Hello, i have a 1990 Volvo 740GL that died on the highway. It just quit running. The car has a new timing belt installed a year a go. It has a new fuel pump relay. A new crank sensor, a new fuel pressure regulator. It has spark & you can here the fuel pump kick on every time. The timing has just been checked also & it's fine. After it died on the road & was towed back it started & ran for a minute or two then died. If it sits overnight it will fire for a second & then that's it. After that it won't fire at all. The mechanic couldn't figure it out so i ran codes & got a 122 code which says it's a faulty air temperature sensor so i was desperate & ordered one online. I just don't think that a faulty air temp sensor is going to make it not start at all. It's 80 degrees her in MN & it won't fire unless i shoot starting fluid in the throttle body. Could a faulty air temp sensor make it not start at all? It gives me the 122 code which says it's faulty. Before i forget, i have the Regina system. Anybody please help! I need an answer now...
