Oil pressure dropping to zero and stalling - 6/6/2007 11:01:42 AM    dannyAZ   Posts: 3 Score: 0 Joined: 6/6/2007 Status: offline My brother in law has a 2000 camaro that has randomly stalled 3 times over the last couple months.  In all cases, the check oil pressure light has come on.  When he checks the gauge the pressure drops to zero right before the car stalls.  This has happened ideling at a stop light as well as while on the freeway.   Any one have any ideas why this would happen ?

Has he checked to oil level? what is the pressure as he drives and at what rpm? The oil pressure may just be droping because its stalling. When does it stall? only when the rpms are already low like when stopping? The fuel pump gets power when running through the oil pressure sender. Oil pressure dropping could allow it to stop but stalling obviously drops oil pressure. _____________________________ Its better to burn out than fade away "Is everyone on DOPE?"

Maybe the fuel pump is going bad. Does he have an alarm that kills the ignition? Tooo may times I see those go bad and leave people stranded. _____________________________ Its better to burn out than fade away "Is everyone on DOPE?"

Do you think it could be a faulty oil pressure sending unit or the oil pump going bad ? (in reply to MadMikeZ28) Post #: 5
