1994 Buick Lesabre Repair Question
Car won't start at all now.
I replaced the wires, plugs, MAF sensor, and now I just finished the crank sensor. It just won't start. Before it would start after a very prolonged, 9+ times trying to get it to run. The starter works, the battery is charged, I can hear the fuel pump running, and I get 41psi at the rail, thanks to the fuel pressure tester.
What could be wrong here? I just completed the Crankshaft Position Sensor on a hunch after reading of similar problems, and cleaned the crankshaft pulley so that the magnetic pickup would be perfect. I really can't think of what else to do here?

Are you getting sparks at the plugs?
Well the starter works, let me check.
Yeah I've got spark. It sorta starts slightly, but doesn't stay on.
You have been replacing a lot of things by hearsay, that is costly and a waste of money. You need to diagnose what is missing causing the non starting.
Have you checked for trouble codes?
If the sparks are not bright blue, it can mean a failing ignition coil.
The car actually does start, but then quits one second later.
How can you tell if the sparks are bright blue? I took one of the plug wires off the car, put a spark plug in, and grounded it, but it gave off an orange spark. I don't know if that's really the correct way of doing it.
There was a trouble code, but unfortunately in doing up the Crank position sensor I d/c the battery and lost it. I'm getting sparks from all the nodes of the coil pack when I test them.
Yes, you can do it that way and orange means a weak spark.
Dang, a weak spark huh. So a coil pack is in my future then?
I know there are 3 separate modules on this car, if it's all of them, could it be something else?
