eaglescout526 Posted Saturday at 07:19 PM Share Posted Saturday at 07:19 PM On the bright side, it’s an HO so you can treat your symptoms like it’s a 4.0 HO. Link to comment Share on other sites More sharing options...

It's a 2.5L, I am generally not in the know but did the 2.5L get similar upgrades to the 4.0 HO in 1991? Link to comment Share on other sites More sharing options...

woodard78 Posted Monday at 06:44 PM Author Share Posted Monday at 06:44 PM Any chance it could be the crank sensor Link to comment Share on other sites More sharing options...
eaglescout526 Posted Monday at 07:46 PM Share Posted Monday at 07:46 PM Crank sensor would cause a no spark condition but will allow the engine to crank over, just not start. Link to comment Share on other sites More sharing options...
