Common Problems
Ferrari Testarossa Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Ferrari Testarossa's flat-12 is robust when maintained, but KE-Jetronic injection faults and timing belt neglect dominate UK replacement enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address original failure points - plus a minimum 12-month unlimited mileage warranty.
KE-Jetronic Injection Failure - Why Late Testarossa Engines Won't Start
KE-Jetronic Injection Failure
Most affected vehicles

Ferrari Testarossa Euro (1987-1991, F113B KE-Jetronic)
Failure mileage range
40,000-80,000 miles
Typical failure window
Root cause
Bosch KE-Jetronic protection relay and warm-up regulator degrade with age, causing fuel pressure loss and mixture enrichment errors that mimic catastrophic engine failure.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Injection System Diagnostic & Relay Replacement | £800 - £1,500 | £400 - £900 | Test protection relay, warm-up regulator, fuel accumulator; replace faulty components | Restores correct mixture control if no internal damage; 2-5 year solution |
| Intermediate - Full KE-Jetronic Overhaul | £3,500 - £6,000 | £2,000 - £4,000 | Rebuild fuel distributor, replace injectors, recalibrate mixture, update wiring harness | Comprehensive fix for injection-related running issues; 5-10 year solution |
| Full Replacement - Rebuilt F113B Engine | £22,000 - £35,000 | £12,000 - £18,000 | Supply & fit rebuilt flat-12 with upgraded injection components, bench-tested, 12-month warranty | Definitive solution when injection faults have caused internal damage or cylinder scoring |
Our recommendation
On a Testarossa worth £40,000-£80,000, start with a specialist KE-Jetronic diagnostic. If the engine has been run with mixture errors for extended periods, cylinder scoring may have occurred - in which case a rebuilt engine with injection overhaul is the only reliable long-term fix.
