cold engine starts

When I start my car it cranks and wont turn over until the oil pressure gets to about 40-50. Is this normal or could it be a battery or a starter problem. I thought it might be the plugs,but I changed them along with new wires.

Re: cold engine starts

You see the oil pressure come up because the oil pump is beng driven once you begin to crank the engine. That is normal. Sometimes a carb will experience a leak-down type of effect and a little cranking is necessary to "refill" the carb before the car will start. Some cars you can get in and the car will start almost immedately. Sometimes it is a choke issue and requires extended cranking to start... The only time I can think of it being an oil pressure issue is if you are running like 20W50 in a freezing climate and the engine may be a encounter a little resistance from the thick oil .. When the car sts overnight, does the choke engage when the throttle is operated. Does it immediately squirt gas? Look for any kind of vacuum leak also....

More details. Engine, carb? The oil pressure just gets up there because it is cranking so long.

Re: cold engine starts

Oil pressure and starting aren't linked in any way; sounds like a basic tune-up is in order, including choke adjustment.
