realtime in...but car won't start

budsang1 · 07-19-2007, 10:33 PM

I just got my realtime from calum today...I followed the start up guide and installed the bin he had emailed me...it was a copy of my jwt ecu. I wrote the bin to the ecu, it said successful, i verified it, successful again. Now, i figure, that was easy, went and put the ecu in the car, but it won't start.

the engine cranks and cranks, but won't actually start. Not sure what to do from here...this is all very new to me.

any help out there?

sounds like the bin isnt on the ecu. when its blank it will just crank.

try reuploading the rom again. start over.... seriously.... just try rewriting it, wont hurt. but just clear it and reupload

Do the radiator fans run as soon as you turn the key to the ON position? That's another sign that the program isn't loading into the ECU.

is there a certain way to clear it? Or do i just write over it? Can i do it while the ecu is connected to the car? I do i need to remove it again?

budsang1 · 07-20-2007, 07:44 PM

i just went through the startup guide again...same results, just cranks and cranks

Are you sure the ECU harness is fully seated? Have you tried physically uninstalling then reinstalling?

Bowlcut · 07-20-2007, 08:35 PM

id remove ecu and reinstall to make sure everything is fully seated...doesnt hurt. do you have another ecu to verify in the car? or maybe...the clutch switch isnt getting closed...just throwing out ideas

budsang1 · 07-20-2007, 09:22 PM

removed ecu, went through startup...again. reinstalled ecu, made sure it was extra tight and seated....same issue

chriscar · 07-20-2007, 09:25 PM

So do the radiator fans run as soon as you turn the key?

no, key on the on position, everything seems normal...when i try to start it, it just cranks and cranks

Hey Chad, I'll e-mail you a different bin in the morning or late tonight. Try this, turn the key to the on position (where the fuel pump comes on), then check and see if you can get a working consult connection (use conZult freeware, etc). If yes, see what codes the ecu is throwing.

my nissan data scan program connects when the key is in the on position.

when i click self diagnostics is says code 55: No Faults

You sure the fuel pump is coming on? Make sure you are getting fuel. also check spark? Sorry I am not familiar with how much experience you have, just saying, you sure it is not anything else? And of coarse, don't do what I did and plug the o2 sensor into the igniter plug

Good Luck

i can hear the fuel pump come on...i'll check my plugs...It was just running fine prior to putting the ecu in.

chriscar · 07-21-2007, 09:57 AM

Did you change anything else, or just swap out the ecu? Do you have another ecu to test with?

no...everything remained the same...The only thing i did change was the battery, but i started it after i put in the smaller battery when i had my other ecu. It then sat for 2-3 weeks while i was waiting on the realtime...during that time i also sold my old jwt, so i don't have an ecu to test it with

Does it sound like it has power??? fuel pump prime nice?? When i had no program on the ecu it started but died right away like it had a maf issue...but nothing like your describing.

maybe try stock rom to see if it starts?

budsang1 · 07-21-2007, 12:11 PM

i'm running 370's @ 3bar and a z32 maf...so it's not going to run with a stock rom either right? Calum sent me the 370's w/ z32 maf at 3 bar and 4 bar. I've tried both and I get the exact same result. I just changed my plugs with some fresh ngk bkr7's and again, same exact results

U12BBDreamer06 · 07-21-2007, 12:24 PM

i was just saying if you can get it stared on the stock rom not run it...maybe a problem with the rom.

MyRedS14 · 07-21-2007, 12:41 PM

I'm going to say you have a dead or weak battery. Have you tried that? I know you switched it out, but it did sit for 3 weeks, right?

I'm in NO way trying to insult you or your knowledge, just running through possibilities...
