1G 1g wont start. no spark

[jonnyox]

4g63 non turbo. getting no spark. new ignition coil, new spark plugs. car cranked fine then when i was backing out of my driveway the car just completely turned off. i’ve researched a little and found either the CAS or ECU. ECU looks fine besides some dried white liquid. could there be anything else causing this?

I'd stop throwing random parts at it and diagnose the problem.

How To Diagnose A No-Start

Diagnosing a No-StartI've been seeing a lot of No-Start related threads popping up lately, and I figured a basic Tech Article for diagnosing a few of the most common No-Start problems might be in order. Any images posted are courtesy of my 1990 GSX your setup may differ slightly; refer to...

Have you ruled obvious mechanical issues? Broken timing belt? Does tach twitch while cranking?

yes i’m 100% sure there’s no spark. i can smell gas when i try to crank so fuel is there. i haven’t noticed the tach twitching, but i haven’t really been looking for that.

Can't remember differences between years but on my 90 when ignition transistor failed tach didn't move. No spark. Car cooled down it started again until transistor got hot again

care to provide more detail or pictures on this? Is it on the ECU board somewhere?

Be prepared for bent valves and possible valves guides. Look for another head just as a backup.

I just fired my motor up for the first time in 3 years and I have BC 272's. I forgot how choppy and angry those things sound at idle.
