    I'll clean the TB too.

    could my issue be related to the crank sensor behind the balancer? please say no!

    to check for spark you can pull and prop a plug wire over the coil terminal, a big blue spark will jump to the wire if its got spark.

    the fuel rail has a black cap on it, take it off theres a valve inside looks like a tir valve stem. push the pin, gas should fly out with lots of pressure, turn key to run, then test. watch your eyes, fuel can fly if your pressure is good. i lay a rag over it, it still flys.

    ill try both of these tonight. spark would tell me that the crank sensor and ICM are good. ill check the pressure at that schrader valve too.
