Question about 1991 Cadillac DeVille

1 Answer

The car just stops and may or maynot start again.

The car has just had the alternator replaced, a new battery, and a water pump. Now the car will start fine and then while you are driving it may cut off and will not restart. This morning I went to put gas in the car and it would not start back up. Also, it will cut off randomly and then if it does start back up, it seems to not be getting any power. I have had it looked at and after towing it to the shop, it starts up fine and will run for 30 minutes or longer fine at the shop. The car has 120,000 miles and is just eating my money and no one can figure out what the problem is. I don't want to pay $500.00 for a new fuel pump when no one can diagnose the problem accurately.

Where do you live?
That sounds like a fuel pump.
Why can't anyone diagnose that?
I assume they checked fuel pressure,filter and road tested it.
How many people or hours were put into the diagnostic process.
Why don't you pull the fuel tank yourself,and change the pump. You would save money and it would be done correctly?
There should be a fuel pump relay in the system.
Are you sure this isn't more about the money than the fix?
Very seldom does an Alternator and Battery go at once.
You need to pay attention to what your being pitched. Find a good shop

the alternator runs on bushes pushed by springs a new regulator that has new bushes and springs should fix it as long as the armature isn't damaged i would ask the auto elec how much for a reconditioned alternator or if you don't trust auto elec try another auto elec, if they doth say same thing, they are right, your loyalty to your mechanic has cost you a small fortune already .auto electricians have more advanced tools for testing , hope this helps

What could be wrong with my 99 Mazda Protege now? 5 months ago it overheated, replace alternator and belt, now battery wont hold charge and is overheating again, and loosing water coolant.


For a coolant leak you need to check all the hoses and fittings by radiator, heater core, expansion tank for leaks and/or integrity. Also make sure that your water pump is not leaking along with radiator cap and thermostat body. Overheat condition has no effect on battery - if it does not hld charge it is because it is chemically worn out and needs replacement. Until you correct water loss, have extra water in car at all times and run your heater full blast - windows open!!!!

What's the difference between fuel pump & replacement fuel pump


I dont think you have a fuel pump problem, It sounds to me like you have an alternator problem. You see when your alternator quits working the car will run on your battery juice untill it is out of juice and all electrical will go out when you put a new battery on it it will start working again untill the new battery is out of juice or untill the alternator is replaced. If the vehicle wont run then the fuel pump might have went bad too. I hope that helps you out.
