I have a 1990 240sx and my car just started dumping gas in the crank. The compression is good across all for valves and all injectors and fuel pressure regulator. PLease help.

I have the exact same car with the exact same problem. For me it was my fuel injectors. I swapped them out with some used ones from a junkyard and that solved the problem. We looked at the injectors under a magnifying glass and found microcracks that had allowed gas to drip through once the car was shut off. The gas then slips by the piston rings and into the crank. There are other reasons for the gas and this one is the most expensive. OEM injectors are $175each and rebuilts are $95each. Good luck

dude, if you've got new ones then I wouldn't check'em. Mine had over 150K miles on'em.
