Sosa Posted June 12, 2020 Report Share Posted June 12, 2020 Help!! 2010 Dodge Journey R/t with 147k miles cranks but will not start, I’ve changed the crank sensor and cam sensor still nothing. Power is getting to the coils According to the harness but there is no pulse or spark when trying to start. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted June 12, 2020 Report Share Posted June 12, 2020 What codes are coming up, scan even if light not on. You said cam singular so it’s a 2.4 engine? Any recent work done to car? Is there a security system on car ? jkeaton 1 Quote Link to comment Share on other sites More sharing options...
Borjawil Posted June 13, 2020 Report Share Posted June 13, 2020 How are you checking for spark? Pull the coil out and place a plug in it. Hard to ground the threaded portion of plug to a metal surface on engine. I took a piece of wire and stripped the ends. Wrap one end on the Tang of the plug or threaded area and another on a metal surface or ground lead. Either have someone crank the engine or place it where you can see it through the windshield. Test a couple different coils/connectors to be sure if its just one or several. If no spark, you say there is power to the plugs. What voltage are you seeing? Resistance? How are you testing for power? Car on, car cranking? If there's a security issue it could kill spark. Also check that you have proper voltage to the cam and crank sensor connectors. Not sure on this vehicle but most cars I've dealt with will still have spark with a bad crank sensor. Usually cam sensor will cause no firing. If you can't verify spark for whatever reason, take a syringe or pop bottle, put a small hole in top and put some gas in it. Put a bit of fuel in a few or all plug holes and crank it to see if itll fire. That or spray some starting fluid in the intake hose to throttle body. Might take some gas pedal work and a bit of cranking to get the spray to reach cylinders. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted June 14, 2020 Report Share Posted June 14, 2020 Or use a spark plug tester. It goes in line with installed plug and coil, flashes light when it gets high voltage signal. Harbour Freight/Princess Auto sells them, not expensive. Less risk of shocking the monkey ? Quote Link to comment Share on other sites More sharing options...
Armando G Posted June 18, 2020 Report Share Posted June 18, 2020 (edited) About a week later and no reply from OP. Guess he fixed it, or not that important. Frustrating part of forums Edited June 18, 2020 by Armando G jkeaton 1 Quote Link to comment Share on other sites More sharing options...
