ENGINE - ---- - -- - 02 sensorlime green with black stripe ----------- redblack ------ -- - - whitewhite (shielded) - - -- - black

the fuel lines are going to the right spot...no leaks in intercooler hosing...etc etc..like i said...it cranks but wont start...ne help here would be MUCHO appreciated....also...i checked the ECU...its not throwing ne codes (other than 55...which means everything is A-OK)

Are you getting spark?If you are, get some quick start and spray in the intake, and try starting if it starts for a short time or gives a sign as if its about to start, your injectors are either screwed (clogged, common on these engines), or your resistor pack isn't hooked, or you have wiring problem on the injectors.

I would start with the quick start first that if you have spark on all 4 cylinders.

Good luck,PULSAR GTRRafi

remove you sparkplug , look for fuel on them.. if they are covered... remove them all and let your engine sit overnight.

the next day .. reinstall them .. and try boosting you car with another one,and try to start it ... Mine was doing the same and i was flooding it everytime. I did that and it started riight up. Be sure your battery is up to the task mine wasnt holding charge too much...

If you flooded it many time change your oil.. mine was like juice... that cleaned the engine but well its not really good hehe

Good luck .. If its dont working after that, try looking at the basic

air/fuel/spark

Good luck buddy

the red.\/blue wire you are talking about is for the spark!!! saomething hapened to me and i wasnte getting any spark, i went over my wiring and i noticed it wasnt hooked up.

follow the directions on heavythrottle.com then go to sr faq or believ.

also, there are three brown wires if i remeber correctly, they all go into eachother, that is splice them all together, itihnk thats what i did, but it would be cool if soeone could confirm this.

nah...i couldnt find the problem...stupid thing wont turn over...im having a hard time finding the proper wiring diagrams i need for the CA...i found a plug diagram...but no wiring...the CA has a ton of wires that are no where NEAR the same as the SR as far as colour goes...if i can find a stupid wiring diagram of the engine harness ill be happy...im not sure this wiring service my friend used did things right at all...i mean they didnt even wire up the lower harness correctly...i think it personally just made more of a headache
