2uz 40th anniv 80 - HELP

[jason89i]

40th 2uz.

Hey guys, newbe here. A few years ago I owned a 2003 v8 4runner limited. Wheeled it in colorado. Loved it. Unfortunately, I had to get rid of it. We needed third row. Bought 98 100 series….. hated it. The 100 was WAY too big for wheeling. Sssssooooo…..
I picked up this 40th, with the intention of mating a 2uz to it. Engine and trans are now mounted, most of the wiring is done, but now I’m stuck. Ive done some engine conversions on bmw’s, but this is the first Toyota I have ever worked on.

I need your help!!!!

But first, some pics and history.
Here is the rig.

Pulled the seats, carpet and most of the interior junk. Massive cleaning was needed. It was about as disgusting as you could imagine. Chew spittunes spilled all over. Here is a pic of the before / after cleaning. Can you spot the 12"x12" spot that was not cleaned?

Motor fitted

Here are the specs:
2005 tundra 2uz-fe (w/ vvti) (without security)
Engine harness was never separated from engine
Engine mounted 6” forward.
A750F 5-speed trans from an 06 LC.
Custom driveshafts
Customized SC pan.
Custom trans mount
Custom engine mounts
2-1/2” custom exhaust

I have a completed spreadsheet for all the connectors and made my mating harness.
05Tundra – connector IE1 (main chassis / engine connector.)
05Tundra – connector J28/J29 (junction for trans gear selector indicators.)
05Tundra – connector EB2 (start sig / air pump / alternator.)
05Tundra – connector E3 (A)
05Tundra – connector E4 (B)
97 LC – IH1 (main chassis / engine connector)
97 LC – IH2 ( gear selection to comb meter. )
97 LC – E7 (D) (from dme to chassis.)


PROBLEM
Here's where I need your help. No-start. I am getting no spark when I try to start. It has been sitting there since May, I am completely stumped.

QUESTIONS:

• EDIT.......I DO have the Leak Detection Pump installed or wired.
• EDIT....OOPS, I DID HAVE THE ALT HOOKED UP.
• I have the start request signal (from st1) going directly to the starter (bypassing the p/n switch.) Will this cause a no-start?
• EDIT........I DO have the air pump installed / wired .
• EDIT.......I DO have the air injection driver installed or wired. Is this required?
• EDIT.......I DO have the DATA LINK connected. powered up, but not communicating w/ dme?
• Does the ECU need to be “reflashed” due to the non a440 transmission?

Desperately need some help from others that have done this. Rob???? Toojayzee???? Anyone???? HELP.

Cheers, Jason

Shoot a PM to Waggoner5. He dropped this engine in Project X (His FZJ-45)...he'll be able to help.

From what you are showing as installed and not installed, I would look at the 05 Tundra and see if it had anti theft with the the factory key having a particular value of resistor embedded. The ECU sees this value when the correct key is installed in the ignition. This is assuming that all of the wiring at the ECU is correct of course.

Thanks for the quick reply. (by the way, your rig is off the charts. ) I was wondering the same thing. (similar to the bmw ews systems. ) I took the dme to the dealer, but they needed the vin. couldnt find vin. so back to the drawing boards.

I could not find any imobilization on the 05 wiring diagrams. However, on the 06 tundra 2uz's, the imobilization goes to ecu connector E4 .... pin 16, W/G, IMI.... pin 15, P, IMO.... pin 35 LG, EOM. I have none of those on the E4 connector. Did not see any dme pins that went to any a key transponder. maybe im missing something. Totally stumped here.

So if it was similar to the BMW EWS system, and saying that the DME and EWS are aligned. wouldnt you be able to just re-program/calibrate the key to the DME/ECU or anti theft control module, that came with the motor? I know that bmw's have a button sequence that reprograms the key...

I really dont know. I dont have the key, transponder or vin from the truck. Guy i bought it from swore it had no immobilization. who knows at this point.

bmw's had 3 types of ews. ews1 requires a chip and clip one wire....ews2, dme needs to be flashed....siemans dme w/ ews3, has not been cracked yet (legally here in the US.)


here's what ive found so far....

06 tundras
connector t19 goes to the transponder computer.
dme connector e4 pins 15, 16 and 35 go to the transponder.

my 2/05 tundra harness (with matching dme) had none of those. the tis wiring diagram for the 05 tundras does not show those either. it does not show any immobilization systems. was there another type of immobilization? is there something im missing? at a total loss here.

i have another pre 3/05 dme i should receive by friday. will verify w/ dealer the options installed with the vin. hopefully this will rule out immobilization.

cheers, jason

if it doesnt have an immobiliser (which I believe in 05 (you sure it is not an 06)) it should start off the key. Sounds like a power or grounding issue to me, check all your wiring again. There is a relay for the ignition which feeds into the coil circuit shown on my landcruiser diagrams

I'm pretty sure you need to have a wire from ST2 of the ignition switch to STSW of the ECM, then going from STA at the ECM to the starter relay.

