Only two injectors getting power????

[cruisintalonawd]

What would cause this problem. I searched but other people were have no power to all 4 not just 2 of 4

That is what the resistor box is for ^

Did'nt realy read the thread, but Did you test the power transitor
most of the dsm's I've seen not firing on 2 cyclinders that was the problem

Dont Forget The Turbo And Non Turbo Ecu's Are Not The Same. Even If The Ecu Worked Great In Your Buddies N/t It May Not Drive Your Turbo Injectors. Different Resistance Between The Turbo And Non-turbo Injectors. I Had Same Problem A Few Years Ago And A New Ecu Did Me Fine.

I was told that I could start it up and rev it but it wasn't a good idea to drive and boost with it since the fuel trims are different I'll find that thread.

Isn't that to do with spark....I know I'm getting spark..Also i tried two different ones

yes, the power transistor is a switched power relay for the ignition system and the tach. but it does not run the injector power.

I tried this and I got nothing. Does any one know how to test the wires

Ok so it's not late and I read the thread now...

Did you check for continuity? or test the Ohms ? of the wires,you should be doing the first

You sould be pulling the ecu and testing the pins of the wiring harness to the injector clips for continuity... to rule out a break in the wiring

Have you opened the case of YOUR ecu to look for damage?
Also why are you trying to start the car with a N/T ecu?

Yes it appeared normal looking. And i was trying the NT ecu just to see if I missed a bad spot on my turbo ECU

 

[cruisintalonawd]

I tried checking the resistance on the wires from the ecu pin to the injector clips and it is acting like the wires aren't connected at all(any 4)


For EPA nightmare; I checked the battery voltage and its 12.23

 

[MY1GDSM]

Your not checking the resistance,... your suppose to be checking for continuity

 

[cruisintalonawd]

My bad My dad said I did that...But um if it not getting any continuity why would I see some voltage the the connector?

 

[cruisintalonawd]

I just had the battery short on the hood so I guess I'm going to look for a new wiring harness

What burned up on the harness?

 

[cruisintalonawd]

the ground that is in about the middle of the firewall. Has about 3 or 4 wires. That whole piece of that loom is melted together. If I can get this other talon in town for cheap enough I will just scape the car I think, unless I can get a new wiring harness for a good deal
