2001 Durango with 4.7 has a weird problem. The engine light can on with code 307 and 207 and had no oil pressure and had a real bad smell of gas. I put a new injector in but it smokes really bad and still has no oil pressureand the gas smell is still there. I unplugged the injector and my oil pressure comes back. I'm stuck at what the problem is

 

Replaced and unplugged the injector? You have an injector for each cylinder so I'm a little confused as to what you are trying to explain.

 

P0207 and P0307 refer to the cyl 7 injector. I have nothing to really offer Matt, sorry.

 

I replaced the injector on cylinder 7 since I got that code though maybe it was stuck open. With the injector unplugged my oil pressure is normal plug it back in and. My oil pressure drops to zero and it smokes extremely bad

 

Oh ok, sorry but I do not know how that could effect oil pressure. Maybe electrical and not really oil pressure dropping? That would be my guess.

 

On further investigation I wiggled the wires close to the oil sending unit and the pressure gauge went back to normal so hopefully I can clean it up real good and fix most of the problems!
