The fuel gauge shows empty with a full tank of gas and I cannot tell when I am out of gas.

Put in delco iridium plugs car was missing times 2 days noticed oil in one housing and signs in another housing.Mechanic can't repair till this weekend.How much damage is this going to cause!Car was running great till then.130000 miles Now have flasing check engine light!

my 2004 chevy trailblazer was leaking coolant so I figured since I had a big hole in the top of my resivoir that it needed to be changed so I bought a new one and got it put in but its still leaking from the same spot(the back, there is a hose in the back of the resivoir) I don't know what IS causing it. the old one was not hooked to anything so I didn't hook this one up to anything. any suggestions????? it happens all the time, it don't matter if the truck is running or not it still drips out.

I have replaced the plugs, fuel, and air filter. also fan clutch and water pump. it shows code p1481,1482, and 1484 on my little hand scanner. I talked with a tech who said that the 4.2L have a secondary air on the side of the block that may cause it but idk. If i clear the light it stays off for 10-15 miles then comes back on and the cruise cuts out. plz help

What to do my battery is new don't want to drain it.

Fully charged. Wont turn over. Just dims the lights wen u turn it over. Starter is getting power, it turns over wen i start it from the cylinder. But not getting fuel or fire. Just cranking over dry. Im thinking its the anti theft. Is this common in these vehicals? I tried dicoing the bat, connecting it. Then waiting half hr. still nuthing.wats your thoughts?

I have an engine error code P0410. The air pump does not come on when engine is started. The 60 amp fuse in the engine fuse box was blown. The pump and hoses were filled with water. I replaced the fuse and the check valve on the manifold. I figured this was faulty which caused the water in the hoses and pump. I removed the plug from the pump and checked for 12 volts after the engine was started. No voltage was present. I removed the relay from the pump and disconnected the plug. I measured 12 volts across the coil. Figured the relay was bad and replaced it. Still no 12 volts at the pump connector. Could use any help from here.

I'm guessing the brakes need to be replaced.

thank you

when you push on the horn inside the car it does not sound but when you hit the lock button on the twice it will sound. Thanks

my a/c only works on 4 now and the miles show up in odometor but not sppedometor. ck engine light, airbag light and change oil light always on.

I have a chevrolet captiva 2009 2.0, and a warning light started to flash yesterday. It is in the same cluster as the parking brake, glow plug, & tailgate open. It has the same coil symbol as the glowplug but with dots underneath it. I cannot find anywhere what this means. I have driven my car today, and after 2 miles the light went off.

The gas gauge went out in 2008, my brother was terminal and I had no way of getting it fixed. I am on a fixed income and it is still hard to come up with the money for this. What are we suppose to do when it is GM's fault.

the dealer said it may just need oil changed or more coolant that service engine does not mean to replace the thermostat they said it takes a 10,000 dollar machine to read it properly not the one at the auto parts store.

???? any ideas on this issue.

Need help my 2003 trailblazer tries to die when I turn the A/C on anybody have a clue what could be wrong. My husband and Charlie are stumped they replaced plugs and drained gas tank found water in my gas in a quart jar 1 inch on top was gas the rest water I am goin to contact Shell station on that I am mad I paid 3.75 a gallon for water. Plus Bobby replaced a cylinder. 70 dollars later and it still not running right. Any help welcome.

I replaced the coolant temp sensor. I am still getting a PO128 code. I tested the sensor and it tests good. The gauge reads 200. What else could be causing the code?

I've changed the coolant temp sensor 3 times. What else could be the problem?

I have 2 lights that are coming on they look like the traction control symbol but one is in a triangle and the other has a wrench beside it

what do I check next?

It stuck on 20* when it's 50* outside, any help would be appreciated.This problem started yesterday.Auto Temp control 4.2 L.

Thank You

Then it pops on also I believe the code means low voltage to the sensor. Has 56,000 miles does it just need a new MAP sensor? Or is the connection bad.When light comes on I do not notice any difference,except mileage could be better. Which if I understand right a bad MAP sensor will cause poor mileage.

what does code po269 mean

Code reader says MAP low voltage. Wheres MAP located on 2007 Trailblazer 4.2 L engine. I reset code might drive few hundred miles before comes again same code P0107.
Any one have a clue whats going on? Mileage 55,063.

how do i check the transfer case module

going down the road the rpm gauge go up and down motor runs rough. if the eninge stays below 2000 rmp works fine, I'm thinking it might be the cam or crank senor. it has 178000. am i in the wright area or may it be something elso.

just bought vehicle. only buttons 1, 2 are illuminating at dark, along with only one side of the temperature slide for vents. Nothing in manual about illumination. Hard to see them at night.

I was told thay my front wheelbearing needed replaced and now it snowed I tried my fourwheel drive and the noise was worse and I dont think it kicked in to fourwheel drive is that possible

We have a 2005 Chevy Trailblazer that has recently been having an intermittent starting issue. We have replaced the battery, ignition switch, starter relay and had the starter tested - it's good. So we are not sure what to do. The car may start for several days and then you go to start it and all the lights come on and the accessories work, but it won't start. After lots of tries it may start and it may not. We would appreciate any help and advice.

Thank you!!!

When Heat turned on in floor or defrost mode, loud knocking from under center of dash. Vent mode is quiet. When I press the re-circ button, it flashes for a second or two, but never turns on... Would this be an accuator? what would I be looking at to fix or have fixed? THANKS!!!

Those are the codes on the car I need some help please.
Thank you

the tube for the air filter box came loose and got wedged to where it was being chewed up by the fan.
