Engine Performance problem
2000 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 131000 miles
Hi all, I can't really fined anyone thats had quite the same problem as me so I thought I would ask you guys. I have a 2000 XJ with 130,000 on it, I bought it about 3 weeks ago and ever since I bought it its been hard to start. It takes about 6 seconds of cranking to get it to start and then it runs and drives fine. After I start it once it strats right up, then after about 20min or more of sitting I have to crank it for another 6 seconds or so to get it started again. I dont think its the battery because the starter turns good through the 6 seconds of cranking everytime. Also pushing the gas pedal down has no effect on starting it and turning the key on and off a few times doesn't work either.
Here's what ive done so for to try and fix it:
Replaced fuel pump and check valve (has good presure)
Replaced spark plugs
Replaced Coolant temp sensor
Had CPS checked and is fine.
There aren't any error codes either.
I think its a ignition problem because it has good fuel presure. I srayed some starter fluid in the air intake to see if it would sart faster and it didnt so i'm guessing there's no spark for the first few seconds of cranking.
Any help would be great thanks!
