Re: 1993 buick le sabre no spark problem
You should be hable to get some free repair tips at autozone.com, or buy it, but i will recomend you to replace the crankshaft sensor, because the crank sensor and the ignition module is what trigers the coils, i hope and i been help full and i will apreciate the ranking to me.

do you mean it will not turn over or it turns over but will not start..?? If it turns over it is possibly the IGN module ... expensive part.. could be the ign switch.. inside the steering column.
Have you checked to see if spark or fuel is missing? one of these has to be missing for the engine not to start if it turns over.. If it does not turn over check the starter for "heat Soak" an old GM problem.
Unscrew the ignition coil(s) from on top of the module...(leave plug wires attached)....and set aside noting coil position on module....unplug module and replace with a known working module.If there is grease under old module...transfer it to new module.Replace coil(s) and start her up. TIP. While you are there,why not also change the crank sensor (if it not new).....it is THE trouble maker on these engines.
these cars have a antitheft system that will shut down fuel and crank. be sure to check to see if after the car ignition is on for 30 seconds and look to see if there is a security light on in the dash. if so then turn to crank if security light flashes your problem is that the chip in your key is not being transfered to the security module, so starter will not work. you will have to replace the pickup in the cylinder or bypass the security with proper resister
does it start up and die again real quick and can you keep it going with your foot on the gas. if it does and you can it is probably the idle air control valve or the throttle position sensor. if it doesn't and it just turns over try the ignition control module. my 94 park ave did something similar but it shut down and wouldn't start back period and then i cleaned the chip on the key and it fired right up.
thats weird mmmm make sure than you have power going to the black and pink wire or pink with black stripe wire when you turn the ignition on, i don't know what else to recomend you since im not close to the car but the only coming problems on these cars is the module or the crank sensor, did the module installed on it was new? or used? if not sure or even if is new call to auto zone
and ask them if they test ignition modules for free i belive they do and if tehy do take the module out and take it to them, for testing, also by the time you remove the igniton coils turn the ignition on, and make sure you are geting power to one of the coil conectors, and the only way to get to the conectors is by removing the coils, and if there is not power then your ignition switch or a lecttrical problem is present, also make sure to do a cotinuity test to the wires coming from crank sensor to ignition module, check them for open or short to ground
