April 28, 200917 yr comment_340494 ok ill start with a bit of history, its a ae 92 seca sx 4age .its got fuel power at coil but no power at dissy no spark at plugs .after any idea,s on what could be wrong .thanks in advance.rick Report
April 28, 200917 yr Author comment_340500 It could be the igniter module. [/q i have power at 2 wires at the igniter but nothing on the other 3 wires? Report
April 28, 200917 yr comment_340507 More likely the dizzy signal, its what ground out the ignitor to make it fire.. Report

April 28, 200917 yr comment_340512 continuity between the wires coming from the dizzy to the ecu.. Report
April 28, 200917 yr Author comment_340519 continuity between the wires coming from the dizzy to the ecu.. i don't want to seem like a numb nut but I'm not used to working on late model gear whats the best way to check for this Report
April 28, 200917 yr Author comment_340531 multimeter and some long wires.. ok will check this tomorrow sorry to be a pain but was told ecu was behind left hand kick panel but i pulled the kick panel off this afternoon and could not see it. Report

April 28, 200917 yr comment_340541 Much easier to just put a test light on an injector plug to test if the ecu is getting a signal. Flashing light = injectors pulsing and the ecu is getting a signal. Report

MAke sure you use an LED test light if your doing that. A normal filament globe type of test light can draw too much current and destroy your ecu. Report
April 30, 200917 yr comment_340964 I think you've been misinformed, there is no way a bulb will damage an ecu. A typical injector will draw between 1 and 4 amps depending on the engine load Power = Current x voltage So that's 12 to 48 watts of power consumption for each injector. A typical indicator bulb is rated at 5 W, so a little tiny test light bulb is going to draw under 0.5 amp. Report

Incandescent filaments draw much more on power-up than steady-state, because the filament is cold (and has less resistance, which means more current) Report
