Hi everyone,

Car came in as non-runner, engine momentarily starts then cuts out after about 2 secs. Serial codes are P1305 - Ignition circuit current.
However by introducing carb cleaner into throttle body I can keep engine running for as long as I like (or until carb cleaner runs out!)Scoped the injector signal and that is disappearing after 2 secs but still have battery voltage at terminals. Do these have clear flood mode? I tried disconnecting the TPS but it made no difference, there are four wires on the TPS I take it one is reference volts earth and sig out, what's the fourth one for?. Are the injectors operated directly by the ECU or is there something I'm missing.

Any help greatly appreciated before I send the ECU for testing.

Mark
