Hello last week my front suspension is sitting very high. The rear seems to be no issue.

The pump runs for a long time and sits very hight. Making the ride stiff.

Looking for help!

 

If it's just the front height that is maxing out I would look at the front ride height sensor first. Could be the bracket is bent, damaged or the connection is to the sensor is loose or corroded. Has there been any work done on the car lately?

If not, one thing you can try if the sensor and bracket seem ok is to loosen the air hoses to each of the front air springs while the car is off. Once the air is out tighten the hoses and start the car. Leave in park while the compressor runs to inflate. If the front has not inflated to proper height turn the car off for a minute to let the compressor cool and then restart letting the compressor run again. Repeat if necessary.

However a code reader that can read chassis and body codes may eliminate much guesswork. Other related components could be a faulty ASM or leaky valve block in the trunk. Driving the car with the air springs inflated like that could cause the air bladders to explode. Depending on their age etc. there's is a good chance they could explode in the driveway.
