Question about 2008 Chevrolet Cobalt
Replaced: Fuel filter, fuel pump, spark plugs, Camshaft positioning sensor (code thrown)
Posted by Anonymous on
The items needed for start include: spark to the plugs. fuel pressure and volume to the injectors. timing and compression on all cylinders. rotation of crankshaft from the starter and pulsing of the injectors by the computer.

What code did it throw ? When are you people going to learn to test thing's instead of just replacing parts ? You could have take it to a ASE certified repair facility had it fix cheaper then just replacing those parts ! You think you know something but you don't ! Does it have spark ? did you check to see if there is battery voltage going to the fuel system circuit ! Does it have a fuel pump relay or like ford's have a fuel pump driver module an a inertias fuel shut off switch ! You don't ever tell us what make, model an year it is !

Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located before the catalytic converter? The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!

If the engine
cranks over normally when you attempt to start you car, but the engine
does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION.
The engine needs adequate fuel pressure, a properly timed spark and
normal compression to start.
1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.
2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.
3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..
