast then engine is moving and which piston is ready to fire.

The fuel pump doesn't run if the ECU doesn't see the engine turning. It's a fail safe. On the non-turbo models it's tied into a physical sensor in the air flow meter but on the GTE I believe it's dependent upon a 'valid' signal from the CPS.
