hey everyone im chasing a weird one here. truck has 8 new injectors and new ficm. truck runs great then once its left to idle it will shut off within 2 minutes of idling.it then will sometimes resart and then sometimes not for hours.when it does happen it will no longer crank as well for a few attempts then it will crank and still not start. when this happens I only have a continuous memory code u105 and u306. my ids will not see key on power and will not communicate either then once it starts to crank again ill have communication again and my data show 0 volts on all ficm pids.has anyone else run into this and possibly help so idont have to go crazy lol buried
