I've replaced about everything on this car and still no fire any suggestions?

 

What's everything? That does not tell us much.

 

all the coils plugs and sensors then went deeper and did the timing due to a backfire issue but after all this still no spark.

update: when I did all of that the car turns over but wont crank. Im doing a ground wire tonight.

 

have you checked for power to ignition, coils and such. download factory manual and go through the no start process.

 

go here for 99svc manual. https://www.mediafire.com/?40mfgeoe4ctti

 

i downloaded that thank you.

 

What timing did you do on this direct ignition system? Did you have all the plug wires off at the same time? A engine with no spark can not back fire.

 

I did the timing according to the manual.

 

There is something I am missing. Timing in a 3800 is not adjustable do you mean you checked the firing order?
