Why GM’s Cross‑Fire Engine Got the ‘Cease‑Fire’ Nickname – Reliability Explained

Bottom line: The early‑80s GM Cross‑Fire fuel‑injection engine earned the grim nickname “Cease‑Fire” because of chronic reliability problems that left many owners stranded.

Design & Looks

The Cross‑Fire was GM’s first attempt at electronic fuel injection for V6 and V8 blocks. It used a “cross‑fire” manifold that sprayed fuel into the intake ports from opposite sides, a look that seemed high‑tech at the time. However, the design was rushed, and the injector seals were cheap‑grade. That small detail turned into a big headache.

Performance & Mileage

When everything worked, the engine delivered decent power – about 140‑170 hp for the 4‑cylinder versions and up to 210 hp for the V8. Fuel economy was modest, roughly 18‑22 mpg in the city. The real issue was consistency. Faulty injectors caused misfires, and the engine could literally “cease‑fire” while you were driving. Owners reported loss of power, rough idle, and, in worst cases, total shutdown.

Price & Rivals

When new, the Cross‑Fire‑equipped cars were priced a bit higher than their carbureted cousins, promising better efficiency. In practice, buyers paid more for a system that required frequent repairs. Competitors like the Chevrolet small‑block V8 with a carburetor, or the early Honda D15 fuel‑injected engine, proved more reliable and often cheaper to maintain.

FAQ

What was the average mileage of the GM Cross‑Fire engine?
Typical real‑world fuel economy was about 18‑22 mpg in the city and 25‑30 mpg on the highway.

Why did the engine get the “Cease‑Fire” nickname?
Because failing injectors often caused the engine to lose power or stop running completely, leaving drivers stuck.

Is a Cross‑Fire engine worth buying today?
For most enthusiasts it isn’t. The cost of parts and the risk of sudden shutdown outweigh any nostalgia value.
