car is s13 hatchback ka motor.

bought apexi turbo timer. tried to hook it up myself like always. followed this instructions online http://home.scarlet.be/broekmans.evi...bo%20timer.pdf

now the prob is my car wont start anymore it just cranks. now i checked the e-brake voltage it only shows .8v dunno why i think theres a short or grounding issue somewhere. now after all that i took all off again all the connection for the timer. still my car wont start. but my did start before all this. i have gas. batt is good. any suggestions??? thanks.

Could be that ignition power is not getting to the ECU. There are 2 wires going to the ECU: one for switched power and one for the start signal.

espa.s13 · 11-21-2009, 04:19 PM

ic.. do u know any wiring diagram or links for the ecu?? thanks.

g6civcx · 11-21-2009, 04:22 PM

You shouldn't be touching the ECU. The wires are all in the ignition harness.

espa.s13 · 11-21-2009, 04:27 PM

yea. i was hesitant of that. anyway probably i will just but the harness. but on the online write up of this guy you gotta tap on the ecu right for the o2 sensor?

g6civcx · 11-21-2009, 04:32 PM

You should not be touching the O2 sensor if you don't know what you're doing, and especially since the stock narrowband isn't very accurate.

Undo everything you did. Get an FSM and look at the ignition harness. There are 5 wires.

fsm?? i kinda know the basics. well done is done just gotta look for the solution. i already undo everything going to check again tom have no more time today.

***S14DB*** · 11-21-2009, 04:34 PM

Your problem is with the ebrake wire not reading 12v when down.

I don't like that install guide at all.

espa.s13 · 11-21-2009, 04:42 PM

i was thinking about that one too. i think it is but i dont know where to start to look for the problem with the ebrake. when i look at the cluster brake light is always on. checked brake fluid level still ok. sucks man.

***S14DB*** · 11-21-2009, 05:13 PM

I think it's grounding out somewhere. What is the condition of the switch on the ebrake?

g6civcx · 11-21-2009, 06:12 PM

How are you reading the ebrake voltage?

espa.s13 · 11-21-2009, 06:47 PM

thanks for the help ppl but i got it. car runs good now. everything is ok. the online instruction was a bit wrong. there are 2 white/gray wires one is for the crank sensor and one for the o2. so yea. thanks again.
