My Saturn won't start. It'll crank and sound like it's intermittently trying to kick over, but nothing. Oil was leaking into the combustion chamber from the #1 and #4 cylinder, replaced the valve cover gasket, plugs and an oil change. No fuel pressure, replaced the pump and relay. Killed the battery, got a new one. I have fuel and spark. I have no way to check codes where it sits, prior to this the check engine light was on. 3 months ago, changed the starter and TPS, ended up breaking a plastic hose that connects to the sensor next to the throttle body unit. Since then, the light stays on as a result of that hose breaking, but now i'm not sue if there are any more codes. About 6 months ago, replaced fuel filter, plugs, wires, air filter. I'm out of ideas. Research so far is pointing me toward the CPS or the Coolant sensor.
