Car's service engine light started flashing, car died. Tries to start but cant. Changed spark plugs (not wires), now when I reconnected the battery (good) I can't even get the car to try and start. Is there a firing order for the wires on a 2001 Chevy Tahoe? I did not do one at a time and may have mixed up wires, but do not see on the 2001 that it would matter. If does matter, how do I find the correct order?

What is the litre size of your engine? The above picture is for 5.0--5.7--7.4 18436572.

Are you saying, it won't even crank, now? Or it cranks good but won't start?

Thank you. It will not even start now (NO power in car at all now), before I changed the plugs it would try to start and no probs with power. 5.3 engine. When I changed the plugs like I said I may not have put in same original place, but don't see that it matters on my 2001. Am I wrong?
By the way I got a P0300 error that is why I started with plugs (had never been changed before).
Thanks again

this for the 5.3. With coil on plug ignition, it does make a difference which connector goes on which plug. If your saying the starter won't even crank, maybe you run the battery down?
