take the timing cover off and look at your timing mark line up
if you jumped your timing you'll find out why then

the maxima engine has been identified as an intereference engine and valve damage is most likely to occur ( autodata timing belts publication)
timing is unlikely to jump unless the belt breaks or the belt tensioner becomes loose
if there is a timing problem then the engine will be difficult to start , or run very badly
If the motor starts and runs but lacks power or performance or just does not start then it is suggested to have the fault codes read to check for cam/crank position sensors and immobiliser operation

no way of doing so. need to remove cover. i have been doing this since 1996 and have never seen chain driven nissan jump timing. have seen some timing belt cars jump, but never chain driven engines. i think you have something else going on. i have done many and many timing chain jobs on frontiers and maximas, but not for a timing chain jumping issue. upper timing chain shoes wear out and engine gets noisy. i have to say i have seen some with the primary chain stretched a bit, but car still ran fine.

fuel pump /timing belt /computer fault /sensor fault/ to be honest would need my head under the bonnet to have any idea

It can be the alternater but at the same time the car could of jumped time on you but i would try a tune up on it first cause that is the most common problem for a car dieing out

It could be the ignition switch, neutral safety switch,alternator, ignition/starter relay, ignition coil/module.

Check timing belt. Shoot a timing light down at your crank. If the timing mark jumps around bad, your belt has slipped.
