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...

Ωhm Posted 21 hours ago Share Posted 21 hours ago Having SBEC, can he do blinky codes? If so, anyone know how it's done? Link to comment Share on other sites More sharing options...
Eagle_SX4 Posted 20 hours ago Share Posted 20 hours ago This may help. I don't know if the codes are different for the 2.5 but might get you started. Link to comment Share on other sites More sharing options...
