I have a 1994 LHS w @170K miles. Engine turns over yet Will not start at all. Checked and have spark at number 1 cyl., have fuel pressure and no codes when keying several times. Replaced plugs and plug wires as plugs were worn pretty bad. Verified that cam belt is not broken as both cams spin when engine is cranked. Do you have any ideas????
