yakimich Posted December 1, 2009 Report Share Posted December 1, 2009 I do have the same similar problem up in Washington State where it is now getting cold. My 88 had supposedly gotten fixed by rewiring up to the injectors because I was told they were cracked and frayed. It did run great all summer season and just wouldn't start up again today. Have spark and fuel even tried removing the over the head intake to feed it fuel and no go. Other than that I can't tell you what fixes it.

JAinsworth Posted December 1, 2009 Report Share Posted December 1, 2009 I would suggest checking the isc and resetting it first, then check the cts. Link to comment Share on other sites More sharing options...
