I have a 94 ford ranger 4x4 with an engine out of a 2000 Ranger. I know its a v6 and i am pretty sure its the 4.0 but i am not sure whether its sohc or ohv. Its a 5 speed manual. I have extremly low oil pressure and my truck has been shaking really bad sometimes when i drive. Most of the time this is when i first start it up, and now its starting to die when it happens. Also i was wondering if getting 18 miles to the gallon on the highway is normal? Any help would be great. This is my only daily driver right now, i need to get it fixed.

 

18mpg highway is about right. If the motor is a 2000, then I believe it's an OHV. Other than telling you to check the oil level, which I'm sure you already have, I can't help you much.

 

My buddys ranger did that then all of a sudden blew the oil pump and seized the motor.

 

Any CEL`s...?

 

yeah but its intermittent. It not throwing and hard codes, so I am unsure of what the codes may be. I was thinking its probably the oil pump but i am not sure.

 

do a oil pressure test that will tell ya if the pump is geting weak

 

Also do a once over on all your vacuum lines - even 1 misplaced or cracked line can cause havoc all over the engine... shaking, sputtering, rough idling; and as above, do an oil pressure test, that should verify if its the pump

 

cool those all sound like great ideas, ill let you guys know how it turns out.
