Graydon, I had an '87 5kcstq that had the hard start problem and I took it to the dealer to have the problem fixed. They replaced all five injectors and that did fix the problem. Not worth the $500 they charged me for it however. I have since purchased a gauge set for fuel injection systems and do all my own F.I. work now. Just my $.02. Mike Loeks '86 5kcstq Squared
