today after driving my 90 to work and back and about 30+ miles to get the exhaust leak fixed, the ignition coil totally failed on my while driving.
The truck cut out and would sporadically try to restart and then die..
it seemed like it was out of fuel (gauge read 1/2 tank), and just cranked..
trouble shooting included changing the following items on the road side
computer and fuel pump relays
add 2 Gals of gas,
now.. it got serious
change Ignition amp module back to the old known good one
and finally i changed back to the old known coil
and voila back in business
after each step i retested (tried to start it) and nothing was working until i did the coil.
that sucked.. but with some help from derek for the gas and the socket its back and running great.
moral to the story..
Don't buy cheap coils
carry some spares
and have tools (i learned this one today, i usually have them)
here is the culprit...
