Some time this drop is very low that Stopped the Engine and its diffcicult to start it again, I have to press many time gas and switch in order to start it. And VDC and SLIP lights came on. And I have to wait with ENgine Stop to take them off. What is wrong with my Nissan??

Hi Im David......the vdc and slip indicates either low brake fluid or you need brakes. now about the engine problem, these 4.0 engines use oil pressure to control the operation of the timing components. replace the engine oil and filter immediately. if you still have issues after that have the oil pressure tested with a gauge. its possible the oil pump is starting to wear out

i see that you already changed the oil, did you use the nissan recommended oil and filter?

Another info, I replaced the Engine for another one (from Junk store) It was working fine, but suddenly this Oil Press issues started. Yesterday, the Oil Pressure dropped to low that Stopped the engine. And it was diffcult to start again, I had to pass ingition switch and press many time the gas (as old car) It could be problem with the Fuel Pump?? Also I noticed VDC and SLIP ligth came on... And turns ligth also are working strange... All this problem, Could be bad configuration with the Computer and new Motor?? Or its casuality plenty of issues and errors with Oil Pressure Drop??
Expert:  david craig replied 11 months ago.

oh ok then. i think the first thing that needs done now is a compression test.... make sure theres oil in it before doing the test though. if it was an exact same type of engine then the computer shouldnt be the culprit

Hi... I read the failure code and it said the cramshaft sensor of bank 2 was bad... Tofay i will replace it I let u know thx
Expert:  Jay replied 11 months ago.

When you replace it, make sure you get the part from the dealer. After Market electrical parts never work right.

Let me know how you make out and if you need any more help with this.
