no spark! 87 4kq

[Ben Swann]

Shawn,

Have you checked the Hall Distributor is getting power and operating properly - output in window near 0V and output with window closed near 4.5 V.  Check as per Bently.

If no hall trigger then no spark and no Fuel pump as this primary triggers the F.P. relay as well.

I have never had a coil actually fail on the many 4kq's and similar engines like it.  I have had the Transistor/spark amplifier fail, although only once.  Hall rarely, but more likely, as the wires sometimes can evern get cut by the wheel due to internal design, and sometimes the connector is flaky or not even connected fimly.

ARGH..if its not one thing....after dropping $50 at our FLAP for a new
fuel pump relay, tried to crank the car, it caught then died...and
never caught again...we thinks it to be a dead coil...whats the method
to be sure and what else should I check? We pulled a plug, grounded it
out and still no spark.Using an OHM meter we saw the coil had power
with the ignition on, but when keying it to start it there was
nothing, we took this to mean dead coil and will be relacing it
soon...assuming its not 24k gold like the damn relay. Just to bring
you up to speed:
new cap,rotor,wires,fuel pump,fuel pump relay, new fuel filters,
recent plugs (4 months), we've got fuel for sure...HELP I wanna get
this car done so I can get the exhuast made and
register/inspect/emsission test it!
