PharmPath Posted April 5, 2015 Share Posted April 5, 2015 My 95 Pathfinders seems to be running on only 1 bank of cylinders. Runs very rough. I'm getting spark to all plugs. If I pull the ignition wires from cylinders 1,3,5 - it has no effect. The engine appears to be running on cylinders 2,4,6. Any idea what this could be? Thanks.

bushnut Posted April 5, 2015 Share Posted April 5, 2015 did this happen suddenly? have you done a compression test? is there fuel going to 1,3,5? more info please. Link to comment Share on other sites More sharing options...
PharmPath Posted April 5, 2015 Author Share Posted April 5, 2015 Hi. Thanks for your help. This did happen suddenly, after I replaced the fuel pump. Haven't done a compression check. Link to comment Share on other sites More sharing options...
bushnut Posted April 5, 2015 Share Posted April 5, 2015 so this should be related to fuel then. could be you stirred up some sediment when installing the new pump. maybe clogged injectors and or lines? have you checked fuel pressure? I'd investigate this before throwing any money at it. Link to comment Share on other sites More sharing options...
Precise1 Posted April 5, 2015 Share Posted April 5, 2015 Pull the plugs on that side and see if they are getting gas. Quick, cheap and easy... The fuel rails have connecting lines so I'm not sure how only one side would be blocked, but it would be one thing to verify/rule out. Other possibility would be if the timing belt jumped teeth on that cam sprocket so that bank is out of time. When was the last time the timing belt was changed?
