On mine the White/blue wire is the B+ feed. That has power? Also, there was a black/red wire (ign2) that powers the injectors, and the coils I believe. that has power as well? When cranking as well?

 

Yes those both have power. Not sure when cranking, I'll have to check that

 

The white/blue wire that's coming from the harnesss? I have the b+ wire going into the ecu terminal b+. That all that needs to be done right? Or is there wire from the harness that goes with them?

 

Well I have good compression in all cylinders. Took plugs out and cranked over, no fuel, no smell at all. I can hear my fuel pump!!! So my injectors are not letting fuel in! There must be a wire from the 01 taco ecu that's has to be hooked up that I havnt. Diving me nuts!! Been weeks on just wiring all day! Goin over and over!! I start college on 23! Have to have it going! Anyone have any ideas!? Asap please!

 

Well something definantly not hooked up, no spark either I don't believe. Every like 5th time I crank it, it makes a slight start noise with starting fluid. But never any other time. So no constant spark. I guests I'm over my head. Might just sit untill I can afford a shop to hook it up for me.

 

Could it be the cam or crankshaft sensors? I will replace them if it's the problem. Any way to check for sure? They show voltage

 

Ok I got it running only with starting fluid. But fires everytime with it. So its fuel for sure! I'm getting fuel to the injector tower, they are just not getting signal I don't believe. Any help!? Please!? So close! Sounds so good for those few seconds!

 

I'm gonna say your not getting help because u dove into this head first apparently without doing nearly enough research. These guys have been overly generous so far as in supporting you and knowing this fact already. It sounds like your almost there after a few bugs are worked out but I think you already stated your problem. You got in over your head.

 

I'm replacing the crank sensor tomorrow. My wiring is fine. I re-checked too Many times. It's a sensor or something under the hood at this point.

 

It's your wiring. Forget the sensors

 

I like you.

 

Should I really not bother with the sensors? Injectors not giving pulse, crank sensor is what sends it. I don't see any other way of wiring it.just the injectors not sending fuel.obviously getting spark.

 

Are you sure you don't have the fuel lines reversed?

 

I have the line on the passenger side getting the fuel. If I hot wire the pump I can feel fuel going straight through the return line. No pressure possibly?

 

my bet is the power to the injectors is wired incorrectly

 

Ok ill check again but can almost swear its wired in right. Red white b+ and constant, and ign2 all power

 

There is no red/white wire that supplies power on a 3.4 that i have seen but I havent seen everything. Maybe this one is different than the ones that I have worked on. I have only been into the 97 models.

Honestly, I never thought that you would get this far based on the questions that you were asking, but I will admit that I was wrong. Keep at it and when you find it, you'll be amazed it was right under your nose and you looked at it 25 times.

Id say its a wiring issue as well. If it was me I would ohm out ALL OF THE WIRES again. CPS rarely go out but they do I guess. Do you know someone that you could swap with? Did you test it? Very eqasy to do:

INSPECTION
NOTICE:
”Cold” and ”Hot” in these sentences express the temperature
of the sensors themselves. ”Cold” is from −10°C
(14°F) to 50°C (122°F) and ”Hot is from 50°C (122°F) to
100°C (212°F).
INSPECT CRANKSHAFT POSITION SENSOR RESISTANCE
Using an ohmmeter, measure the resistance between terminals.
Resistance:
Cold: 1,630 − 2,740 Ω
Hot: 2,065 − 3,225 Ω
If the resistance is not as specified, replace the crankshaft position
sensor.

 

Ok well thanks, been working on it constantly and trying to figure it out since last post. The crankshaft sensor is fine.

 

Is the data link connect

 

Is the data link connecter 3 the actually OBDII port? I am going to try and hook that up and see what codes I get.
