sinkrun Posted November 17, 2012 Share Posted November 17, 2012 My 98 xj is taking twice as long to cranking as my MJ it used to fire right up in a second now its 20-25 seconds and sometimes stumbles a little. Things I just did this week, Plugs wires cap rotor air filter coolant change and 2 new bosh o2 sensors. No codes 116,000 miles 4.0 auto. Suggestions??

Comanche_Fanatic Posted November 17, 2012 Share Posted November 17, 2012 Strong crank or weak crank? Test volts from battery while cranking Link to comment Share on other sites More sharing options...
87Chief Posted November 17, 2012 Share Posted November 17, 2012 Yeah, I would check the battery/battery cables first. Link to comment Share on other sites More sharing options...

Pete M Posted November 17, 2012 Share Posted November 17, 2012 lack of fuel or lack of spark. check to see that it's actually sparking during cranking. Link to comment Share on other sites More sharing options...
