  • Pontiac Fiero Engine Won't Start With a Hot Engine: Its Causes and Solutions

    Built between 1984 and 1988, the two-seater Pontiac Fiero sports car was fitted with either an LR8 inline-4 engine or the L44 V6 in the mid-engine configuration. This has made the Fiero the only mass-produced mid-engine sports car in history, and thus a valuable collector\'s item. However, its unique configuration has also laid host to a variety of problems unique to the Fiero. One such problem is difficulty in starting a hot engine. This sometimes leads to the engine dying suddenly while running, which could prove to be difficult if you are on the road.

    Its causes

    A hard-to-start warm engine in a Pontiac Fiero is commonly related to fuel problems. In particular, it is caused by water vapor trapped inside the engine. Water mixed in gasoline inside the engine will evaporate because of heat, and if there is too much vapor circulating inside, it will prevent the engine from burning fuel properly, and thus fail to ignite a spark. In addition, a hot environment coupled with a hot engine can also cause gasoline to burn up faster than normal, resulting in increased water vapor that blocks the engine.

    A clogged air intake can also be the cause of your Pontiac Fiero engine stalling when hot. If the filter is too clogged with dirt or debris or is damaged, there may not be enough air to reach the engine intake manifold, resulting in an inadequate burn that will cause the engine to stall or stop working altogether.

    Fixing the problem

    If you are having difficulty in starting a hot engine, the simplest way to fix it is to simply let the engine cool down for several minutes. This should allow the water vapor to condense and mix back with the gasoline and let the engine burn it as normal. You can also try switching to gas from another station; gas refineries typically change to fuel with higher volatility during the summer months, but the fuel may not be distributed evenly to gas stations. Also, if you haven\'t used your Fiero for at least a month, you should flush the fuel tank and engine of gas and refill it with a new one. If left unused for prolonged periods of time, water from the gasoline will actually start to separate and prevent combustion.

    On the other hand, if a clogged air filter is the culprit, cleaning the filter should be able to fix the problem. The Fiero\'s stock air filters are washable, but if the filters are already too dirty or the intake has a disposable air filter, you will need to replace it instead.

    Preventative measures

    Besides being a nuisance, starting difficulties due to excessive water vapor can also lead to a worse problem like corrosion. So if you encounter such problem with your Fiero, have the engine inspected for rust. You can also switch to engine oil with rust-inhibiting properties to minimize the onset of rust.
