Okay, so I have had this car for about a week or so and a few problems have started. I have fixed most of it like my fans and coolant sensors. When I start it it would take about two tries to get it to crank, then driving home one time it stopped running completely and I turned the car off and tried turning it back on, but there were no check engine lights or anything not even the ringing for the keys in ignition. Then after I pushed it home a day later it cranked just fine. And before I was driving it was a brand new battery.

Good afternoon.

You need spark, fuel pressure and compression for the engine to run.

You need to check for spark.

Fuel pressure would be next.

Then compression. Lets see what the results are.

There is zero spark. I have tried jumping it and then my dashboard will light up and say low voltage. It does not crank at all when I try to jump it. There is no power going to the car even with the new battery. I do not know if it is a bad fuse or connection or if my computer is damaged.

Okay.

Check the cables and make sure they are clean and tight. The side mount batteries have a bolt that secures the cable to the battery. Remove the bolt and clean the cable on both sides with a wire brush.
