2003 Honda Civic ex

Honda will not start. Replaced Cam and Crank shaft sensors, ignition coils, spark plugs, Main relays behind glove box, It cranks but there is no fire. Timing is set, no noise or sense of being stuck when cranking by hand. what else could it be?

Vehicle had over heated, so I bought it off the owner, come to find out they had put diesel fuel in it and drove about 60 miles before it overheated. fuel tank has been cleaned, pump still works, injectors work… all cleaned.. gas is flowing..

  1. Is there any check engine light codes?

    Does it have anti-theft or aftermarket security system?

    Does it have injector pulse? No fire or injector pulse (and a good fuse) would indicate a faulty ECM
    Have you checked the ECM fuse?

    Have you performed a compression test? (this would rule out the possibility of a broken timing belt)

  2. the only code that showed was P0113 sensor one circuit high in put.
    I believe it has anti theft, but not after market. I’ll look into it. I just bought this car off a tourist that broke down traveling from Missouri to California, they didn’t want to deal with fixing it so they just sold it. I have not checked the ECM fuse.. is that located around the same area the Fuel pump relay was at, behind the glove box?
    The injectors are spraying fuel, all four when tested.
    Have not performed a compression test yet.

  3. The fuse should be located in that same fuse block.

    P0113 Honda – Intake Air Temperature Sensor Circuit High Voltage

    Possible causes
    – Faulty Intake Air Temperature (IAT) sensor
    – Dirty air filter
    – Intake Air Temperature (IAT) sensor harness is open or shorted
    – Intake Air Temperature (IAT) sensor circuit poor electrical connection

    The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.
