Hi there. Sounds like the engine has either a major vacuum leak or a burned valve. Check all the vacuum lines and ports for any signs of leaks. Check the brake booster and see if it has a leaking check...
Hi there. With the limited information about your gear box (transmission), I suggest starting with checking the fluid level and color. Make sure that the fluid is full and the color is red and not dark red or black. Then...
Hello - the oil pressure sensor on your Geo is located immediately above the oil filter. It is a single-wire connector. This sensor screws into the engine block just below the oxygen sensor wiring. For assistance, I recommend an electrical...
Hi there. I'm not quite clear as to what you're referring to in regards to running HIGH. If you mean that the vehicle will accelerate slow in low gear, but runs fine once you shift into higher gears, the issue...
Hi there - first thing to check is the fluid level in the transmission. If the fluid is low (if the axles are out, is the fluid very low also?!), the transmission will not engage gears correctly. Check for problem...
Hi there. This problem might be cause by an ignition system component failure, such as a crankshaft or cam position sensor. It's also possible that a fuel system component might be the source of your issue. It's best to have...
Hello, thank you for writing in. The first thing you should do is check the battery cables. Make sure they are both clean, dry, and tight. If there is a loose connection, every time is bounces around you will lose...
Hi there. Typically when you are not getting spark at the tip of the plug wire, and nothing at the distributor, the next point to inspect would be the ignition coil - followed by the ignition relay - followed by...
Hi There, This may have caused a number of things to happen that may result in a knocking noise being generated. Generally, when a knocking sound exists from the underside of the vehicle due to some kind of impact like...
A dead battery overnight would indicate a sizeable power draw. First and simplest thing to check for is loose connections like loose battery and body grounds. Make sure the battery terminals are tight. Make sure the opposite ends of the...
If the vehicle was operating immediately prior to the repair work, and you suspect that the timing belt might be mispositioned, then yes valve timing would be the first thing to check. Once you verify the timing, if the starter...
The oil level may be low. Ensure there is enough oil. If the engine was run without oil, damage from that, in combination with other faults could be enough to keep it from starting. But, that remains to be seen....

The first thin to check is the oil and coolant in the engine to see if the engine is seized from no oil or overheating from loss of coolant. Your fuel pump in the fuel tank may have stopped pumping...
You should first check to see if the clutch master cylinder is full of fluid. If fluid is full then check to see if the clutch pedal linkage is not binding. If all this is okay then replace the clutch...
Assuming that the temperature gauge and sending unit are in good shape, what may be happening is the engine cooling thermostat may be sticking in the open position causing engine temperature to fall below normal once you are at speed....
Hi there. If the noise started shortly after the repairs you completed, it is more than likely that you have left something loose inside or an internal component is not properly aligned. However, if the repairs were completed correctly, It...
You will need to go the the reverse light sockets in the rear and with key on and parking brake applied move shifter to reverse and test the socket to see if it is getting power to the sockets. If...
