i just did a engine swap on 03 dodge 1500 4.7...truck sat 2 yrs or close to it,,after new engine,,will not start,,get a p0335 code,,checked voltage at crank sensor and cam sensor,,5 volts,,,checked ground to pcm,,all good,,new sensors didnt help,,does anyone know a way to test the 3rd wire to sensors? i would think they should be a ground pulse,,but im getting nothing,,any help would be great thanks in advance!!

 

I would look for chewed wires. Critters will make engine compartments their home. Why did the truck sit after the new engine?
