Check fuses, make sure you have a good fully charged battery. Then install new NGK plug. If still no spark, jumper wire from battery + to red/black coil wire (leave connector on coil, pull it back a little to attach jumper). Report back. Share this post Link to post Share on other sites
redhulk2085 0 Posted Friday at 04:11 PM Thank you so much I'm also getting no power to my fuel pump. I used a check light I have ground but no power could that possibly be the relay all fuses are good. Share this post Link to post Share on other sites
jeepwm69 7,721 Posted Friday at 04:38 PM Yep. Try that jumper wire trick. That bypasses the fuel injection relay. See if you get anything with the jumper wire in place. Share this post Link to post Share on other sites
redhulk2085 0 Posted Saturday at 07:24 PM All right I did the trick with jump in the wire I'm still not getting any spark My neutral light comes on and it does spin over by the button but I get no spark I get no power to the fuel pump I tried jumping the angler sensor still nothing changes any other things that I can do or do I need to replace the ECM thank you Share this post Link to post Share on other sites
jeepwm69 7,721 Posted 13 hours ago Doing that jumper wire should backfeed power to the fuel pump, even if the ECU and/or fuel pump relay are bad. Did you get the jumper wire on the coil with the red/black wire still attached and then attach the other end of the jumper wire to battery positive? Share this post Link to post Share on other sites
redhulk2085 0 Posted 12 hours ago Yes I did. But I'm going to try again after I charge the battery all the way up. Share this post Link to post Share on other sites
