1992 Nissan Sentra

Reader Question: Hello,

I have a 1992 Nissan Sentra that wont start. It is firing, seems like it might have something to do with the fuel pressure not sure though. You can crank the engine it will not hit. If you take the fuse out for the fuel pump it will begin to hit but will not start. I have installed new plugs no help.

Thanks for your help!


Hey there Randy,

If the engine will not start, you are missing one of the key ingredients…spark, fuel and compression.

I would first make sure you have a good strong start at the spark plugs…if not, check the ignition coil and distributor.

If you have a spark at each spark plug, then check fuel pressure at the engine. You can rent a manual fuel pressure gauge from your local auto parts store. You should hear the fuel pump prime itself when you turn the key to the ON position. If you do not hear a 2-second “whine”, when you turn the key to ON…then check the power TO the fuel pump.

If you have spark and fuel to the engine, then I would look at compression and ignition timing next. Does the engine sound like it is spinning over easier than normal? If so, you might have a broken timing chain or it could have “jumped time”.

You might also want to check engine compression just to make sure there is not an internal engine problem like a blown head gasket or a valve train problem, which is affecting compression.
