My 2000 Jeep grand Cherokee 4.7L, V8 for mistake had a small short circuit between the (+) generator cable and (-) generator body but the ignition key was off. Now wont start only crank. Should be As a consequence the engine does not work, Each electrical components may have been damaged? Can be the PCM? Junior

You buy an ignition lock and two keys, you fit is and then get a mobile locksmith to reset the security system and immobilizer.

probable a bad engine control computer if there is no code. could also be bad crankshaft positioning sensor, or camshaft positioning sensor.

starter relay sounds like to me. or bad ignition switch but im leaning twards the relay, sounds burnt out to me.

Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

POSSIBLE CAUSES

• Powertrain control module
• 5 volt supply circuit open
• Check transmission fluid level and condition
• GOV press sensor signal circuit shorted to voltage
• GOV press sensor signal circuit shorted to sensor ground
• GOV press sensor signal circuit shorted to ground
• GOV pressure sensor signal circuit open
• Sensor ground circuit open
• GOV press sensor signal circuit shorted to voltage inside transmission
• 5 volt supply circuit open inside transmission
• Intermittent governor pressure solenoid
• Internal transmission problem
• Oil burnt or oil pan has excessive debris
• Other transmission DTC'S
• GOV press sensor signal circuit shorted to sensor ground inside transmission
• Valve body
• GOV press sensor signal circuit shorted to ground inside transmission
• GOV press sensor signal circuit open inside transmission
• GOV press sensor ground circuit open inside transmission
• Governor pressure sensor (high)

Wide tires make less gas millage, get narrow wheels, let the car accomplish speed slowly from 0 to 30, look at air filter,if shortly replaced, oxygen censor, 15 miles is normal 16 miles per gallon is good for a V8

on a 2000 jeep grand cherokee the violet wire with a black tracer is the power for the backup lamp ...the black is ground

insufficient info. The cruise control has a cable that runs from the servo, located just in front of the battery, to just behind the air intake, to the throttle body. (This is on the 4.7L V8 engine.) Check for that cable being connected at the throttle body. That connect is adjacent to the accelerator cable.
