hey guys, i have a 99 silverado v6. It died on me driving down the road the other day. Would crank over but no start. After about 45 minutes, i got a jump start and it fired up, battery died from trying to start it. Went to gas station, filled up, drove back home, all good. Couple days later went to drive it again, no start. Have spark, have fuel. Replaced the ignition control module, started right up. Drove up and down the street, all good. Went to drive gain the next day, wont start again. Turns over, just no go. Replaced the crank position sensor, still no go. Any thoughts? Doesnt have any check engine lights. HELP!!!

What is the fuel pressure? Just because you have fuel doesn't mean it's enough. Have you tried some staring fluid when it won't start?

I pushed on the shraeder valve in the back of the manifold and cranked the engine, lots of pressure, not with a gauge though. Yes i put fluid down the throttle body, still no go.
