won't start

[airy_m]

I have installed a new battery, new starter, and a new alternator, and still when I turn the ign. nothing happens. No click, no nothing. But as soon as I boost it with cables to any running vehicle, the car will start and run. I ran it it for 30 miles. Yet when I turn it off, it will not start again. Not even will the solonoid to the starter will click. Any suggestions.

1st suspect I would go for is that "new" alternator. I put one on one time.....and it was bad from the start. Any lights on before this happened? Bet that little yellow light was on huh?

What I would do is get the new Alt checked......the battery would have ran the vehicle for a while....but after that....would be dead as a door nail.

By the way...IF the alt is bad.....take the batt back too.....you run a batt down that low and it will never....ever be the same.

Good luck

What year is the car....miles....etc

Where are you hooking the jumper cables up?

[airy_m]

1994 grand prix 3.1. jumper cables were hooked up to 1. 1994 ford e150, 2. 2003 chevy 1/2 ton, 3. 1994 ford e150

[airy_m]

oh, by the way, the mileage is a lil above 157,000.

[ern2112]

Did you hook directly to the battery on the grand prix or the post above the fuse box?

[airy_m]

directly to batt.

[ern2112]

Do you have a volt meter?

[airy_m]

yes i do

[ern2112]

What is the voltage of the battery....have you tested it?

[airy_m]

voltage before hokking eveything up was 12.64. any way to comm. quicker?

[ern2112]

You need to check the voltage now....since it wont start at this point. I need to know if the battery has voltage. Do the lights come on? Try the headlights....and then test the voltage while they are on.....this will help diagnose the problem

[ern2112]

I gotta hit the sack...but if you will provide this info....I will get back to you tommorow.....you have a simple problem.....just need more data to break it down
