Got a good head scratcher here, friend has his tahoe towed to me to see if I can fix. It will crank over, but will not start. I have checked the fuel, we have 60 lbs pressure, we have spark, as can pour some gas in to the throttle body, and it will run. so that would mean the crankshaft sensor is good, and the emc is good. I have changed out the spider, thinking that was the problem, but still the same. anyone knows what could be wrong??
