Would bad coil cause no fuel and no spark???

OK, i got the Pick up coil in and the Module is good. Now I'm not getting any spark or any Fuel to the Dern thing. I have no clue what's wrong with it. Can anyone help? The injectors still aren't finring but I know that there is good fuel pressure. VATS is disabled in the chip so I'm pretty sure that, the VATS is not the problem. ANy ideas?

NO, change your module, even if it tested good. Then fix your timeing since you messed it up when you yanked your distributor to change the pick-up, oh yeah, plug that vacume leak too.

hmm no spark at all could be because of the external mounted coil. but it should still be getting fuel. mine would fire the injectors when you rotate the distributer around...will your do that? something isnt right if you have no fuel or spark you usually have one or the other. does it crank? if it cranks pull the plug off the coil and see if it sparks...if its not sparking then thats why your not getting spark.

so youre module tested ok but a new one fixed the prob? Im having the EXACT problem you are....and am about to replace the pick up coil after the module was tested ok....perhaps i should change that too.

A bad Coil would affect spark only. I was confused on this originally but that is true. I woudl definately go for the Ign Module first.

lars...gotta say thanks man...i changed out the ignition module even though it tested good...and yep...the car fired right up...you saved me from having to take out the distributor and change the pickup coil....but ill probably cahnge that and the ignition coil whenever i get a chance...just to be safe. Thanks again man.
