I had two of them do the same thing. Both as the 120-140K mile mark. A 95 and a 96, both with 4.3 VIN code "W" have the new injection systems at that time - NOT TBI. It is known for all-of-a-sudden no-starts with no previous warning signs. The check valve in the central-port-injection unit needs 43 pounds of fuel pressure to open. The fuel pump in the tank is set at 57 to 61 PSI. If cranking fuel pressure drops below 57 PSI, it usually results in a no-start. It's a Go or NO-go situation. Either it starts fine, or doesn't even try. And, it's hard to diagnose since these pressures are so close to each other. A drop in just one PSI can change a good starter - to a no starter. Most later 1995s have CPI, and most 1996s have CSFI. The only big difference with the latter is - there are more indiviual parts available, and the fuel pressure runs a little higher - 60 to 66 PSI with the key on, engine not running. You need to pull the engine-house off, and stick a pressure gauge on the Schrader valve on the engine. It is put there just for this test. If you don't have the fitting kit, an older air conditional gauge connection for Freon will fit.
