Since we're talking tundras...my 1998 tundra lt r just quit on me on the way to go fishing. Buzzing along good until the thing just quit like I hit the kill switch. Have spark, fuel and very good compression. Am I looking at trying to find a cdi unit? Any and all help is appreciated!!
If you have spark, fuel, and compression, it should run. One of those must be bad.
When you check compression, are you using the plug? If there is a short or open in the plug, that would pass the test and fail to run. Try a new plug- they are cheap.
Than you say fuel, does it fire when you use starter fluid? If so, you have spark and probably no fuel or bad fuel. Might have gotten water in the lines. and froze it there.
If it is not this things, I suppose it could be the ignition, or maybe the ignition switch or some other part of the ignition causing timing to be bad. Does yours have reverse?
