Re: extensive cranking on strart up 2005 Grand Cherokee 4.7l
Hi all, this site is awesome, so much good info, you guys are great!!!... Well I changed out the fuel pump/regulator and at times it still turns over to much before firing... Im now thinking bad injector...If I let it sit for 20 min or so, then try to start it, thats when it cranks the most... If I let it sit overnight it fires up perfect almost every time due to the fact the fuel has dissipated in the cylinder over the many hrs.? If I turn it off then start it right away it fires perfect. That bein said, Im going to change the injectors... What do you guys think, should I find the bad injector/injectors and just change them, or should I change all 8? I have heard from some mechanics to change only the bad ones, and from others heard to change them all. My JGC Rocky Mountain Edition has 220 000km/138000 miles on her.
Thanx Guys/Gals... Jeff..
