Your ECU is playing up, probably thinking that it is stolen (security light) needs to visit a dealers computer, ring your dealer he may be able to reset for you

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

Do a bench test on the starter. Remove starter, hook up a ground cable to starter, and positive to two prongs on starter and it should spin. You can do this in vechile too but not suggested due to risk of injury. If it doesn't spin, probally a solenoid or the starter it self. Unlikely but possible.

Your key program has been reset, the dealership can reprogram your key. You can also try to unlock the door with your key when the anti theft light kicks on, try the power locks as well. You can also save money by calling a automotive locksmith, its cheaper than the dealer. Hope this helped =)

Ran out of gas, car wouldn't crank replaced fuel pump, fuel relay, and in line fuel filter and still won't crank on 2002 chevy avalanche


still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !

Have a 2002 ford Windstar just changed alternator and battery. Light on blinkers keep flashing and car won't turn over I put 5 gal. Gass in soi know it has fuel but it sounds like it don't have any


was it running before you replaced the alternator and battery or did it not run,and you thought that the battery and alternator was the cause of it not running. if a motor cranks and not start the battery and alternator are good. you need to check to see if the fuel pump is working and if you have spark
