If your oil pressure light comes on while engine is at an idle, maybe 10-40 is too low of a viscosity for your engine. I'd go to a 20-40 or 30-50 and see how the oil pressure does. make very sure you have the correct filter, some "factors" did for a while produce the wrong filter for certain vauxhall engines, these filters did not have a bypass and would cause light to come on, would couse catastrophic engine loss if not sorted. suggest recheck filter and obtain one from main dealer if not already done so. possible blocked oil pick up pipe in sump ,not uncommon if infrequent oil changes ..............PS i had this problem you made need to change the oil pressure monitor switch just on the top, front of the engine, it also appears to leak oil when the switch has gone!
9 to 13 LBS (PSI) Correct answer is that if it is a 1996 to 2000 the correct fuel pressure is 60 to 66 with key on and not running 55 to 58 with it running at idle.
Assuming it is a fuel related problem, the fuel pump may be running but it may not be putting out the correct pressure. Have the fuel pressure tested, it should be 60 to 66 psi. Also be sure the fuel filter has been changed.
Fuel filter, fuel pump, or pressure bypass/relief valve is not providing the correct, enough fuel pressure at the injectors.
Keep breathing when your running
Im still running ! it's been 4 days
It is 28-45psi with engine running and 35-45psi with key on engine off.
I am so grateful for my friend's never-ending support; their encouragement is what keeps me from stopping.
9 to 13 LBS. NO HIGHER ARE LOWER. Are you will have starting and running problems.
Check the ignition coils and the crankshaft position sensor. One of these could be failing as they heat up.
Need to run a fuel pressure test. Specs. are 9 to 13 LBS. You could very well have a bad fuel pump. CHECK PRESSURE.
