SOURCE: automobile engine trouble
I HAVE A 93 4.3 VORTEX AND THREE TIMES THIS TRUCK HAS DONE THIS IN 366,000 MILES
THE IGNITION MODULE LUBRICANT INSIDE THE CAP HAS DRIED OUT AND FRIED THE PART. NOW I KEEP A 1/4" LAYER OF THE SILICONE UNDER IT AND I BOUGHT ONE THE FIRST TIME WITH A LIFTIME GUARANTEE. JUST AS THE WIRES. CAN'T HURT TO GIVE IT A LOOK SEE THEY CAN TEST THE MODULE IN THE PARTS STORE

There's two possibilities. No spark, or no fuel getting to cylinders.
I would change the plugs regardless. If you haven't driven it in a year and it was parked with fuel still in the carb. You will probably want to pull the carb and rebuild it. The old fuel is likely gummed up inside the carb.

i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.
