LoLifeRanger - Hey guys, got some problems

[layinranger]

hey guys. its been soo long since ive been on, i forgot my password. anyways...since ive been on, ive had some major changes.

i got my motor running perfectly in my 94, finally. got all the bags done, independant and all, drove it, and hated it.

scrapped the project, ripped the motor out, and now ive got my 2.3t shoved into my 90 ranger. now, it was running great before in my 94, and now its just pissing me offps, just so you guys dont have to look, im still using scotts wiring harness, no electric fan cuz that circut is wired backwards, ecm is la3 with big air meter, other than that, heres the problems
ive got codes 21, 22, 81, and another one i forget. anyways, bar/map out of range, tps out of range, and air management circut 2 failure. that last one really worries me.
furthur-more, my timing is weird. dizzy adjustment seems to do nothing other than basic run/not run fuction. im unable to time at idle due to roughness and sparatic revving. if i move the cam gear back, it idles high but smooth, but wont rev past about 3500rpm and doesnt build any boost. if i move it forward a tooth from tdc it wont start or it will run extremely roughly. at tdc it wont run smooth, backfires and acts oddly. when i limp it to the road, once its off idle, maybe 2000rpm or so, it runs better builds 7psi right away, but has absolutely no power. less than a stock 2.3. less than a hondamatic 1.3l.

what is circut 2, and how does it fail? ecm problem? ive got no vac to my map sensor, think thats wrong, needs vac, but its been so long that im confused with info. bar=no vac, map= vac correct? stupid sensor on the firewall is a...?

is circut 2 failure the maf meter? if so, fuk.my buddy plugged in my ecm prior to start up in my 90, but he put the ranger one in, not the turbo, and we tried to fire it... anything come to mind that might have fried when that happened?
thanks guys.

21 is ECT out of range, 22 is MAP/BARO out of range; check to be sure those devices are getting proper power and ground (as required). The MAP/BARO in the case of the turbo ECM is used to reference atmospheric pressure and should NOT be hooked to vacumn/boost. I've seen the 81 as several different things but would not immediately suspect a faulty sensor. It has crept up on me in continious memory since making upgrades and I suspect it is a result of modifications to the EGR or PCV systems or the additional air mass from the FMIC and associated plumbing.
As for your timing issue, you did take the spout connector out when setting timing right? If so check out http://www.turbotbird.com/techinfo/C...20Set%20Up.htm and double check everything.

Scott = detail zone harness? yes, that harness thought looks good isn't fantastic. They wire all the grounds into 1 ground that mounts to the intake. that is Bull$$!T. I went to the ecm connector and pulled the ground from the ECM that is supposed to go to chassis ground and cut that wire from the harness and grounded it like it should be. Also, make sure you have a GOOD GROUND from the engine to the frame and a good one from the frame to the battery. Remove all those grounds. Sand them down so there is no paint on them and reground them. Typically dealing with a common sensor ground problem it starts with the ground problem. As for the cooling fan. Reverse the pin for fan on from pin 87 to pin 87a on the relay. then the fan will be off with the engine on and on with the key off. Then, run the ground from the cooling fan back to the 2ndary fan relay circuit 87 and the other side of that circuit to ground. cut the wire going form the 2ndary fan to the ECM and rewire that too. what you want is for the cooling fan to be ungrounded when the key is off and grounded when the key is on. Then the fan will work as designed. I tried to communicate the fan wiring problems scott when i got mine done but detail zone elected to not support the product so i said it before and i'll say it again. 400 bucks and F$%^ them!

the LA3 fan circuit is designed to ground the fan relay to keep it off and unground it when it needs to be on. So with the DZ harness when you fire up the engine, the fan comes on. if it reaches the 210-212 degrees the fan shuts off. you can fix that by switching the relay to fan output from 87 to 87a as described above and then wiring the 2ndary fan to provide ground with key on. worked great in my truck.

good luck dood

wish i had a printer to take that home... my internet is down

yeah i took the spOut out, and it would barely run. im gonna fix the grounds up tomorrow, even though ive got ground to starter, ground to frame, ground to cab in 2 guage, im gonna fix up the harness and make sure the main harness ground goes to the battery. gots the pins that are grounds i should splice out? can i cheat and connect it to the battery from the same single main ground?

ive got massive 3" intercooler and piping setup and ive definatly scabbed pcv and egr systems to get on the road.... im gonna clean up some stuff tomorrow and see how it goes

thanks for the help guys... psi im sorry to hear your out of tha game... ive been gone so long ive lost touch of all ranger-related buddies.

nice to see soo many of ya still kickin.

whoot whoot turbo rangers that never run!

the more grounds the better. make sure the cab is grounded to the frame, the frame to the battery the motor to the batter. not just the starter. The one problem I had with my truck through the years was having good enough grounds. Always seemed like it was a problem. If your truck is running crappy with the spout out you have an air leak or a timing issue.

its very possible that my intake gaskets are unusable now, as ive taken them off multiple times and never replaced... ill go grab some and re-seal the top-end.

thanx for the input psi.

I've identified the code 81 as it pertains to the 2.3 turbo, it's the boost control solenoid circuit. My BCS has been replaced with a manual controller and removed, hence the code.
