Buddies truck was running fine. Parked for a few hours now no start. Changed the fuel and air filters as well as the cps. Still no start. No tack while trying to start. Fuse number 10 under the hood was blown and replaced. No joy. Oil reservoir is good and fuel in the bowl. Scanned codes with an sct and got P1670 EF signal not detected....Any ideas on this code? Putting it on the gooseneck in the morning. Any ideas on what to look at when I get there? I have an idea but Im keeping my mouth shut!!
