I drive my van & it gets warm it stalls & doesn't start up until it sits for at least 30 mins. I stuck the two wires to get a code reading & got code 56. It says quad driver module circuit B or 2. I have replaced two solonoids in transmission & crank sensor. I am so tired of putting money in it & not receiving results. I hope someone can give me some sound advice.

Hello –

To better assist you is your model a SE or GT. Also the engine size in liter and the 8th digit of your VIN.

Have you checked the codes since you fixed the other?

Please look at the hoses connected to the Throttle Body really good and make sure they are tight and no cracks tears etc.

Next time it stalls - We need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don’t have your hands on any part of the metal!!! If there is no spark, then it is electrical.

If you are getting good spark then spray some starting fluid in the throttle body and try to start it and see if it tries to start then.
