My wife was driving my cherokee and she said the pedal went dead. She pulled over turned it off then it would not start. I am not in town to look at it but I am just trying to get some ideas of what it could be. Any help would be awesome. Thanks

If its the same as the 2000 I would start with the crank shaft position.

Start by seeing if the lead wires at the plug (under the car) are receiving 5 volts dc. With the key on.

I bough one off of ebay For 8 buck to replace mine to see it it was the problem.
It was so now I'm going to by a better one

It's an easy fix

Good luck

I am afraid I need a bit more info to even start to guess. Define "pedal went dead". You mean the engine cut off? Also how exactly won't it start? You turn the key and nothing happens at all? Just dead silence? A click? Or the engine cranks and it won't start? Power to anything?

yep, a bit more background info would be helpful in this.

I am not currently in town. Just going off what she told me. The pedal went dead but the Jeep was still running. She pulled over turned off the Jeep then it would not start. The tow truck guy said fuel pump but I am assuming if that went out the Jeep would have died on the road. So my guess now is tps. But I am not 100 percent sure

Could even be a dislodged throttle cable...

So I replaced the tps and it seemed to have helped because now it sounds more like it wants to start. Just seems to be little fuel pressure at the fuel rail. Going to replace the pump now

You say it sounds like it wants to start so I'll assume the motor is cranking over. Before you do anything else check to see if you are getting spark. Did you put a code reader on it? Mine was not getting spark and the code reader said cam position sensor. A bit of research told me it was more likely the crank pos sensor. Replaced that and it started right up. Very common problem apparently.

Make sure to do the filter and even maybe the short lines at the back for some cheap insurance ($15?)

Stay away from airtex pumps.

I don't know how it could have stayed "running" if it was the fuel pump, like you said, but I mean if you were willing to do the pump I guess it won't hurt. Just sucks on the newer ones you need to drop the tank (mine went not too long ago but luckily I can get to mine at the front of the tank)

Don't replace the fuel pump before you check for spark. The best fuel pump in the world will not start it without spark.

^ agreed, check CPS, which was already one of the first replies at the top.

Fuel pump should be last, and it would be ideal to test fuel pressure first if possible anyway.

My 99 would loose throttle response suddenly. I could press gas to floor but jeep would slow to a stop but might not shut off. Sometimes it would buck forward before it happened and eventually it started cutting the jeep off. Crank position sensor was culprit.

My '94 wouldn't start either. I am not familiar with '98 if it's similar. Mine was the NSS switch. Neutral Safety Switch.
Check out the threads.

This thread is going all over the place very soon.
OP, unless you plan to replace all parts anyway that could be involved in your no-start situation, the replacing-parts-until-it-works will be an expensive way to deal with a problem.

Post #7: " Just seems to be little fuel pressure at the fuel rail. Going to replace the pump now"

Really??
How about some simple diagnostics first? A no-start is a very common issue, and the forum has dozens and dozens of threads relating to it. Some simple tests and diagnostic procedures will guide you in the right direction quickly if you'r willing to invest some (free) time and safe $$ .
