There is a good spark at the right timing (now well before on 12"). Not sure how to check the Ignition AMP? Getting a consistently good spark... There is correct fuel pressure on the fuel rail, no visual leaks. Smell patrol at the exhaust after starting so its getting fuel through the cylinders . Not sure how much though... smells like too much Checked the coil -ve Voltage on the back of the ECU connector: reads 10 Volts (so within 9.5 +/-1V). Not worked my way through all the diagnoses steps yet (up to step 8). Checked temp sensors both readings correct 14 and 15 degrees C. Need to finish the other steps of the diagnoses but above baffled me as I seem to get all ingredients: compression, spark & timing, fuel.... not picking up at all. Can the ECU/injectors flood the engine so quickly that it doesn't pick up even? Have not yet checked the signal on the injectors with a light. Could they be open all the time / too long pulse? I guess I have to pick up at step 8...

Thanks for all the suggestions! I will be working on my LR tonight checking the ignition amp, coil -ve lead to ECU and work my way through the 3-1.9_Hotwire_System_Diagnostic_24_tests.pdf steps (includes temp sensor). Will post any findings tomorrow.

Hi, My range rover (1993 3.9 EFI V8 ) cranks, seems to catch on, but won't start. Engine stopped while driving (after 5 minutes) and wouldn't start. Been having stalling problems before when idling (with hot engine) where the tachometer would suddenly drop before the engine died. Have checked the ignition; sparks on all plugs are good. Have had the alternator checked (was suggested because of sudden tachometer drop) but no problem found. There is fuel pressure and the injectors all click on signal. The ECU does not show any sensor problems. Switched the airflow meter with one from a running RR. Kind of out of ideas... Any suggestions on where to look further? Thanks, Onne
