my car wont start i thought it was the dis. cap i bought a new one but it wont start and now when i turn it the lights inside the car turn off and back on and its slow turning and whens its turning the check light is on but dim same with the other lights and the rpm gauge goes up and down and the heat gauge goes up slowly but i stop turning it all the gauges goes down it didnt even heat up

 

Is it cranking but just not firing up? Check your relays. If you just aren't getting much juice to crank her over, check your terminals.

 

checked all of that even got a new cap for dizzy and new plugs and new wires but now start it started before it stumbled on accel but went fine up the road then just cut off after like a mile and wouldnt start it turns slow to

 

fuel pump could be bad, how old is it and can you hear it running? Fuel filter clean? Is everything grounded? wires and plugs are on secure? Go to ask.com and you will be able to narrow everything down and eliminate certain things. Anything I couldn't figure out on my own I could figure out from that website and I mean EVERYTHING. Also, get a voltmeter and check your wiring and your fuel pump relay good.

 

trust me dude fuel pump anit going to be bad its 20 years old to 88' but its looks like power is lost somewhere like it getting power cause when i try to turn it everything goes dim

 

as I said, get a voltmeter and check all of your wiring. There are a 100 things it could be and the things I am telling you to check are the basic things to check when the car won't start. Check your grounds to make sure they are good and make sure everything is connected. If you don't have a voltmeter, I have one you can use. It seriously sounds like a bad connection somewhere because the lights are fine when key is in acc and then dies when you turn it over? I didn't catch that in your original post, I thought you said she just died down on you and now won't fire up.

 

i think the alternator is broke or something is not conectted

 

sounds like a bad ground. check ground from tranny to frame, vc to frame starter, and batt.

 

Are you saying it has a weak cranking? How old is the battery?

 

it might be a ground cause the battery is only 3 weeks old
