Remave the battery cables from the battery and clean the connections and replace bolts. Have seen this before.

Buick Lesabre 1999 - 3800 my 1 & 4 coil pack not firing why?


i bet it is the ignition module, have it tested at oreillys or autozone, it is what the coils bolt to, common failure, or possibly a crank sensor

Identifying Ignition Types I and II

On Type I coil packs, three twin tower ignition coils are combined into a single coil pack unit.

On Type II coil packs, the coils can be replaced separately and the ignition wires are all on the same side of the coil pack.

No firing contact to the spark plugs. Have already replaced brain box, coil pack an cam and crank sensors. Any suggestions?


Two things.
1. does your car have three seperate coils ontop of a module or is it all one piece? If it is the seperate coils you might wanna change the module that they mount to.
2. If its the all in one (magnavox) coil and you are sure all the parts you replaced are in working order then you might wanna have the timing chain checked. It may have broken and if the cam isn't turning you wont get spark.

Im not geting any spark.its turning but not cranking up


it the ignition module pack or the crank sensor or the cam sensor.i beleive the packs are under the ignition coils.you can take out the ignition module and run it up to autozone for a free test.

Why is there No Spark in a 1991 Buick Lesabre after i changed the coil pack crank shaft sensor and ignition control module?


did u line the crankshaft sensor up? if not the sensor could have been damaged and the harmonic balance ,some models show a cam sensor ,check that,are u sure its not fuel related?

1992 Buick LeSabre Custom....180K on the odometer...stalls at low speeds....sometimes at highway speeds without warning...error code 17 is popular...I have a 41 also but the magnet has been missing 2 years...


dont know what the code are w/out looking them up however i do know that is a common problem when ignition coils or 1 ign coil goes bad. or distributor shaft wears out, which i dont think 92 buicks have. your 92 buick should be ign. coils . ignition coils need tested at a auto part store.most are free test call them to make sure.

Has no fire going 2 the plugs


My Bonneville 3800 did the same thing. My brother-in-law (mechanic) told me to change the coil pack module (3 coils sit on top of it). I got a module from a wrecked 3800, put it in, engine runs beautifully!
