I have been running into a problem with my 95' Blazer in that it is intermit starting. I turn the key and the engine cranks but doesn't fire. I can turn it off and on maybe 20 times and no start. Then all of a sudden it starts normal and runs without a problem. I turn it off and try to start it 20 minutes later and same ritual. It starts anywhere from the first time to maybe 20-30 times of trying. I tried replaceing the Fuel pump relay (everyone kept telling me that was it) but it did not cure it. Any other sugguestion would be very welcome....
