Question about 1998 Plymouth Neon
Plymouth neon 1998. no spark according to timing light....but when checked with wire and clips the coil pack is producing spark on clip. It might be moisture down in spark plugs...havent checked yet. I think crank and cam position sensors are working, because there is a spark from the coil pack...also i read that a way to detect crank p.s. or cam p.s. are not working is that it will shut off fuel pump after a couple seconds. Tried cranking engine for five seconds and no fuel stop. what in the heck else could it be. Also, strangley, the gas pedal seems loose or weak when i push it with my foot (i dont know if there is any correlation). Checked to make sure gas pedal was opening valve for air, it was working fine. Battery checked also, still pretty good. Tried also starter fluid in air intake...nothing. It's like there is absolutely no spark....although, by all means there should be. What in the hay??? Any help would be appreciated. thank you April
I dont know too much about cars, but since I own the same model, I thought I would shed some light on the situation.
All Chrysler vehicles came with service codes. Meaning, it will give you a number and you can go look up the problem. I am just going to insert the way I found out how to do it to check my car.
Turn the ignition ON-OFF-ON-OFF and ON (not start) within 5 seconds. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. FLASH, FLASH, FLASH, pause, FLASH, FLASH = code 32.
A code of "55" represents end of error codes. If you only get this code, then no error codes are stored in the computer.
Post the numbers you are getting and I will glady tell you what your codes mean.

The valve cover seals like to leak and fill up the spark plug tubes with oil. so 1st thing, you should pull the spark plug boots to check, the pull and inspect the spark plugs.
pull spark plug boot off of the #1 spark plug. Insert a new spark plug into the spark plug boot. Ground the plug to the engine.
Crank the engine and look for spark across the electrodes of the spark plug.
then reconnect the boot the the #1 plug, pull the boot off of the #2 plug repeat the test, then do #3 and #4.
if all cylinders have no spark/ weak spark, its most likely a bad coil pack.
to check the coil pack:
Measure the primary resistance of each coil. At the coil, connect an ohmmeter between the B+ pin and the pin corresponding to the cylinders in question. Resistance should be 0.45 - 0.65 ohm.
Measure the secondary resistance of the coil between the towers of each individual coil. Secondary resistancokay, thanks for reply earlier...here's more info. - 55ffb2d.png
11k - 14k ohms
