1998 Jeep Cherokee - won't start when raining

I have a 98 jeep cherokee I just bought from my brother with 175,000 miles on it when purchased. He is a car person and, as far as I know, maintained it well. Problem is that, despite installing a new battery a mmonth ago, whenever it rains the car won’t start, turn over, etc. How might I start figuring out what is wrong?

Wet weather starting problems are usually just ignition related. They usually mean a need for a good tuneup including spark plug wires. Occasionally they’ll mean a cracked coil housing ir whatever. I’m assuming the engine turns over by doesn’t fire, which is the usual wet weather malfunction.

Start by doing a thorough tuneup. If that doesn’t fix it post back and we’ll suggest some further testing of the ignitoin system.

Coil packs absorbing moisture?


#4

When the weather is dry, spray the spark plug wires, ignition coils, ignition whatever, with silicone spray. It could seal out moisture. If it doesn’t work, go to plan B.

[b]The next time this happens, try shifting the transmission into neutral, and then try starting the engine. If the engine starts, moisture is effecting the park/neutral safety switch.

Battery terminals need cleaning/replacing. The rain may be dripping onto the battery too.

Need a little bit of information. When you turn the key,
do the lights on the dash light up, does the radio work, to the headlights come on? greg
