I have a 95 of a friends here at shop,they put a new high pressure pump in.It was not running before,now it runs,but if it sits a few days will not crank.He said he can fill the oil pump with oil and it will run.If you drive it every day its ok,any thoughts? thanks richie

 

You put an oil pump in it from a 96+, you need one built for a 95

 

The 95 pump has a check valve in it. 96+ the check valve is in the block