Hopefully, you have the EWD available for the Tundra so you can see what I'm talking about. There is also a difference between engine controls for the regular/access cab models and the double cab.

Don - I think you on to something here. I reviewed my xl spreadsheet. I did not have the ST2 12v signal going to dme STA nor J28/29...... i thought it was a ground leg for tripping the starter relay...... WRONG.


2005 tundra ewd611u page 106-107
M/T - ST2 to STRY (both hot leads.) STRY ground leg to TVIP ECU to grounding clutch switch. (it appears that the "toyota vehicle intrusion protection" ecu allow a direct channel for the grounding sigal to pass through the tvip ecu.)

A/T - ST2 to TVIP ...... (note its not a ground leg for the a/t trucks, its a 12v start signal.)..... then to junction j28/j29 then to engine dme STA and NSW (neutral switch.)

ooooohhhhh i hope this is it.

oddley enough, there is a typo in the ewd.
2005 tundra ewd611u page 107 (starting chapter) shows the pink "start" signal going to (A) e3p15. WRONG (that is actually the g/w wire for STP stop light switch as seen on page 126.) the pink "start" signal goes to STA (C) e5p11 as indicated on ewd611u page 123.


sigh.

If i go to the shop over the weekend I will post results........ hopefully a rumbling v8.

Don, again, thanks.

cheers, jason

You need to look at page 324, it seems as though you have an ECM/Harness from the Double Cab. These only came with the 2UZ-FE, not the V6, and only came with automatic transmission. If that's the case, make sure you pay attention to which EWD section you are referencing, since there are other differences.

Once you are hooked up through the ECM, you should have the "cranking hold" feature. With this all you do is push the key to the start position and the ECM cranks it till it starts, or it times out.

I also wondered if you can find a VIN tag on the transmission somewhere. I've noticed them on front wheel drive Toyotas, but haven't looked yet on the Tundra.

 

[Skrewball]

two simple suggestions.

you should be able to get the vin using a quality obd2 scanner. If you hook up the dlc.

and sometimes easily over looked......do you have the mass air flow plugged in? on the 03 engine i worked with it had to be plugged in to get spark.

good luck!

thanks once again.
i checked out the "double cab" section. sigh. might as well re-do my entire wiring xl spreadsheet. there seem to be MAJOR differences.... like the "start" ..... tvip.... who knows what else.

thanks, i need the luck.

yes, the afm was hooked up. not sure if i have the dme even powered up to communicate through the datalink connector.

will verify and modify my wiring "hopefully" this week and post any progress.

[jason89i]

Got the vin number from the previous owner, checked with toyota....it was an access cab and it DOES have IMMOBILIZATION!

aaaaahhhhh.

So how does the dme see the correct key? I cannot find it within the 05 tis wiring diagrams. is it through the tvip or integrated contol panel?

anyone have a good source to buy an 05 dme w/o immobilization? jason

 

[jason89i]

now i am completely confused.

as stated earlier, the toyot service dept said my vin HAS IMMOBILIZATION.

just now i had the parts dept run the vin of 6 different dme's. NONE HAVE IMMOBILIZATION including my vin. all build dates from 4-05 to 7-05.

soooooo...... how do i know for certain if it DOES OR DOES NOT have immobilization.

 

[SuperRunner]

Go back, and have them print out the spec sheet for the vin. It will have EVERY option that the vehicle was sold with.

As for wiring in the imobilizer, it uses the TVIP. It would be a single wire. I will look over the wiring diagrams tomorrow and give more detailed info.

Does the ECU need to be “reflashed” due to the non a440 transmission?

Leak Detection and Pump are REQUIRED
Air Pump is REQUIRED

If these do not work, your throttle will not open all the way.
If you have the Data Link, but no communication, then you do not have power to the proper spots on the ECU. What type of scanner are you using. A dinky code reader will not do the trick, you need an actual scanner. I got mine from harbor frieght for $100.

Non a440 transmission? huh? Why would the 2UZ ecu care about a missing A440, it needs the A750, which you have.

 

[jason89i]

thanks rob -

will get a good scanner.
have a leak detection pump and air inj driver on order.
I also have the original key coming in the mail. (will be interested to see if it has a chip.)
will ppost result when they come in and i get it wired up.

cheers, jason

 

[SuperRunner]

you may or may not be able to tell if it is chipped.

You really should get that printout to be 100% sure.

Yeah, that leak detection pump, all that has to be working or the throttle won't work. That means that you need to get the charcoal canister which has a small motor and a pressure sensors that pressurizes your evap system. WOHOO, the FUN!!

 

[ToyotaDon]

PM me the VIN, I can check it at work.
