My car turned off of me while driving in the middle of the highway. Right before I got on the highway, the radio started to turn off and on. When I got on the highway, after reaching sixty mph, the lights on the dashboard got very bright, the high beams went on, the horn honked, and then the car completely shut off. I changed the battery since I saw it was leaking some water, mind you the batter is less than a year old but was under warranty so I was able to swap it out for free. The old battery was at fifty percent so the car apparently would not with that low of a charge. After changing the battery, the car still does not start. It cranks, but the engine does not start. My friend tests the spark plugs and there is no spark coming from them. Help!

Hello,

It sounds like the alternator is over charging the system and has blown out some stuff.

Here is a guide to test the alternator once the car is running again.

It sounds like we need to run the codes to have an idea on where to look next.

Most likely it is the crankshaft angle sensor that is causing the problem. This guide will give you an idea on what you are in for when changing it. There is a diagram on how to do it on your car (below)

Here is a generic guide that will help as well.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken

Hi Ken, so if I'm reading this correctly, you're stating a bad alternator over charged the car system and blew some stuff out, like the crankshaft angle sensor? If the crankshaft angle sensor goes bad, it prevents it from the vehicle to start? After further troubleshooting, I was able to rule out the distributor going bad since it turns when I crank the car. The issue I am finding is that the fuel pump does not turn on when I put the ignition key in the on position. So something is preventing the fuel pump from turning on. Also, I have a few fuses and relays that were blown out after the car died on me such as the air bag, windshield wipers, fan relay, etc. But any of the fuses that are related to the starter, eng, or any other mechanical part is fine.

Yes, I am thinking the alternator could have caused this problem, I would disconnect the wires from it until you get the engine running so you can test it. Here is a wiring diagram of the engine and fuel system so you can test all fuses and the fuel pump relay.

Please run some tests and get back to us so we can continue helping you.

Cheers, Ken
