'97 Ram 5.2 Ran Fine Week Ago. Parked At Home For 1 Week And Will Not Start To Get Assistance W/scanner. The Spark Is Present And All Cylinders Show 130+ Psi Comp. Plugs Are Clean And Wet After Cranking. Fuel Is Same As Has Been Driven With. Can't Imagine What Else To Check For. Never Even Tries To Fire.
Thanks, Mike

The catalytic converter has plugged I bet.

AND HOW MIGHT DETERMINE THAT TO BE TRUE? THERE WAS NO INDICATIONS OF WEAKNESS OR POOR PERFORMANCE. BETWEEN ROCK AND HARD PLACE HERE. THANKS

Get someone to crank it over while you hold your hand over the tailpipe. See if you can feel anything come out.

DID SO AND FOUND A VERY POSITIVE EXHAUST PRESSURE. KEEP IN MIND THAT IT NEVER EVEN TRIES TO FIRE OFF. THERE IS SPARK AT EVERY PLUG AND PLUGS GET WET AFTER ENOUGH CRANKING. I WAS UNDERSTANDING, WHERE THERE IS FUEL AND SPARK, THERE'S FIRE. IF IT WOULD AS MUCH AS "SPUT", I'D BETTER UNDERSTAND. AGAIN, THANKS

It's plugged.

Drop your exhaust in front of your cat and see what happens if you crank it. If it don't do any thing, it ain't the cat. These weird ones are never easy till fixed.
