Man what a hard time you have had!
\015\012Before you can trouble shoot the possible bearing problem,your engine would need to be able to run.
\015\012
\015\012Your engine will run with a bad alternator for awhile with a fully charged battery. This will allow you to have someone listen to the engine and evaluate the bearing nose.
\015\012
\015\012A bearing rattle when you rev the engine up is usually a rod bearing.
\015\012A bearing rattle when you declerate is usually a main bearing.

My car is turning over but not starting. I sprayed ether into intake and car started but didnt stay running. What should I check first? I am by myself and trying to hear fuel pump but just not sure if I am 2 seconds too late or I do not know the sound. Fuel filter looks bad from underneath but havent taken it off yet. Would the fuel relay be associated with this?


Had the same problem with my 2004 Chevy Malibu Classic which is essentially a 2003 Malibu, and as we know, I believe 1999-2003 Malibu's are essentially the same. It might not be an electrical problem or a fuel system problem. It is actually most li ... 2001 Chevrolet Malibu

About a gallon of bad gas was put in my car with barely any other gas in it. the car was running rough from start I drove less then a quarter mile and the car died at a red light and would not recrank. I changed the clogged fuel filter and put about 10 dollars of gas and fuel injector cleaner in the car with no luck..... I checked the fuses with a circuit tester and the fuel injector fuses showed nothing I changed them out even tho they did not look bad but the new fuses showed nothing on the te


First I need to know year make and model.My guess is the pump is faulty. But you would need to find out if it is getting power. And you said you checked the fuses.On most cars there is a relay that may be in the circuit before the fuse. ... Cars & Trucks

My car would not start, was cranking but not turning over. My cat converter was bad, I replaced it but now my car is running like **** and when driven my cat converter turns bright red. I replaced both O2 sensors and it stayed running but my car was still running bad. It is also throwing a multiple misfire code, so I replaced the coil pack and now my car wont start at all again. I also checked the spark plugs and they look fine...


Running extremely lean. Did you replace the 02 sensors? They detect lean and rich conditions and if the previous problem was too rich, the 02 sensors may have set ecu to run lean because of their problem. Now converters are free flowing and the s ... 2004 Chevrolet Cavalier

The check engine light would stay on and sometimes flash--the car would run badly. I replaced faulty spark plug wires and the ignition coil. Now the car runs VERY poorly and the check engine light flashes after about 20 seconds. How do I reset the ECU? Is this the problem?


The wires and coil was a just throwing parts at it ,for no reason. Try disconnecting the battery to see if the codes clear. You will need to scan for the code if it comes back and proceed with the proper diagnotics to find the issue with the engine p ... 2000 Hyundai Accent

Power transistor in distributor was checked and is ok, fuel pump was jumped and works. I don't see any bad fuses, I pulled each fuse to check. No codes are showing in memory.

Truck came in with what i thought was a bad pump(fuel) Ran on a small blast of ether. I change the pump and checked the fuses but still would not run. What else can I check?

Car was running fine, then at work, left the lights on. Dead battery, tried to jump and took awhile. Started, but ran like ****, it would idle but when you touch the excelerator it would try to die. Finally got it going but had to keep pumping the gas to keep it started. Once on the road it would run smooth. But then when you let up would try to die. Thought maybe blew a fuse but all were ok, checked for vacuum leaks or anything else that might cause. I'm totally stumped. Any help would be great

I have a 2001 Chevy Malibu that will not start . I have had a problem with the anti theft system on the car, causing the car not to start.However, I have a new problem that appears not to be related to the anti theft, but not sure. I was traveling on the interstate when the car began shaking and stopped running. It appeared at first that the fuel pump may be bad but as of now the fuel pump is not getting fire . However I have checked the relay and fuses and they are all good. What else could it


A very common problem for these vehicles is a defective ignition switch. The switch has been redesigned and seems to be a permanent fix, if attempting to replace it yourself I recommend purchasing a repair manual for your vehicle. ... 2001 Chevrolet Malibu

I bought this car and it seemed to run ok. I had to replace the oil pump seal , so I changed the timming belt. The timing belt seems to be 1/2 tooth off. I have checked it and rechecked it. Also I discovered the ISC was unpluged. I pluged it in and the car idles around 2000 rpm, and the idle speed goes up and down. With the ISC unpluged, it was throwing a ISC code, but with it pluged in ,it is only throwing a tps code I thought the Isc motor and valve were bad, but would a bad TPS cause it to i

Engine cranks fast, I do not smell gas or hear fuel pump running. Have 75,000 miles on car. I ran low on gas and refilled tank and now I have trouble starting my LS. The cars gas filter is not 5,000 miles old. Would like to know which fuses I need to check and where is the reset for the fuel pump switch? Thanks!


Usually, the reset is located in the trunk. Check the fuel pump fuse. Check the fuel pump relay if equipped. You can also turn your key to acc for 7 seconds, turn it off. Turn it on, and off. This will prime the fuel pump. If you don't hear it at all ... Lincoln LS

98 ford contour. Car sat for over a year. replaced plugs, wires, Battery, timing belt and pulleys, and fuel pump and screen, fuel filter. Car would run but wants to stall. Idles rough. Checked plugs and cyl 2 & 3 had a little oil on the plugs. I figured oil rings might be bad so I put a can of restore from walmart in it and now it doesn't even want to try to run. what is next? Any ideas?


You may have to replace plugs again, sounds like the valve seals are dried out, That along with dead gas creates a bad cycle, Make sure you fill it up with the best octane fuel you can to off set the bad gas ... 1998 Ford Contour

!987 toyota celica , wont start. So I was driving down the road and all of a sudden I stalled and could not get it going again. I thought that it would be the fuel pump, so I looked into it. It was makeing no noise, so I by passed everything and I could hear it running. I've checked all my fuses and they are all good. The car will turn over but just won't start, even with the the fuel pump running. Any ideas?


Generally it makes sense to check fuel and fire first. assuming you did not just dump some water into the gas tank you could pull a spark plug and have a compatriot turn the engine over while you hold the spark plug next to the block and see if there ... 1987 Toyota Celica
