STILL WONT FIRE AFTER REPLACING CPS

[MATT HOWARD]

WELL HERES MY PROBLEM, I HAVE A 93 ATX SHO W?125,000 MILES, AND ONE DAY DRIVING DOWN THE ROAD IT QUIT ON ME, I FOUND OUT IT WAS GETTING FUEL BUT NOT SPARKING, SO I CHANGED THE PLUGS, PLUG WIRES AND THE COIL PACK, STILL NO SPARK, SO I THEN CHANGED THE CPS SENSOR, TIMING BELT, AND WATER PUMP WHICH WAS LEAKING AND STILL NO SPARK, ANY HELP ON THIS TOPIC WOULD BE GREAT.

It's possible the the CCRM or IRCM (depending on the year) has gone bad - It supplies power to the PCM. Are you getting a CEL?? any codes??

As a courtesy to all, please do not use all CAPS. It is considered SHOUTING.

Since there is fuel pressure, the PCM should be getting power.

As for no spark possibilites: Coil pack, DIS module, CPS, wiring faults all come to mind.

the only codes i am getting are koeo 335 and 551.

Neither code will cause a "No Spark" condition.

Continue focusing on the previous list of possibilites for attention.
