On most multimeters there is a conductivity test. Usually it beeps when something is conductive. You can test the diode by probing both ends with the multimeter and it will beep one way and not the other and that way you know the anode and cathode.

Ban what did u guys used for Injector Settings?

You do mean me, right? ;)

Uhh, I'll grab Dan's Injector Settings tonight when we run his car against my brother's Sentra SE-R (yes he as the same car I do) for benchmarking purposes.

[BenFenner]

The specs are up in Dan's thread.

Yes i mean you BEn :)
Thank you guys you are awesome! :)

I`ll try to start the car tonight....

[gox]

I tryed to start the car but no sucess!

It comes up on few cylinder (2-3) and its cranking that way,doesnt come up with all six,i tryed lowering req_fuel - notting,i was playing with Priming,Cranking and Afterstart there are some changes but anyways it only cranks and starts on few cylinders,it is not idling on few cylinder its just cranking and i can hear few cyls fires up but notting...

I used Bens Priming,Cranking and Afterstart settings i was increasing and decrasing values but notting,always the same,i put out spark on cyl1 and it was little wet,so i`m flooded,i got Pulse Width gauge in MT on 3ms
if set it to 0ms there is no fuel.

What would you sugest to try changeing to try to get it running?
Engine havent run in month or two...
What values are connected with starting?

I hate stupid problems,there is fuel,there is spark and its not working....awwww

I will post my config and tables

Sounds like things are getting wet on cranking or afterstart.

Take thing back to the beginning.  Pull your plugs out to let the engine dry out, and give the plugs a clean.
Take the fuel pump fuse or injector supply fuse (or both) out, and spin the engine over to get all the fuel out of the bores.

Put the plugs back in, and check that you are getting a spark on each cylinder.

In the Settings->Priming Cranking and After Start:
Set the priming pulse to 0
Set the cranking threshold to 3000 - you'll set it back to 300 later, but this is a way of forcing the pulsewidth and will give you an idea of what PW you're looking for for starting and idling.
Set both Cranking PWs to your Req Fuel amount, and try starting the car, if it back fires out the inlet then you're probably lean, so add more to the cold cranking value to increase the overall amount.

How are your inejctors connected: Are you firing sequentially, or batch?

Ok,i`ll try everything tomorrow.

I`m firing injectors 5..0,sequentially and it is set to fira All Banks while cranking i will switch that to Alternate

Update:

Car started up two days ago and i did some tuning last night and got it running realy nice,there are some more spots that needs tuning,mostly on higher rpm load.
I will post my maps later.

:)

Tnx everyone who helped me!

[BenFenner]

Congratulations. =]

[danmartin]

sweet, it feels good doesn't it?

[gox]

The car is now running very nice,it need more tuning at high rpms and loads.Its running much better then on motronic and i found out that these injectors are small,as i have seen 101% duty cycle :( I will install 19lb's ones as soon as possible...

:)

It feels great :)
Still dont have idle control...  :-\

[[email protected]]

What happens if you set the idle control to on/off type?

[gox]

Well i dont have idle valve at all...didnt tryed to set that stock stepper valve,but i will.
Cold starts are problems,when warm its starts excellent...

How do i tune Warmup? I think thats the problem....
