i have a 1994 s10 blazer and it will not start. I hooked up a fuel pressure gauge and i am gettring around 60lbs of pressure. I have no spark now. replaced coil, still nothing. replaced the ignition module and it started but then a few hours later no start again. Replaced rotor cap and rotor, then it started again. it ran fine for a few minutes and then it started to stall. it would start back up a few times but then it would stall. now it will not start period. getting no spark to the plugs. any ideas?

 

What was your fuel pressure leak down rate? A leak inside the intake could cause the stalling, but wouldn't cause a no-spark condition.
