Difficult To Start & Engine Cranks Normally

On Avalon, Camry, Camry Solara, Corolla, Highlander, Land Cruiser, MR2, RAV4, Sequoia, Sienna, Tacoma, Tundra and 4Runner, check starter signal circuit. See STARTER SIGNAL CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article.
On Celica and ECHO, check starter signal circuit at STA terminal on Engine Control Module (ECM). See WIRING DIAGRAMS article. For illustration of ECM location, see THEORY & OPERATION article. No other testing information is available from manufacturer.
On Avalon, Camry 2.2L 4-cylinder gasoline models, Camry 3.0L V6, Camry Solara, Celica, Corolla, ECHO, Highlander, MR2, Prius, RAV4, Sienna, Tacoma, Tundra 3.4L V6 and 4Runner, check fuel pump control circuit. See FUEL PUMP CONTROL CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article.
On Land Cruiser, check fuel pump control circuit. See DTC P1200: FUEL PUMP RELAY/ECU CIRCUIT test in SELF-DIAGNOSTICS - LAND CRUISER article.
On with sequential manual transaxle, check throttle body and components for Electronic Throttle Control System (ETCS). See THROTTLE BODY under IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article. Models with sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
On Sequoia and Tundra 4.7L V8, check fuel pump control circuit. See DTC P1200: FUEL PUMP RELAY CIRCUIT test in appropriate SELF-DIAGNOSTICS article.
