Check the connectors on the transmission, on the right side is the trans position switch, see if it's full of water. Can you determine how high the water got? Check all connectors to that level, This is a no spark problem? Check engine fuse box too.
HARD STARTING (CRANKS OKAY) If vehicle cranks okay, but is difficult to start or starts and immediately dies, check the following items: Ã Â Â Ensure sufficient secondary spark is available. Ã Â Â Ensure distributor pick-up coil resistance is within specification. Ã Â Â Ensure distributor pick-up coil air gap is correct. Ã Â Â Ensure ignition coil resistance is within specification. Ã Â Â Check for low compression. Ã Â Â Ensure no vacuum leaks exist. Ã Â Â Check fuel pump or circuit opening relay. Ã Â Â Check fuel pressure. Ã Â Â Check for faulty in-tank fuel pump check valve, allowing fuel from lines to drain back to tank after engine has stopped. Ã Â Â Check EGR valve and solenoid operation. Ã Â Â Check air intake system for restriction. Ã Â Â Check for cracks or poor connections at throttle body. Ã Â Â Ensure ignition and valve timing are correct. Ã Â Â Check for faulty spark plug wires. Ã Â Â Ensure noise suppressor (if equipped) has correct resistance. Ã Â Â Check operation of air induction valve (if equipped). Ã Â Â Ensure Coolant Temperature Sensor (CTS) has correct resistance. Ã Â Â Check Throttle Position Sensor (TPS). Ã Â Â Check Manifold Absolute Pressure (MAP) sensor. Ã Â Â Ensure all fuses are okay. Ã Â Â Ensure Idle Air Control (IAC) valve is operating correctly. Page 1 of 1 TESTS W/O CODES -1993 Geo Tracker 8/16/2008

(2) With .035" (.89 mm) feeler gauge installed between stop screw and lever. (3) Throttle valve at idle position. (4) Throttle valve at fully open position. (5) With .014" (.35 mm) feeler gauge installed between stop screw and lever. (6) Terminal E2 is the top terminal (Brown wire). IDL terminal is second terminal (Blue wire) from top of TPS. (7) With .023" (.58 mm) feeler gauge installed between stop screw and lever. (8) Sensor is nonadjustable. Apply 5 volts to Blue/Orange wire terminal. With Black/White wire grounded, voltage at idle should be less than 1.25 volts at Blue/Red wire; at wide open throttle, approximately 5 volts. (9) With .022" (.56 mm) feeler gauge installed between stop screw and lever. (10) - To position throttle valve at idle, apply approximately 18 in. Hg vacuum to throttle opener valve.
