Geek Posted February 27, 2022 Share Posted February 27, 2022 Just a guess but don't the 4 cylinders have a CPS like the 4.0? Link to comment Share on other sites More sharing options...
eaglescout526 Posted February 27, 2022 Share Posted February 27, 2022 As above check to see if the CPS is plugged in. That tells the ECU when to allow the ICM to send spark to get that engine going. The CPS is located on the drivers side of the transmission bell house. Link to comment Share on other sites More sharing options...
gogmorgo Posted February 27, 2022 Share Posted February 27, 2022 Yup. Crank position sensor would be super easy to miss if you weren’t the one unplugging everything. It’s also pretty exposed and possible to damage during engine removal and installation, as it sits as close as you can get to the flywheel. Also make sure all your grounds are hooked up. Cruiser54.com has a good reference to where they’re all at. Link to comment Share on other sites More sharing options...
