Hi guys!
I have recently encountered a few problems with my 2004 Land Cruiser 120 LC4 3.0 D4D.
The vehicle has covered 95,000 miles, and has been with me for the last 5 years and 20,000 miles.
Recently the car took a little longer to start than usual. I didn't read too much into it, as it was the first night she had spent outside in minus temps for 2 years. However, the next day, after driving for about 5 mins, I noticed that the check engine light was illuminated. I pulled over, switched off, re-started, and all was fine. 2 days later, I started the car, and the check engine light was illuminated again. When I left my parking area, I found the car would not accelerate past about 15-20mph. (perhaps this is some sort of limp home mode?) Anyway, I crawled along for around five minutes, when after a few very slight surges, she started running fine. I pulled over, switched off, started again and the check engine light was gone.
As I don't have a code reader, I checked the blink codes and retrieved error code 78. These appear to be:
P0093 (78) - Fuel system leak (Large leak)
P0627 (78) - Fuel pump control circuit (open/short/failure)
P1229 (78) - Fuel pump fail.
There are no visible fuel leaks, and I don't have any smoke on start-up, or during driving. The problem seems to go away when the car is warm, and on occasional days it doesn't occur at all. The vehicle is parked in a basement, and never really experiences temperatures less that +10 degrees centigrade. I recently filled up with standard diesel for the first time (the fill-up before last), after normally only ever using a 'super' or 'premium' product. The car and I are from the UK, but currently live in Bulgaria, so fuel quality could be an issue. She is regularly serviced in terms of oils and filters every 5000 miles, and I fitted a new timing belt at 90,000 miles (5000 miles ago).
Obviously, I'm dreading the cost of replacing the injector pump, but if that is the case, I want to be certain that is indeed the issue. I just wondered if you guys could suggest a way to troublshoot the problem a little more in terms of things to check. I have a Toyota main dealer about 3 hours drive from me, and I'm a little worried about risking the drive - plus, I'd really like to try and fix the problem myself if possible as I do love working on the old girl.
Thanks in advance for any advice you guys can offer.
