04 cayenne s starting issues

[johnboy wilson]

HI all ,this is my first post , I need some advise on a starting issue with my cayenne s , she started running really rough, and the engine light came on the dash ,I nursed her home and tried starting her the following morning ,she started but only just, replaced the original plug coils and new spark plugs ,now she wont start ,when I checked the plugs ,cylinder 1234 were wet with petrol but 5678 were dry with no petrol residue present, what could be the problem please point me in the right direction ,many thanks

Probably one of the two injector fuses is blown, therefore one cylinderbank remains dry. These fuses usualy blown by a short, injector wiring or coils. Also the coils themselves can be shorted. The fuses are located in the fusebox left side in the engine compartment.

many thanks RFM your a star, the 20amp fuse was indeed blown, and it was cyl 5 coil plug that was the culprit, when tested it was open circuit , not bad as these were the original ones version 00, ive had her from new and not had any issues until now, anyway problem solved, thanks again,
