92 won`t fire

I HAVE A 92 LX 4CYL I BOUGHT FOR MY GRANDSON RAN OKAY FOR AWHILE. NOW IT WON`T START CHANGED PLUGS,COIL PACKS (HAS 8 PLUGS) AND ENGINE CONTROL MODULE. STILL ONLY GETTING YELLOW SPARK AT PLUGS ANY IDEAS OR SUGGESTIONS. E-MAIL gus1382000@yahoo.com THANKS

Any applicable trouble codes? There is a dis module and engine control module, not sure which you replaced? At the coil pack, red wire with lite green tracer, use a digital multi meter, what is the actual voltage reading? Make sure the battery has a full charge.

No trouble codes check engine light doesn`t come on . Changed the engine control module.
