Weird Fuel Pump Issue
Every once in a while now my C32 will just crank and crank and never turn over. When it first happened I changed the CPS and no luck.
So next I checked for fuel and spark. Found the issue was no pressure on the fuel rail. After I took the cover off the pump in the rear drivers side seat the car magically started just fine and was perfect for months.
Now occasionally it does the same thing and won't start. When it happens I can lift up the cover over the pump and it basically sounds like it's pressurized. So I'm assuming back pressure or something is stopping the pump.
Anyone ever seen this or have any suggestions?
