Thread: Fox Body - no start.

  1. #1

    Default Fox Body - no start.

    The computer went out on my '92 5.0L. Capacitors leaked and it started acting funny. Also the wiring harness developed an issue around the fuel pump relay. I have a completely stock engine. I installed the new Terminator X Fox body 5.0 MPFI Kit on it. It won't start after installing the new kit. I thought maybe it was the timing, so I have tried a dozen times to mess with it, still it will not start. I even installed a new distributor & TFI. I took three datalogs with the following during each. The AFR is way lean. I'm not sure what else I'm looking at that might be the issue. Injector PW seems high, but I'm not sure what it should be. Datalog 3 should be the perfect setup for it to fire, but AFR only ever gets to 16:1.

    Datalog 2: Moving distributor around.
    Datalog 3: Reset distributor to TDC, Idle Spark disabled.
    Datalog 4: Reset distributor to TDC, Idle Spark enabled.
