Engine will not start

Three days ago, we were driving about 30 mph, the car just stopped, It acted like it wanted to start but wouldnt. We had it towed home, I replaced the fuel pump, still did the same thing, then I had a mechnic look at it and the timing belt came off in his hands. We re placed that. Last night we went to the store. Drove fine. This morning I went to start it and it is doing the same thing acting like it will turn over but wont start.I opened the radiator, it was almost empty filled it with water and still wont start can anyone out there please help?

Thank you for contacting me, I have not checked thos things as of yet but will can it be anything else?Possibly timing belt jumped time?Not tight enough?Or bad waterpump?How do I know if waterpump is bad?

I have a light inside on mydash flashing and it says hold what is that, its not the gear shif button so what else can it be?

We started having trouble with battery, had to jump it to start it after setting for more than a couple of hours. Went to the store and car would not shut off even with the key out. Drove it back home and still would not shut off. Pulled the fuse for the main computer and car shut off. Put the fuse back in and the car would not start at all. Nothing
Took the battery to the parts store and it was dead. Bought a new battery and put it in and car still will not start. We have power and lights and dings. But nothing when we turn the key
then when we take the key out it starts clicking and all the dash lights come on. We have to disconnect the battery to get this to stop. It dose not start this until we connect the battery and turn the key and take it out.
One more note to concider is there is an after market security system on the car with remote start
it is a viper 550. We haven't used the remote start in over 5 yrs. And we stopped using the security system because the doors locks sometimes stick
Please help us

I just got my car back from an accident. It was running hot for a few days so I put antofreeze in it. It was fine after that. I was driving down th road and al of a sudden I was pressing o the gas and it just would not go an faster. Finally the whoe car just cut off. My radio was still on because its connected straight to the battery so I know its not my battery. I tried to start it back up and it was kinda turning over but wouldnt start up. I dunno if its my starter. Or my feul pump. Can you help me?

I have a kia sportage that will not keep communication with my scanner. When you first connect it, it will read, but after you try to start the engine it keeps flashing between no communicaion and collecting data. I went and bought a used computer and installed it but still the problem continues. What should I do?

My antifreeze bubbled out my car now it won't start?
