No Spark or Start.
I've been dealing with the exact same issue on my 99 DOHC. Bought used about 3 months ago, been great and just turned 100K. A few weeks back girlfriend called to say I'm broken down, no start & it was working fine.
To make this quicker, in the last two weeks I've changed out the cam sensor. Still would just randomly die, no check engine? Swapped out the crank sensor. The vehicle has not randomly died, but has started to give check engine codes. At first it was just P0300, mulit random mis-fire. Changes plugs, wires & coil. Kept clearing it, and P0300 would come back after about 15min of driving. Just tonight I got a second mis-fire code, specific to cyl 4 came up, didn't jot down code. Motor runs smooth with no hesitation or hick ups.
We have fuel pressure at the rail, several turns of the key, fuel pump keeps pumping. At least it does not die while driving along at 60. Now we just have this annoying CEL code, leading us no where.
My one good mechanic friend is not into Mopar much, and defiantly not Neon, and tells me to just sell it. I do not want to, and prefer this to all corollas and civics. Ya it's my girlfriends dd, but I don't want a ricer in the drive way if I can help it.
I wish I had info to offer that will fix this, but maybe this extra info may spark (no pun intended) a reply from someone that has been thru this before.........
