2002 cavalier won't start. 2 months ago changed the fuel pump thinking it was that.?

some more information would be helpful, however my first guess is an in line fuel filter. And if you have been buying gas at those inexpensive gas stations, crawl under the car, find the fuel filter change it to a new one then go fill your car up with chevron unleaded and drive drive drive until the tank is low, then fill it up again, here is why

el cheapo gas companies buy what is called bid gas, this is gas that is contaminated with water and tiny bits of crap. (too many particles per billion) the good companies like chevron and costco and some others, refuse to buy this from the refineries. and have placed orders with the refineries, ahead of time and ordered good gas with their own additives. And some other company bids on the contaminated fuel, it is gas, your car will run on it, but over time, hard deposits can build up, which plug up fuel filters and fuel injectors over time.

I like chevron, it has techron, which is a fuel system cleaner you can buy in any auto parts store. However, it is easier to pay a few more cents a gallon now, and keep your fuel system clean to begin with, than go back and try to clean out tine orifices that are in fuel injection systems later.

if you have a fuel pump in the gas tank, it was designed to run cooler, by being surrounded by fuel, so it is best to keep your tank full, and as an added benefit, a full tank, means less condensation (water) on the metal surfaces inside the tank, (particularly in winter) if you keep your tank mostly empty, and use inexpensive fuels, this can cause long term problems, such as excess water in the gas, and plugged fuel filters things like that which can mimic fuel pump problems.

Need more info. Does the engine turn over and not start? 1st ck to see if its delivering fuel to determine if its a fuel problem. If it isnt you can ck the in line fuel filter and all fuses. Find out if cavaliers have a fuel pump reset switch. If all thats ok follow the wire harness from the pump to where it ends and ck for damaged wires. When you turn the key to accesessary or 1st click w/out trying to start you should hear the fuel pump cycle for about 15 seconds. Hope this helps.

1) check battery

2) check fuses

3) check your gas cap is on completely

4) alternator problem

5) starter problem

6) fuel pump problem.



although if your car has driven since the fuel pump swap, chance are its not that. My first guess is the battery, and other elements of the electrical.



What sound does the car make when turning over?
Does it make any noise when you try to start it?
