Question about 1986 Chevrolet Celebrity

1 Answer

No spark to the spark plugs

I was driving down the interstate and the car went dead like you turned off a switch. the coil has 12v. power to it on a two prong plug. is the other wire the ground wire and should it have continuity to ground? The coil has another two prong plug that goes to the distributor which I assume is the power for the distributor. I know the coil is good because I put a new one on it after the car died. I tested 3 coils and they all read the same. The old one, the new one and another one I got from the salvage yard. I pulled the distributor to check the pick-up coil and it is good.I have 3 different ignition modules and they all read different. If I don't have a ground at the coil isn't that my problem?

First thing to do is change the cap and the rotor in the distributor.They can cause the car to just die like tha tbecause the rotor can burn through or the carbon button in the cap can wear away. Both these can cause the spark to go directly to ground.The ignition module or pickup in the distributor could also be the cause.Very common failure items in older GM's.

"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

Not getting fire from coil on 2006 suzuki frenza

it has 2 internal , wasted spark coils.
there is not one coil, but looks like 1 large pack but is really not.
it has 2 coils inside , 1 running 1and 4 and one running 2 and 3 spark plugs.
so are all 4 failing
and did you use the correct test, for wasted spark. in that
you must test 1 and 4 at once? and 2 and 3 at same time.
did you?
the fuel pump relay sends 12v to power the coil pack.
so if that is dead, so will all spark all 4 sparkplugs.
repost stating if you have 1 or All spark dead.

2006 Suzuki forenza no fire from coil pack

what country? this is the WWW, post country for better answers.......!
Only a scope can see the fast 5mS signals to the coil.
so its either the coil pack or the ECU blown. (wires are always suspect)
you never said , all 4 are dead, or 1 or 2, and how many packs.
some non usa cars have wasted (2pak) spark , not 4 COPS.
state what cylinders have spark and which don't.
there are only 2 ways to fix cars.
1: guess and swap parts
2: use tools. my guess is you dont have them.
some coil packs are active (ignitor inside) others just a coil.
you can test the restance of the coils, with a DMM , ohm meter.
if active you cant.
the fsm covers this on all cars.
the 2006 Forenza as delivered to USA has.....
has a large single, dual wasted spark coil pack. (brick)
it does in fact have , internal ignitor drivers. inside. so can not be tested
with and ohm meter on the primary side. but can be on the secondary
you do know how to test wasted spark , right, All spark plugs must be
attached and grounded for the coil to work,
1and 4 are shared.
2 and 3 are shared.
so to test , you must keep the spark plugs (both or all 4 is best)
attached and the shells of spark plugs grounded.
there is a fuse that powers the coil pack. (usa)
the fuel pump relay sends power to the coil pack.
so of that is dead,so will be the pack. (im reading FSM as it type)
get an FSM.
pin 2 on coil pack is power. 12v.
pin 1,is spark 1&4 drive (fast ECU pulse)
pin 3 is 2&3 coil drive. (scope can see it)

recap, are you using the correct wasted spark testing method.
and are all 4 spark plugs dead.?

Where is the emergency shut off in a 1995 geo prizm?

All cars, EFI. (some have 3 fuse to operate ECU/spark/ fuel) check em yet?
check power to pump 12v cranking?
no, ? 12v, or 6v? (6v or near is corroded wires /conns)
check power (12v) from fuel pump relay cranking, got 12v there.
if yes , the the path is broken to the rear ) (inertial switch?, not in 95)
if not,12v now, the FP relay is bad or ECU is not turning it on.
if 12v is across the FP relay coil the ECU is working.
if 12v is across this relay, and output is dead, that is a bad relay
or the FI use feeding it is blown.
btw #1 all cars cut fuel (INJ) when spark is detected bad. (ecu)
btw#2 some (software) cut the fuel pump for same reasons.
btw#3, most cars, only activate the FP relay for 3 seconds key on, each time. and some cars only cranking, and running.
all these facts, need to be known to make progress, in EFI.
and more.

Car went totally dead, while driving. check spark plugs, there no spark at all. replaced, coil, crank sens, cam sens. still no spark

did you check all fuses with test light, find out if that vehicle has a fuel shut off switch, call dealer. Check those relays and ecm fuses

Coil is not firing after engine over-heating

Check all of your fuses and all of the connectors at and near the distributor/coil.
