Our Grand Cherokee was running fine three days ago. Yesterday it would not start, will not even crank over. Battery tested good. I looked at some of the fuses, didn't find any blown. Any ideas?

You need to check all the important fuses, the starter relay, the ignition switch, the neutral safety switch, wiring and starter itself, as well as block ground etc. Any shop you would take it to will need to test these items one by one till the problem is identified, using a volt meter or test light.Good parts and bad parts look the same 'till they are tested...though it would be nice if they turned purple or something when they fail, they don't.
If you want to fix it, start at the battery and work your way through the system 'till you find where voltage goes in but does not come out. That part is failed.
Shops don't guess...you shouldn't either.
good luck.
If you need help with testing a particular item, ask.

2003 Grand Jeep Cherokee will not start.


Could be a faulty starter or bad connection between the battery and starter. You could use a meter to check for voltage at the starter but it will not show resistance in the cables.

1995 Jeep Grand Cherokee Sport it just won't start. It cranks, that's it. It was running fine yesterday.


If it was running yesterday and only cranks this morning you need to determine which you are missing - spark or fuel. The spark is easy - pull a plug and let it spark to the frame. while cranking. If you have spark then you have to start checking the fuel system.

87 f250 drained brand new battery


I would first have the alternator checked by an auto electrician to ensure it is working correctly and is providing the correct volume of current. It may be faulty and when driving you will be drawing battery power instead of power from the alternator to run the electrics. This will drain the battery.

Alternators do not last forever and if you are still running the original unit it is likely to be on it's last legs and you will need a replacement unit.

My 2004 Jeep Grand Cherokee started perfectly yesterday morning. After stopping, turning off the car for about 5 minutes it would not start. I had it towed to a repair shop, where it started and all tests...


A definition: cranking is what happens when you turn the key, the starter engages and turns the engine. (term comes from when that was done with a crank that you stuck into the front of the engine to start it, before electric starters were invented) Turning over is the same as cranking. Starting is when the engine actually starts, even if for a brief moment.
Now...if the engine turns when you turn the key it is cranking. Was it doing that? If not, the problem is either in the battery, starter/starter relay or security system (sometimes) or the ignition switch. If it is turning and not starting, then the engine needs to be checked to make sure it has spark at the plugs, and fuel going into it. These problems are different ans some can be easily solved.

1993 Jeep Grand Cherokee engine problems


First run a code check, see what you find. Second, you can do individual component testing with a decent volt/ohmeter to pinpoint problem. (instructions for tests in any decent manual)
Just off-hand, most common failure with similar symptoms to yours is crank position sensor.

1997 Jeep Grand Cherokee cranks but won't start


Same thing happened to me at about 140k. It was the fuel pump. Best way to test if your pump is failing and loosing pressure is to see if the car will start immediately after it has been running, or turn the key to the alt position for a few minutes before starting. If your engine fires faster after it has been running or the key has been in the alt position you will probably need a new fuel pump. Great news is with a very deep socket to get the tank straps off its a 30 minute job to replace the pump/filter assembly.
