1998 Buick Lesabre How do you test the coil packs?

cranks fast? and battery fully charged is the WAY!
Getting gas means, what? how done, ? the dribble test?
FIRE,, what is fire, spark good on all cylinders? tested.
FIre takes 3 things,good compression ,spark then fuel
or no Combustion FIRE.3 things.
no engine told and is an engine question, 3.0L or3.8L?
3.8L V6 I guess and answer now. has 3 sets of dual spark coil packs
that must never be wired up (HV) wrong as many do.
new wire sets plugs are best never this old ever.

push rod valves, cam in block.
connected new battery up backwards or charger up backwards, blows up very expensive electronics.
here is the otto cycle tests, (technolgy)
engine good, compression 150psi up and near equal all.
spark good to all cylinders, tested good.
if get this far, test fuel works for 3 seconds or more.(spray starter)
fuel is last.
3.8L (VIN L, 1 And K) Engine code not told or RPO list 3.8L (VIN B and 3) Engines Firing Order:
the coil wiring is not the same on both engines.
no VIN told
vin B or 3 here
rule 1 replace parts 1 by 1, never in pairs or more or get lost and need this drawing or t he L,1,k) drawing cure that.
test spark 1 by 1. there are 3 coils , firing in wasted spark MODE.

COULD BE MODULE I HAD THIS PROBLEM.

if it shows a fault like this then its a new coil pack

IF SPARK PLUGS AND WIRES IS GOOD.I AM LOOKING AT FAULTY COIL OR BAD IGNITION MODULE.

The problem is the crankshaft sensor for sure. It is mounted behind the crankshaft pulley which is pretty difficult to get off as you need a special puller. A shop should charge about 1.5 hours for this job. It is a very common problem.

This is the Whole Set up Coil Pack numbered on coil IF OE
I Hope this Helps and if so PLEASE RATE ME Accordingly
Thank You Very Much

Do you have check engine light on???if so scan it OBD 2 yue$$ding isn't the way to go,if you don't have a check engine light on then perhaps coil pack!!! coils do run intermittent some times! and not trip the eng light on !!!!this would be a great place to start.Hope this helps

they can test your ECM (under the coil pack) at your local parts store

you can take them off and have them tested or you can pull the plugs and there should be two plugs that will be really black follow those wires back to the coil that is bad. or you could also have someone crank it while you stick a screwdriver in the end of the wire on the plug and hold the screwdriver next to the engine or a good ground and there should be a bright blue spark but be careful and dont touch the car or it might tickle a little bit

no they fire off individual coil packs one could be bad and not letting it start
