    Cranks no start.

    Engine cranks but no start there is fuel pressure. But no spark. Replace the crankshaft sensor and the cam sensor.

    ECM issue?

    Has anyone had this problem where the tj will crank and no start there’s fuel but now spark. There are no codes. Checked voltage and grounds to the ECM there ok the one thing that not there is the negative for the shutdown relay the one from the ECM.

    ECM shut down relay

    Haven’t done anything to engine for long time. It cranks fine fuel pump works. But now spark. One of the main things I fined there is no negative from the ECM that controls the shut down relay. Also there are now codes.

    ECM shut down relay

    If the voltage’s and the grounds are good. But the negative for the shut down relay is not there does that mean the ECM is bad.

    What causes the negative pulse from the PCM not to be there?

    I will check when I get home.
