Can someone comfirm that a bad CAS would inditcate this type of symptom? I unplugged me CTS and it made zero difference to how the car runs, I';m guessing it could have a short. This car is going to a mechanic.:banghead::banghead::banghead:
not running lean at cruise, only any more throttle then that. someone go check the yellow with green stripe wire coming from the coolant temp sensor resistance to ground. Just on ground I'm reading 550 ohms. And the other wire is 5 ohms at the battery.I'm thinking this may be the problem. The...
had both, WB showed full lean on any throttle. open loop, its all lean. every things stock now, and its still the same. logger shows stock o2 working...also in open loop does the o2 determine fuel?
Ok, Wisemen. I need to know everything that could affect the injector pulse, or its timing or both and everything that tells the ecu when to add fuel, how much, and what affects timing. I still haven't solved this problem, and I'm aggravated beyond belief.The things I know to be good are...
zero luck. I checked the relay it seems to be working normal. I wish I could figure this thing out before I pull this engine, and get the built one installed. the block is at the machine shop just waiting for that to be done. I'm about ready to just find a new body, and sell this one in case its...
I know this is a very old thread. Is there a way of testing the fuel pump relay with a meter? Is there a way to tell if its bad? My car starts and runs, but it has zero power, It builds no boost over 2-4 psi, and everything I've looked at checks good except that relay. It sounds like I hear the...
Nobody?Yesterday I got a chance, and printed out the ECU pinout, and went through EVERY WIRE on the ecu to its corresponding sensor.....All tested good............................................
yes, thats the first thing I replaced. Did so with a rebuilt eprom.I just went through every pin on the ECU to its corresponding sensor wiring on the harness, and didn't find a single bad wire or break all wiring tested perfect....is there a hair pulling out smiley?!!!...:hmm:Now how...
Right on, Thanks for your help my friend. I'm just clueless at this point. Can you do me that favor? When you get time maybe unplug the TPS,a nd measure resistance? One came back like 7 ohms the other I had tested was 479 ohms. Thats a ways from being zero. This was on the harness side...
Well I read it either works or it does not work. I also found that one of the pins reads 478ohms when testing continuity. Other then that, all the engine sensors had good checks.Could someone check the same, and see if their CAS wiring harness side reads that similar resistance? also the...
Do you know anything about MMCd? I noticed the FL 0 section has a bunch of letters in it. the other has F, B. Alternating. is that for the boost solenoid, and the Fuel solenoid?:EDIT: NM figured that one out. after a search...Oh, according to MMCd, the air flow is all outta wack. Even...
I had a 2g maf in, and went back to the stock maf, same thing. I also swapped the ECU with an EPROM. same thing. The o2 cycles normal... with any throttle it goes into open loop, (according to MMCD) the highest inj. duty cycle is like 44%( with stock it should be twice that at WOT!!)....the MAS...
NO cat straight pipe.Your talking about, like its an air flow problem? My buddy said the same. I need to unbolt the exhaust and run it just to see if it has something blocking the exhaust. I can't see what would be down in there though?...
yeah car sat out back for a good while. It remains the same.I did check the injectors, and read 2 ohms. I even changed them out for a different set. Timing is GTG.I'm telling you I parked this car, and when I started it the next time a few days later there it was.
Good deal now if I can find one local ASAP!Ok, how do I know which pin is which? There are only five pins also.OK, I went out and checked the resistor pack again. I was on the wrong wiring. this time I got 5 ohms on pin 1 and 3, and also on pins 1-2, 1-4, 1-5.....
Checked the Injector resistor pack. Got 0011 ohms, across some, and 000 on others. I believe we may have a winner! I'm looking around to get one.Wait, is it supposed to be 10K to 6.5K ohms right?
I still have never solved this problem I've changed a lot of parts, and checked a lot of things. Nothings works. I seen iun the MMCd logger I'm getting 9.9MS on injector pulses when I get on it.....I'm at a loss.
no I haven't, matter of fact. I never heard of such thing. Where is it located? I did notice on MMCd, the injector MS pulses were way up in the 7-9's when accelerating...
I've been having similar issue also similar mods. except a MAFT Gen II.Car runs fine cruising, but soon as you touch the gas, its instantly lean. and stays there for about 10 seconds.I've swapped turbo, injectors,TPS,ECUs,MAF, problem still remains. I may look at the ECU wiring next as a PP...
no, just zero power. I got a chance to get the new TPS on, the old one read infinity wt WOT. I installed the new one, along with some other stuff to button it up, and the problem still remains.I must say it felt great to drive this old car again after 8 months of it sitting out back.checked...
coil packs are BN diamond star motor OEM.fuel pump runs like a champ (walbro 190lph) holds pressure on load also.I had a friend think the TPS isn't sending signal to the ECM. I "did" have a tps code one time, thought it was a fluke because after checking it, it was plugged in after all. In...
the only way I tested the TPS was logging it in MMcd. I replaced the maf twice, bought another 2g, then I went back to the stock 1gIt sat at home for 4-5 days without being started.1: no, it would run rich if it were a boost leak after turbo, not lean. Think about it. Metered air leaking...
first thing I did was a fuel filter, its BASN (brand ass spanking new). The plumbing is tight as dicks hat band. The reason its not building boost is theres just zero power, and my guess is the ECU isn't feeding the fuel right? I haven't a clue what to try, TPS maybe?
Ok, stock 6 bolt. Used a 2g mas, 580cc, maft tuner pro, s16g, 7" FMIC, 2" pipes. Innovate LM-1 wideband. ran great. I parked it for a few days after a family vacation, and when I started it back up after it never ran right again. New ECU, mas, turbo nothing changed.I removed all of the AM...
Yeah over nighted....And that was not the problem.....:(:beatentodeath:Checked fuel pressure, changed the pump, got 12V at the pump Changed the Injectors out a wile ago. Same difference............Did I mention I got a 280 dollar ECU for nothing?I don't get it, It starts, and idles fine...
Oh I gotcha now, the only reason I circled the upper ones its because I felt that those two spots had once had something there, about that size. I was sure of it.So your saying the orange disc cap, and the two green ones are to replace the ones missing... Can this one be repaired. I read an...
Found my problem, ECU. ISC fried the ECU. There was two parts on the ECU that pop exploded off,and burnt the board. Check the pics. Might wanna check tha out.http://www.dsmtuners.com/forums/tuning-engine-management/441813-bad-ecu-lean-wb-zero-power.html
I swear it looks as if I'm missing something that goes right here...WTFCan anyoe confirm this? Do these spots look like a problem. Maybe the popped off?...Or bunt off?Does this White stuff look ad or is is it thermal paste?
It may need to be tuned but it was running fine last week, then all of a sudden, it won't even run with a load on it. Even with the MAFT removed same result.Oh, the MAFT is a GEN II, basically same as an Apexi AFC, just more options.
I'm guessing this is where I need to post. My DD 1GB has a bad problem I have zero power, almost no boost charge, and it goes lean around 5K...like massive lean falls on its face and I seen 18 on the WB... didn't do that anymore. The ECU pulls back timing to nothing. knocks like crazy. No power...
