After replacing the brake system and the fuel delivery system, I have my '93 XR2 driving and stopping. It goes like stink now, the problem is it won't start. On initial startup, I had soaked it a few days in Marvel Mystery Oil, spun it to get oil pressure up and was pleasantly surprised at how quickly it started. Yeah, lots of smoke signals, but it fired right off. A couple of days later, it spun really fast and I figured it had broken the 30YO timing belt. Big surprise, no broken belt, just no compression. If you grind on it for a while and come back in a few minutes, you can get it to fire off on one cylinder, keep your foot in it and after a little, a second cylinder and so on. After it finally catches on, it runs like a bat out of hell.....sorry about that. The turbo kicks in in the low 2,000's. It runs good. Turn it off and it fires right up. Wait a couple of hours and start grinding again. My mechanic thinks the lifters are leaking down. My problem with that is no lifter tick, cranking or after it initially fires. I'm afraid it stuck rings. Anyone got any other ideas. Sorry for the long post.
