Ok so I was driving for about ten minutes and when I pulled into parking lot, my cherokee died. I started it back up and when I let off gas and pulled into parking spot it died again. this time. I left it alone for a minute, then tried to turn it back on. WOULDN'T TURN OVER. soo I tried turning it on again and hit the gas when I did so, it then turned on and made it home. (5 minute drive) WHAT COULD THIS BE??

I already checked battery, and alternator. Both are good. Please help

 

Well, till somebody else comes along....When it's dead you could check for spark. Also you could push in the little tire type valve (Schrader), on the fuel rail and see if fuel spurts out. (Catch it with a rag. You don't want it running down towards the manifold). Also when it's dead, do you hear the pump run a second when you turn the key on? Also when it's dead if it fires with Starting fluid you can figure it's a fuel problem. Have the gauges been goofy? Got a check engine light? You could try this;

1984-1990 w/AMC engine are pre-OBD.

1984-1986 w/GM V6-173 are OBD-I (GM control setup.)

1991-1995 are OBD-I (Chrysler)

1996-2001 are OBD-II (Chrysler)

The "Key Tricks"
Older (OBDI) models - Start with the ignition off. Within five seconds, switch the key on, off, on, off, on. ("On" is NOT "Start" and "Off" is NOT "Lock"). The "check engine" light will flash. Count the flashes. Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause). It will never flash more than 9 times, so watch for those pauses!

Newer (OBDII) models - Put the key into the ignition, push down the odometer reset button, then turn the key to RUN with your finger on the button - and then release the button. The odometer will go through 1111111 through 999999, then display the car's serial number. It will then show the error codes (it might show them starting with P). If this method does not work, try the OBDI method.

 

The newer XJs my 99 doesnt show the codes with the key on trick ive tried

 

if your 99 xj wont work, then Im sure my 93 wont pull it up either
