i have a 1985 4 runner that i put a 97 3.4 v6 into. when i first tried to start it we didnt have any spark at the plugs. i installed the obd2 plug and before i could plug it in we noticed spark came back. the truck fired right up and i drove it a couple weeks. i tried to run the obd2 codes but had 2 different scanners tell me it couldnt communicate with my vehicle. drove it any way and it ran good. none of the gauges worked to good so i installed some 2 inch euuus. the oil was mechanical and i had to remove the oil sensor to install the port. the temp i installed the sender under the plenium against the fire wall. i removed the 1 wire plug and installed the equus sender running my own wire. i put the battery one where it used to be in the wiring harness . as for the rpm come to find out i shouldnt have put it in its usual spot on the 22re harness. guess itll ground the system. found that out after it woudnt start and thought if i unhooked it the truck would fire up. didnt work...

like always it wouldnt fire up. when i fix ˟˟˟˟ i fix ˟˟˟˟ good lol. started checken and found out the phantom problem came back. i got 12 v to the coil packs but no spark at the plugs. turns over fine and dont even try and fire. i went to the store and spent 100 bucks on a obd2 scanner. weird thing is, i didnt change anything and now all the sudden the scanner is reading.i have 4 codes, one for temp censer 1 for oil censer, mass airflow and tps i believe. thing ran great before i installed the gauges. all fuses and grounds seem fine. im more of a fabricator than a mechanic. thanks for any ideas, im about over this project ps... the engine harness was done by a company in north carilina called tweeked performance. it ran great for 2 weeks so i assume they did a great job. im new to all this ecu ˟˟˟˟.

one more thing. all of my fuses and such are all the old 22re stuff. thought that might be usfull info. HELP ME HELP MYSELF! if i dont get this thing figured out by thursday i may take it to my auto eletric buddy. id rather not have too.

 

Myself I would start reading all the threads in the 3.4 swap section.

Someplace you have a poor connection .

Perhaps even poor grounds.

OBD II plugs can corrode getting the unable to connect message is quite common when I try and pull codes .

Sometimes just unplugging and reconnecting is enough. Other times Electronic cleaner is needed

 

Wow -that 3.4 sounds good. I want one!

 

thats without the magnaflow hooked up but thanks. your right it DID sound good.

 

broke down and took it to the local auto eletric guy. ill let you know what i find out. . i hope he finds it fast lol

 

Because this is a swap there will be no fast in trouble shooting .

I hope the company that did the harness sent a schematic showing just what was done.

Best of luck.

 

Wow that sucks. All my gauges in my cluster worked after my swap.

 

Waiting for an update
