No spark cold,after cranking for about 30 seconds will start rough and blow smoke.Have replaced,crank sensor,distributor,wires,plugs,ignition coil still having problem. no codes ? anyone ?
might also want to check your EGR valve that was not the problem with mine either but if its not. i had to replace the fuel pressure regulator. its got 2 bolts on the front side of your EFI lines. you have to drain the fuel pressure before you do it, there is a inlet in the middle of your EFI rod. get a rag and a screwdrive (like your draining air out of the assholes tires) and then take it off put a new one on. should fix t.
