99 F350 7.3 Dually
Please help. To start with, I know nothing about trucks. When it has a problem I take it to the 'guy' - a mechanic in my town. So with that in mind, please be gentle.
Let's start about 2-3 years ago, my overdrive light starts flashing, truck 'sounds' funny but still goes. After a few trials of different things I found that before turning over, I have to wait for the 'ding ding' of the glowplug preheat to finish and then wait for the radio to come on, then I can turn it over. The problem is intermittent so it doesn't always happen. If I don't wait, the speedometer doesn't work, o/d light flashes and truck 'seems' funky. In this time I have taken it to Ford on several occasions and different locations as well as asked other mechanics - they cannot seem to replicate the problem nor find what it is. So I have lived with this, it just takes me a little longer than everyone else start my truck. I tell you this in case it is indeed something or if you have any ideas.
In the last year, I have had to replace the 2 batteries only to find that was not the problem, the alternator was. I had been to Napa, autozone and O'reilly's and run through their scans as well as an diesel repair shop. After getting a dud brand new one from O'reilly's, which they did replace and is now working fine, still caused a few headaches in the mean time. A week later the truck starts shaking violently while driving I took it to the diesel repair shop again and had to replace the (excuse my ignorance) knuckle looking thing under the truck right in the middle (forgive me and can't remember what it was but apparently is was major).
Finally it seems I am at rest, quite a few dollars spent but the old girl seems to be running fine.
Now, 2 days ago. Hubby starts truck and it just dies. No gauges, nothing. We take it to our guy via trailer, while unloading they notice a diesel leak from underneath, they changed seals on something and it seemed fixed they check everything on the scanner and all is good. It idled fine then he took it for a test drive and it dies. He had a ford tech friend of his come over after hours last night and even he couldn't find a fault. The diagnosis is that now the computer needs replacing, we don't have a quote on that just yet (we just got the news) but I assume it's the big bucks. Before we look into that, I wanted to see if you guys had anything similar.
It's a sketchy history I know and I apologize. I have only just stopped crying my eyes out at this recent news. I have had my truck for 10 years now and I am kind of attached beside the fact that now is not really a good time to be spending so much freaking money. Please any help?
