Question about 2004 Chevrolet Cavalier

5 Answers

2004 chevy cavalier wont start.

I have a 2004 chevy cavalier with a 2.2l ecotec engine. The other day I performed a brake job. Before the brake job the car was running ok with the only code showing up being a misfire in cylinder 2 due to a bent plug point. After the job the car suddenly wouldnt start. the fuel pump is turning on and I can hear the whinning. The car is either not getting a spark or fuel and I cant ground a plug to check for a spark because the ecotec uses plug botts not wires. Does anyone know why this might be happening and what I can do to diagnose the problem? Thanks a lot!

Just change the pads or did you mess with the master cylinder?
I think there is a vacuum hose that runs from the intake manifold to the brake booster (big round thing the master cylinder mounts on). If that line is off, that vacuum leak may cause your timing not to advance and the car not to start.
Only thing related I can think of.
Unrelated, notoriously bad fuel pump. If you have a non OEM gas cap try taking your gas cap off. Turn the key to on and see if you can hear the fuel pump in the gas tank. Remove a fuel connection to verify you are getting gas.

How do I turn off my service, abs, and trac off lights off and why would they be on? I have a 2004 Chevy Cavalier with the 2.2 Ecotec engine


Service light can be turned if with an OBII scanner (Autozone or any good parts store can reset service light for FREE) The ABS & trace control lights are in because you have a wheel sensor(s) that are bad - replace bad sensor and then a certified shop or dealer has to reset ABS light (EXPENSIVE TOOL)

Need to see a picture of a 2003 Cavaliers engine. To check out what looks like a missing hose.


Yes its a Ecotec then all you have to do is go to a dealership and pop the hood on a Chevy Cobalt or google images of 2.2l ecotec engines they are popular enough to have a large aftermarket following so there should be plenty of pics

There are several engines that will fit the 2.2l Ecotec, 2.4L high out put motor, and I have actually seen a chevy cavalier that has a 3800 V6 in it if you want to go all out but in most cases sticking with the ecotec motor or the 2.4 High Out Put motor would be best they are two of the best motors for these cars and since the Sunfire is basically the same car as the cavalier almost any thing motor wise is inner change able between cars depending on the motors i own an 2004 chevy cavalier LS sport and a buddy of myn has a 2004 Pontiac Sunfire and both have the 2.2L Ecotec and are both Manual trans and even most of the interior parts are the same except for some of the dash board components hope this helps you out
