OK can any one tell me where to go from here!!?? ..

I've got an RB20det in my s13 silvia, and the bloody thing wont fire on cyl NO.6..

I've swapped spark plugs, coil-packs and ignition loom, but no luck..

I dont think its the injector coz i can smell fuel in the xzorst when the car is at idle ..

Now i'm thinkin the next logical step would be crank angle sensor ?? or dare i say it, ECU? .. considering it cost me over 2k for some half-wit at a repco service center to wire up the stock ecu i'll be less than impressed if i have to throw it in the bin.. (dont even think about tellin me i payed too much for the wiring job, I'm only too aware that i got f*kt over..)

So where to from here guys?

i would very much like to stop waistin money on my piece-o-sh*t silvia and have a functional vehilce again ..

I'v asked in the maintenance section but got a grand total of zero (0) responses so any feed back would be just dandy ...

peace

have you tried stock ecu diag?

[Bl4cK32]

have you checked the coil pack loom? Make sure there is spark getting to the coil?

Just a thought....

edit/ i see you did the ignition loom Id keep tracing wiring. Go all the way back to the ecu etc.

Have you changed the ignitor box yet?

The transistor for #6 is probally cactus...

its quite simple really....take out the one thats giving you the trouble....earth the spark plug out and crank the engine to see if it sparks......if it dont jam a screw driver in the end and place it about 5mm away from an earth and crank it....if there is no spark then change the coil with a known good one then test it again......if it still dont spark check the wiring if its all good then swap one of the pins from the ecu to the module(eg number 3...a known good signal) in to the no 6 one then check it....if no spark then the module has died.....if it does then your ecu is dead

OK i'm gettin spark.. earthed the plug and got a spark.

pulled out the injectors this arv to get em tested .. interested to see what sort of condition there in ..

thay all look pretty crappy but the suspected faulty injector appears to be in better condition then the other 5?.. i know looks can be deceptive so i'll have em all tested ..

thanx for all the feed back ..

i'll keep ya posted

Being an RB20 the chances are the injector boots are cracked.

Check out the connection, it may be corroded causing little or no connection. I had this issue with injector no. 3.

Coventry's/Motor traders have bosch plugs for ~$16 each OR you can buy another brand that come in a 2pack for $16, I went the cheaper route and replaced all for ~$50.

It may sound silly but do you have compression on that cil.?

[T04GTR]

could be an injector. seen it before

pull the sparkplug out and smell if its all fuely :lol:
