1993 Nissan Altima Problems
The camshaft driven distributor can leak oil and cause a malfunction of the crankshaft position sensor. The engine may crank but not start or run very poorly.
Failure of the ignition power transistor can cause a "crank-no start" condition.
Regular maintenance is recommended to avoid timing chain failure. Rattles may develop in higher mileage vehicles. Regular oil changes will help reduce the incidence of this problem.
Nissan issued a recall on the fuel pump for premature failure. There was an owner notification program and labels were placed on the fuel pump access panel and next to the AC charge label in the engine compartment.

RepairPal Expert Overview:
Nissan is recalling 1993-1994 Altimas because engine movement can be transmitted to the airflow meter/filter housing and support bracket, which can cause the throttle cable housing to pull out of the cable guide. This may prevent the throttle from returning to the idle position when the gas pedal is released, resulting in loss of throttle control that can cause an accident. Nissan will examine and repair/replace the throttle cable housing, insert a rubber stopper to maintain position for the cable, and replace the throttle assembly, if necessary.
