It's replaced and new But car won't start no more ....
So I had a problem with my reservoir tank . I found a crack on the Radiator near the cap and it splatters engine coolant everywhere on my hood . I go to pick N pull . Replace the tank and now that it's replaced my car won't start . Someone help me ..... coolant is leaking from the bottom of my car and now my car won't start . Could it possibly be Flooded ? I tried the Deflooding procedure and it still didn't work . Anyone know what could have been the problem ?

 

It's a bit hard to understand, but you have an external coolant leak and the car will also not start, correct? Does the engine turn at all but not fire, or not even turn?

Step 1 would be to figure out where that coolant is coming from. Only you can do that.
Step 2. Was the car overheated at all when thr original problem occurred?
Step 3: pull the spark plugs and see if they are wet with gas or coolant. Clean and try to start again.

 

So, it sounds like you have two problems:

1) Still leaking coolant.
You're going to have to dig around to fix this one. We can't really diagnose this over the Internet. Common problems are hose clamps not being secured (especially for the two that enter the bottom of the overflow tank), cracked overflow tank (often near the hose connections) or cracked radiator (plastic end tanks).

2) Won't start.
I assume it cranks but doesn't fire, yes?
What did you disconnect when replacing the tank? The tank itself has very little to do with suck/squeeze/bang/blow so that is unlikely to be a direct cause. Double-check connectors. Also, double-check your fuses. It's not impossible to have a fuse pop coincidentally at the same time you did the other work.
