Q: How do I use the standard ignition key?

It sounds like you're having a fuel pressure issue. If you have a fuel pressure gauge, connect it to the shrader valve on the fuel line under hood and check the readings. It should be over 10psi if it has...

If you are getting the car to die going down the road, then see if you are losing spark (https://www.yourmechanic.com/article/how-to-read-your-spark-plugs-by-olivia-marsh) to the spark plugs. If so, then check the distributor to see if you are getting oil in it or...

This sounds like most likely an oil pressure sending unit problem. These vans are somewhat known for this problem. The sending unit sits down near the oil filter and will cause the gauge to read intermittently when the sending unit...

Hi there, thanks for writing in. I would suggest replacing the battery first. A battery at 10V usually means one of the cells has failed.

Hi there. First check the air filter on the engine. A dirty air filter will starve a diesel engine and prevent it from running correctly. Then check the fuel / water separator and see if there is a drain valve....

Hi There, The inconsistent throttle response you are describing sounds like you may have a faulty throttle position sensor. The throttle position sensor (https://www.yourmechanic.com/services/throttle-position-sensor-replacement) monitors the throttle position of the throttle plate inside the throttle body in relation to your...

If a mechanic has already confirmed that the alternator is functioning and the battery is "good", there are a couple possibilities to look into. First, if there is current leakage (that is, parasitic power draw or a phantom electrical load)...
