    Hi, I have an issue that is hurting my brain.

    This is a 3VZE in a 1991 4runner with 250,000 miles. I changed the head gaskets, cam seals and timing belt. It ran before I started, but poorly due to the head gasket.

    After the job, it will not start. It is acting like the timing is off, with an occasional backfire through the intake which stops after a few seconds of cranking.

    I am quite sure that the crank and cam timing is right and the distributor is about to fire #1 with #1 at TDC. However, I am pretty sure that the gas fumes are starting to affect my judgement.

    I have fuel squirts at each injector and spark at each plug.

    What am I missing?

    Backfire in intake usually indicates timing is off. Make sure #1 is on compression stroke and you have jumped E1 and TE1 (check engine light will flash). This will let ignition run at base timing. Should be set at 10* BTDC.
    Timing is most likely 180 off
