Difficulty: Easy
Instructions
-
Step 1
Narrow down the problem. Is the car not starting? Running roughly? Conking out? Using too much gas?
-
Step 2
Isolate the system most likely to cause that particular problem. If the car is conking out, the fuel system might be at fault. If it is not starting, look at the electrical system. Check the cooling system if the car is overheating.
-
Step 3
When you have isolated the most likely system, locate the weakest link in that system. The fuel pump, for example, is often the most vulnerable part of the fuel system.
-
Step 4
Check each successive part in the system until you find the problem.
-
Step 5
Replace or repair the broken part.

on 8/31/2009 I have a 2000 Bravada SUV. It was running good and then just wouldn't start one day. I replaced the fuel pump and the ignition modulator but it still won't fire. What could my problem be?

on 6/20/2009 I Have a 2002 Hyundai Elantra Ve 4Door 4 cyl 2.0L Automatic I have a Problem with the motor. I think. When I stop the car and I let it sit for about 4 to 5 hours and I start it back up and I put it in drive the car wont move the RPM’s don’t move. And when it goes into 2nd gear the RPM’s rev right out and then it shifts. I don’t want the motor to go right now and I can’t afford a new one. anyone with suggestions e-mail me at cracker_43@hotmail.com
