1993 Grand cherokee won't start

[Mira_cz]

Hi, I have 1993 Grand Cherokee. It won't start. Fault codes show: FLASH, FLASH, FLASH, pause, FLASH, FLASH, FLASH, FLASH, FLASH pause, FLASH, FLASH, FLASH, FLASH, FLASH - I think it means 3, 55. But I don't understand it. Have you got any Idea please?

And second: what matters if you remove car battery for a longer time and then you return it back? Is there some special mode?

Thank you. Mira

Hi Mira,

Try again on the codes - they should be 2-digit numbers.

55 = end of display (normal)

Take Care,

No, unfortunatelly Friend with jeep adviced me to go to official chrysler service. He told it is something wrong with computer.

Have you checked for SPARK at the plugs, cap and coil, while cranking engine? Have you checked to see if you have fuel pressure?
