Hello there, thank you for asking about your 1991 Geo Storm. After your comment about flooding the parking lot with steam, this symptom leads me to believe you may have a failed head gasket. A failure in this seal will...

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...

Hello. A no start, click sound condition like the one you describe, is usually caused by a low battery. It may be possible that your battery has enough power to run your accessories, but not enough to start the engine....

The battery may be bad to the point it cannot operate the starter but had enough power to run the radio or lights. The starter will need about 100 to 200 amps to turn it properly, but a radio or...

Without knowing what piston return spring you are talking about it will be hard to come up with a diagnosis for you. If you are talking about the rear brake return spring then you may have to have the rear...

The crankshaft sensor is located on bottom right fron of motor near crankshaft pulley.

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...

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....

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. 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...

A number of things can cause a crank / no start condition. First, you must check for the basics. Is the engine getting fuel? If not, the problem could be a bad fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement) and/or bad fuel pressure regulator...

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...

It is possible this is caused by some dirt, grit, or other bit of trash in the valve body of the transmission. The valve body takes the mechanical selection of "Reverse" from the gear selector, and turns that into the...

Coolant leaks will only get worse over time. Generally, when coolant is leaking there will be a white residue at/or near the leak source. The best way to locate a leak that may not have an obvious source is performing...

Just by pouring Coke on cables do not clean the cables enough to get good voltage to the starter. I suggest you have the cables and clamps cleaned properly and if still will not crank then have the new battery...

If you have a faulty alternator and the vehicle battery gets low on voltage then the computer may not shift the transmission gears correctly and cause other drive symptoms like stalling or surges and rough shifts. Engine and transmission may...

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 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...

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 (https://www.yourmechanic.com/article/does-an-automatic-transmission-have-a-clutch) correctly. Check for...

This may cause other engine problems relating to the engine not warming up properly to run at normal operating temperature. There are many other systems that run based upon engine temperature and coolant temperature. Fuel injection and timing for example,...
