MY CAR TURNS OVER,BUT DOESN'T START. I CHECKED FOR FUEL IT HAS FUEL AND FUEL PRESSURE. IT ALSO HAS SPARK. I BROUGHT IT UP ON TDC AND CHECKED THE ROTOR AND IT POINTS TO THE #1 WIRE ON THE CAP. COULD IT BE THE IGNITION MODULAR? I AM LOST. PLEASE HELP! THANK YOU

Only #1 was full of gas? Compression test, then it might be a stuck injector or no spark to that cyl

THANKS FOR THE REPLY. I SHOULD HAVE TOLD YOU ALL THE CYLINDERS HAD FUEL IN THEM. ALL THE SPARK PLUGS ARE FIRING. THE CAR WILL NOT START. IT JUST CRANKS AND CRANKS. THE CAR HAS FUEL AND SPARK. IT DOESN'T FIRE UP.

hows the compression? Just last week I did a head gasket on a Nissan that was doing the same thing. Head was a little loose, leaking compression between all the cylinders

Suggested Repair

Perform a compression test on all cylinders. If compression is low or leaking between cylinders, inspect for a loose cylinder head or failed head gasket. Also confirm injector pulse.

Conversation Summary

The owner of a 1992 Nissan Sentra said it cranks but will not start despite fuel pressure, spark, and correct rotor alignment at TDC. All cylinders were wet with fuel and the plugs were firing. The expert advised checking injector pulse and compression, noting a similar Nissan with a slightly loose head and a head gasket leaking compression between cylinders.
