First check the oil level and top up as necessary. If the oil pressure is at 0 , then it would very quickly sieze the engine, that not being the case, it sounds like you need to replace the oil pressure switch/sensor, which will be mounted either on the engine block or on the oil filter housing. Hope this helps
You probably recently had a new key made, and the Jeep ignition is chipped. The key has a sensor, and must be programmed to match the ignition. Some will start till you put it in gear, then it shuts off.
I think you have a bad ground on your engine gages...but, more importantly, have your oil pressure checked by a mechanic. If it is indeed only 20 pounds the engine is sadly on it's last legs.
When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect. If you haven't described a clear and precise description of the defect you decrease the chances of an accurate reply. Thank you.
have a 2000 jeep grand cherokee with 84,000 miles. started having issues with oil pressure gauge going crazy up and down, beeping. had oil pump replaced per mechanics recommendation. didn't help won't hold pressure---only registers about 2. now they tell me i need a new motor!!! just bought vehicle less than 1 yr ago...had carfax clean report!!!!any suggestions?
At idle, at operating temp is there any ticking from top end of engine? Are there any knocking noises brom bottom end? If no noises, change oil and add some Marvel oil to clean out galleys. If that dosent work, change oil pressure sendingf unit. Also, if you have a mechanical oil pressure gauge, hook it up and take a direct reading. Oil pressure (in any vehicle) at idle should NEVER be less than 15psi. Generally in 4.0 jeep engines it's never less than 30, with a high reading at driving rpm of about 40-60! (but, you did not mention what engine you have)
