2005 gmc, sieerra 1500 4.3
have code p0351. starts and runs. not misfire.
replaced icm and coil. bty the coil has a 2 wire connector, not 3 wires.
where is the ground wire I hear about.
P0351 is definitely an electrical problem with coil #1. Sounds like you have the wrong coil. There should be a 3 wire male socket on the coil. Not 2. Maybe you have a boxed wrong defect. Take it back to the store and exchange it. But open the box of the replacement coil and make sure it has the correct socket. Check out the pictures of the coil on rockauto.com. HTH. -Jim
nope, I checked 16 times striped wiring harness. old coil has 3 prongs, knew coil has three prongs but.........pigtail connector has only 2 wires..
