Spark. YES/NO?
- suggestion no.2 , -IF- No answers to questions: tow to $hop
- suggestion no.3 (after answer to no.1) will be for injectors; do each click while cranking? (Listen: if u have screwdriver, place it on injector, ear on handle - or 'invest' in mechanic stethoscope 5$)
- suggestion no.4: Which one is cheaper: 2hours trblshoot for nothing, or buy 10$ multimeter, ask salesman show to measure voltage?

I am sorry i could not do testing as u mentioned, i borrow multimeter from my friend & check couple of sensors readings were good. Then i frustrated & took to shop. My mechanic told me today as they check compression pressure in each cylender & they see its too low for 3-4 cylenders. They do test timing & eveything & suspect it could be engine motor that is bad, which need to be replaced. Appx estimate including labour with reused engine motor part it will cost me 1500-2000 $. He will give me complete estimate tomarrow once he will get price for motor. I dont know if i should take it to nissan dealer or take second opinion as its almost 2 weeks now i am without car...
What do u think if some cylenders giving low compression pressure reading. From Maunal i fould following....
If pressure stays low Piston Rings may be worn or damage - Replace them or...Valve may be steaking or seating improperly inspect & reapir valve & valve seat
If compression stayes low in 2 cylenders that are next to each other then cylender head gasket is leaking or both cylenders valve component is damaged ... Inspect & rapir as necessary... i dont know how motor comes into picture in cylender pressure...
Pl guide me on this , appriciate ur great help always , thaks in advance...
Thanks
