Default No Spark.

Sitting at a fast food drive through and she just went dead, like I turned off the key dead.
Turns over fast but will not fire. Had to push it to a parking space then have it towed home the next day...it was late.
No garages local could take it this week.
Check engine light never came on.
It has plenty of fuel.

Tomorrow is going to be the first chance I have had to really look at it.
For now I know I know nothing about this engine. I gave up on repairing engines in the 80's. Give me a small block and a carb and I can make it run...add todays computers etc I am lost. However I am always ready to give it a good try before paying someone else.
That was a brief introduction..my first post here. Hello all

What I have found thus far in my 1 hour of before dark, after work, is:
I seem to have no spark. Grounded spark plug will not spark...engine spinning. Fluke meter on DC detects nothing at the coil or the spark plug wire. Replaced the cap and rotor today....never hurts....did not help.
Fuel pump runs.
Check timing tomorrow...but even if the belt or chain jumped it should produce a spark....right????

I simply need some advice on where to start looking or if there is a common issue. I seached this thread 12 pages
All fuses check good.
Any help is greatly appreciated.

Not sure how to navigate this place. I hope I get this right. My dodge 1500 did the same thing but in my driveway. 10 days ago and hasn't run since. If you could help me spread the word. Brand new HEI Distributers for mopar. $58.99 eBay or autopartszone2008. Bypass the computer and security that isn’t sending any codes, everything is reading good but security is not going to work right. No proof but don’t it seem strange all these dependable trucks just hiccup and completely stop like an internal clock for self destruct went off. Get one of those distributors while the price is down if you don’t wanna spend better than a grand.

Broke this out into a new thread for you. Posting in a 15 year old thread really isn't a good idea......

First, what are you driving? Given your symptoms, I would suspect your crank sensor just died.

I would check the crank sensor. SOMETIMES if the motor is dead cold it will work. If you decide to replace it I would buy a Mopar unit

X2 on the crank sensor, Computer needs inputs from both crank and cam sensors before it will fire the coil.
