Hi OURCHILD09 and TY for the donation

Do a fuel pessure check, the specs calls for 36psi

See below:

FUEL PRESSURE CHECK

When reconnecting fuel line, always use new clamps.
Make sure that clamp screw does not contact adjacent parts.
Use a torque driver to tighten clamps.
Use Pressure Gauge to check fuel pressure.
Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false readings
Release fuel pressure to zero.
Disconnect fuel hose between fuel filter and fuel tube (engine side).

Install pressure gauge between fuel filter and fuel tube.
Start engine and check for fuel leakage.
Read the indication of fuel pressure gauge.
At idling:

With vacuum hose connected:
Approximately 235 kPa (2.4 kg/cm2 34 psi)
With vacuum hose disconnected:
Approximately 294 kPa (3.0 kglcm2, 43 psi)

If results are unsatisfactory, perform Fuel Pressure Regulator Check.

Hi, Thank you for your answer but when I checked it the fuel pressure is within normal operating psi but the car still wont start it just will turn over.

Check the fuel pressure to rule out the fuel pump and comeback with the readings

Hi, The fuel pump is working fine and it has good fuel pressure but I went ahead and got a compreesion tester and the readings from it through me off it says 0 compression and to make sure the teaster wasnt broken I tested it on my 2007 cobalt and it showed 120 psi soim guess from the cold or something her gasket blew but it drove fine with no problems prior to parking it and also there is quite a bit of coolant leaking from it as it sits and I also pulled the oil dipstick out and it has about 95% gas in it I mean the oil is just full of gas I even drained some out to check it and it is just awful I dont know if that came from them trying to start it for two hours straghit or what she informed me today that her gas mileage was decreasing dramatically over the past few months from a full tank would last her for about 2 1/2 weeks of driving to almost 1 week so I dont know what happen and I know by now the car just needs a new engine or rebuilding this one so do you have any suggestions to which one I should do. Thank you
