eeesh... my 1999 Jeep Cherokee won't start

It used to turn over and start right up fine

I left it sitting for about 3 or 4 weeks

Now, all I it does is turn over but won't start up

Battery seems fine, there seems to be fuel in the fuel rail... I'm
waiting on a friend to check spark... when I spray starting fluid in
the air cleaner, the car ALMOST starts - she shudders likes she wants
to start - but No Start

hmmm... any suggestions? could it be crankshaft sensor?

kinda weird - I've owned this car since new, always starts right up...
after the 3 or so week rest of not running her, she won't start

if you left the fuel tank mostly empty you probably have a nice
load of water in there from condensation.

Yep - I checked for fault codes = none

i tested the odb device - unplugged the radiator sensor - the tester
showed P0118 - temperature switch problem - so the ODB tester is
accurate

darn - i better check the resistance in the spark plug cables, huh?

any other ideas?

And if the plug wires are at fault, most likely a continuity check
wouldn't tell you that because the more likely failure mode of a plug
wire is bad insulation allowing the high voltage to jump to a nearby
ground (possibly via some carbon tracking thru a pinhole) rather than
across the spark plug gap.

There is a widespread myth floating around that a continuity check of
plug wires will tell you if they're good or not - it may or may not,
depending on the problem (leaky insulation vs. bad conductor).

Hello,
Is it a computer chipped key ? It is possible that you need to re program the
key.
