Question about 1991 Volvo 240

1 Answer

Vapor lock? My 91 240 generally runs great. But...I've recently moved to Vegas where it is very hot. The car motor shuts down after about 20 min of driving and will not restart for about 5-15 minutes. When it does restart, it runs fine for another few minutes until cutting out again. The it's fine at night or when the outside temperature drops under 100. How do I tell if this is an electrical or fuel delivery problem? Or is there another solution I'm missing?

98 and 99 intrepid was manufactured with weak fuel pumps causing them to vapor lock try pouring cool water on the fuel rails on the intake to calm vapored gas then try to start it. Even the temp gauge at half way mark is probably still low on coolant causing engine to be warmer than normal causing the vapor lock to fix this problem replace the fuel pump with a 2000 or newer intrepid fuel pump that carries a little higher psi to prevent vapor lock from reoccurring this pump is compatible with your 98 it will plug right in

2000 Mercedes CLK..I think it is a vapor lock problem..car starts as usual but 5-7 minutes later it just shuts down..happened in traffic..so I dont dare to drive it..Afterwards it doesnt start unril...


Sounds like the crankshaft position sensor needs to be replaced. They are a common problem with the Mercedes. That sensor is the one that the engine control module looks at to see if the engine is running. When they get hot and stop producing a signal the engine control module thinks the engine is not running and shuts of the fuel. After waiting awhile they cool down and the vehicle will start up again. I've changed many of them when I worked at the dealer. Tricky part is when there working and the car is running there will be no check engine light on or code stored. Usually will only have the code when the car won't start. Let me know what you end up finding out on it but that would be the first place to look and probably the cheapest.

CAR WONT STAY RUNNIG


is it fuel injected? you might have a faulty sensor it sounds like a vapor lock, also you fuel injectors might be dirty or bad also check fuel pump pressure or a cloged fuel filter, or it is putting to much gas if your vette has a carb.
