Most likely its the OVP relay behind the battery. Could be the fuel pumps are not coming on. Maybe the tune up is so old the ignition parts are not working ie cap, rotor, plugs , coil and wires. Also check fuses for corrosion and replace with new syle copper barrel fuses.

2008 impala cranks but won't start


Theres only two possibilities why a car doesnt start...its not getting fuel or fire. Start by turning the key to the First click before trying to crank it up. Leave the key in that position and lean your ear toward the rear or the vehicle before the driverside rear tire and listen for a faint humming sound. If, you hear this sound, your getting fuel (that would be your fuel pump). That would me your not getting fire... check plugs and wires for loose fittingor cracks and replace

Car won't start 2003 Dodge Stratus sxt coupe cranks but won't start what could b the problem? I tried spraying starting fluid in the air system but it still won't start!


i would check and see if spark pluges are firing. you can take one out and plug into spark plug wire then let the bottom of the plug sit on engine and get someone to try to start while you look at the plug to see if there is any fire. if you have no fire or fuel it would be the crankshaft sencer. it could be the timing belt but the motor would sound different turning over then it used to.

Vt com turns over but dies not fire ?? Has fuel but doesnt seem to ignite ??


1) Do you have spark? Crank sensor? 2) Another quite common prob with them is the key reader. either the little metal bump on the key worn or the reader at the barel where the key makes contact but from memory if that no good it won't crank (can't remember)

GMC 2000 sierra pick up 1500 sounds like it wants to start but won't turn over. Battery sounds good so I guess battery and alternator are ok. For several years fuel gauge doesn't work and...


It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.


you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.
