My 940 stopped while idling last week and won't restart. I have tried all of these things to sort it out. It has spark at the coil and plugs, It has around 40 psi on the fuel rail. A vacuum on the FPR does reduce the pressure a few psi. It retains fuel pressure on the rail overnight (20 psi). I checked the timing belt and all the marks line up. The compression is around 170 on all cylinders. The injectors all seem to spray, When I pulled the injectors out and turn the crank manually they pulse fuel. The plugs were black and wet with fuel so I have replaced them. There are no codes set, although the battery was discharged and I think I might have held the button down too long when checking codes the first time and accidentally cleared them. I also checked the resistance of the CTS and it was 3900 ohms. It was idling a bit rough for a few days before it died. I am thinking that the oxygen sensor doesn't com into play until a minute or so after start. I haven't tried ether yet. Any ideas?
