You need to first check the fuel pressure with a gauge. It MUST have 60 to 66 LBS. of fuel pressure to run. IT CAN'T BE ANY LOWER ARE HIGHER NOT EVEN A POUND EITHER WAY Are you will have problems. See if it has 59 LBS. then there will be fuel in the fuel rail but it still won't run. Ant time you have a problem with a fuel injected engine check fuel pressure FIRST with a gauge.
the fuel pressure (key on engine off ) for a 2002 Malibu v6 is ==2000 and later is 52 to 59, have a good day!!
key on engine off 52-59 psi
on v6 engines it is----1997 through 1999---41 to47psi-------2000 and later it is ------52 to-59
The oil pressure sending unit on a 5.9L V8 is on the top rear of the engine next to the distributor.
The fleetline is a passenger car model. Perhaps you mean fleetside. The Fleetside is a truck model. The 59 Chevy Fleetside short bed pickup truck has a 114 inch wheel base.

Locate fuel rail test port which is very close to the backside of the power steering pump/reservoir. Remove dust cap from test port. Thread on a fuel pressure gauge assembly. Be ready with a rag to soak up some fuel that may squirt out as you make the connection. Once you have the gauge installed start the engine. Pressure should be 45-50 psi at an idle. Briefly disconnect the vacuum line at the fuel pressure regulator while engine is running, the pressure should peak to 59-60 psi. Note, Check vacuum line for fuel leakage when you disconnect it from regulator. It should be dry, if not replace regulator.
fuel pressure ( key on engine off )--2.2 four-cylinder engine--50 to 60 psi , 2.4 engine--97 and 98 41 to 47 psi , 99 and 2000 with egr 41 to 47 psi, without egr 52 to 58 psi, 2001 53 to 59 psi,===v6 engines, 97 to 99 - 41 to 47 psi,--2000 and later 52 to 59 psi, have a great day!!
