help on sr20det

[Blaze_Cunnings]

hi, i got a sr20det s13 blacktop. Im having spark problems. I got everything wired up but cant get a spark. the engine will try to start but it just doesnt catch and run. someone please help me on. I heard it could be the ecu, ignitor or electrical problem. if you know let me know at 706 761 3311. if anyone is willing to spend a day in columbus georgia, ill pay you for your time and treat you to dinner thanks.

if u have no spark then id go straight to the whole ignition system. distributor, ignitor, things like that. also on some cars (not sure about the sr20's) if a major sensor is bad like say a cam angle sensor, crank angle sensor, somthing along thoes lines then the ecu wont send a spark signal just to save the motor. we have a car at school thats doing the same thing. i hope that helps

check the 75a alt fuse

did u wire in the orange start signal wire that' son the dash plug?

im pretty sure it might be the ignitor chip since i tested it and several things were negative unless im testing it wrong, but check back soon and thanks for the info

the ignitor is supposed to give the coil's a negative pulse, the coils are grounded via that ground strap that's on the coil pack's sub harness, and the coils are given 12 volt ignition power via the grey plug on that coil sub harness as well. if you look at the coil packs it says E + - , e would obviously be signal, - would be constant ground, and + would be 12 volt ignition power (when key is in ON position)

bump...

no spark yet...ive ruled out the following...ecu since i did a diagnostic test and it blinked., coil packs seems to run with continuity and power, power is running from the ecu to the ignitor plug in. i bought another ignitor chip and still did the same thing. i cant seem to get a spark even tested with another extra spark plug and placed it in the coil pack and near some ground. no spark. anyone please help me!!!
