Question

its a 94 gmc jimmy, with a fuel injection engine

Answer 1

Get a new starter. Get a good one.

Answer 2

Whithout knowing the year, make and model, the most common thing would be a bad starter.

You could also have a hydrolocked engine caused by a blown head gasket, and water in the engine cylinders.

Next time add a little more information.

Several times a day, someone asks a very similar question to your's.

It's very helpfull to include a little more information in your question to help us, help you, in your times of trouble.

Some of the simple things to include in your question is:

1) Year of car.
2) Make of the car.
3) Model of your car.
Those three things can help us narrow down known issues with particular vehicles that have certain problems that occur on a regular basis. (ie. recalls and such)

Next, If you could give a more detailed explanation of what is happening when you turn the key to start your car.
Here are some ideas:
1) Nothing happens? (dead battery?, loose battery cables, or it's not in "park" all the way.)
2) You hear a "click", but nothing else? (loose battery cables, bad starter, bad starter solenoid, or broken engine)
3) You hear the starter turning, but the engine doesn't turn? (low battery voltage, bad starter or bad ring gear on flywheel/flex plate)
4) The starter turns the engine, but the engine won't start up? (out of gas, bad fuel pump, plugged fuel filter, broken timing belt, no spark)
5) The engine turns over, but very slowly. (weak battery, worn starter, out of engine oil)
6) the engine turns, but there's an awful banging noise? (something is broken inside the engine)

Lastly:
What happened last time you drove it?

1) Drove home fine last night, just won't start today?
2) Was driving fine, and it just died on you?
3) You haven't driven it in a while. It's been parked in storage?

I like to say: "The better the question, the better the answer"

Answer 3

Probably a dead battery. Have it charged, then tested. As you should have had your starter/batt. tested before engaging in a futile repair. But what about your battery cables? And the Ford guy is right. And you can bypass that external solenoid. And have your alternator checked too. Probably OK, but most major parts stores will check it for free. Along with your battery. Best bet, borrow a battery and see if that fixes problem. Good luck taking that starter back. Most places will not accept electrical returns.

Answer 4

If a battery is very very dead it will take more than a jump start.

1 be sure cables are clean and tight.

2 if jumping have other car running and leave for 15 min before trying to start.

if that does not work take battery out of car and charge over night or get new bat

Answer 5

The hum is your fuel pump, the click may be the solenoid, so probably your starter is shot.

Answer 6

When did you last fill it with gas? Something similar happened to my husband a few months ago. Luckily we had a gallon of gas in the shed. He poured it in, and it started right up. Turns out he just wasn't paying attention that week, and let the gas run out, aargh! :P
I'm not saying it's that, but it's one thing to look at.

Answer 7

It might be the fuel pump you might have fuel frozen in the lines or the starter.

What kind of car is it and how old is the car?

Answer 8

It's probably your alternator or your starter. If your horn honks it's not your alternator... i know I'm a woman and but i do know some stuff about cars.... hope it helps....good luck.

Answer 9

starter is toast you could give the starter a couple of waps with a hammer to try to get it out of the dead spot but i would definitly replace the starter

Answer 10

you have a bad starter are you have a bad seioild check you wires from the batter to the starter
