Hi all,
my Prado95 Petrol/LPG makes me crazy. After a couple of days on Fraser Island (offroad & creeks crossing) the car was fine until Surfers Paradies.
After starting the engine and running for about 3-5sec the EFI fuse (15AMP) blows. Because the ECU is on the same fuse, no fault code could be stored.
I googled a little and some reasons are a short in the o2-sensor wiring, but my engine did not have o2-sensors (I did not see where there should be), so I think a have co-adjustment.
In my case, finding that short is understanding whats happening.
So guys: what’s the process of time when starting an engine?
- Ignition off (EFI relay open, COR open, Low temp sub fuel relay open, Fuelpumpselectrelay is on main tank pump but powerless because COR open)
- Ignition on (EFI relay close, COR close, Low temp sub fuel relay close)
-
But what happened after ~3sec? FuelTankchangeover? Because of LPG I have no main tank. I don’t know if they bypass any switchover parts.
I think I can here a relay clicking before the fuses blow again.
Any ideas?
Cheers
