With all plugs removed from engine and using only the starter to rotate the engine, I am getting no spark on three plugs. Two plugs (No. 1 and 5) appear to be sparking faster than should be and the no. 6 plug appears to be sparking normal. I swapped coils around and it does not appear to be either spark plug or coil related. Put O-Scope on ECU signal to no. 2 and no pulse was present. The No. One was pulsing more than it should have (which represented why it appeared to be sparking more than normal). No trouble codes are indicated by the ECU. This is a 1997 engine that I installed (replacing a 1995. Both engines are 30DE engines. The only code on the ECU prior to engine swap was the air intake temperature sensor (which was disconnected). After reconnecting and resetting ECU codes, there are now no diagnistic codes. Any help would be appreciated.
have the same problem?
