By-pass EGR, now no start.. HELP
I have an '04 F250 with 108K. The EGR went out at 60K under warranty, so I had it replaced. It went out again this time at 108K and from what I've read on here, the best thing to do is by-pass it. Which I did (thanks to this site!), along with the oil cooler, which I found to have a hole in it. After installing the EGR bypass kit and a different oil cooler and getting everything back together (after making sure the headgaskets were ok), the truck had trouble starting. Finally it fired up and ran great. There was quite a bit of water in the exhaust and some white smoke at first, but it cleared out after 15 minutes or so. I took the truck for a test drive for about 3 miles and it ran fine except for a couple of light surges (I assumed it was air in the lines or something). I came home, let the truck idle and it immediately starting missing really, really bad. It then surged several times and died. The truck ran fine for 20-30 minutes before it started missing and then about 10 minutes after it was missing before it died.
Now it won't crank. It will turn over, but it doesn't even try to start. I'm not getting a check engine light and I've heard that the dealer can't scan it without the check engine light being on.
Any suggestions? I'm beyond frustration. I'm beginning to think the best thing to do is drive it off a cliff and not jump out.
