I'm working on a 1995 Chevy S-10 Blazer w/a 4.3 liter engine. It wouldn't start w/o manually priming it & then it would stall out after the fuel I primed it with ran out or when accelerated past 1.5 RPMs. Put a fuel pressure gauge on it & it has 60 psi and maintains it. New parts installed in hopes to fix prob; EGR valve, removed fuel tank & cleaned, added fresh gas, flushed & cleaned fuel lines, installed new tank vent valve, installed new fuel pump strainer, installed new fuel pump filter & a new inline fuel filter, installed new fuel pressure regulator, installed a new fuel pressure relay, installed new coil, and installed new crank sensor. Now it starts with key w/o priming & idles great for hours. Motor sounds strong, but if u try to drive it. It stalls out & dies at 1.5 RPMs. It has good strong spark, great fuel pressure, and we also checked the spider injection system, and it has no leaks. We are STUCK! Please help! This is a time sensitive matter! Respond asap.
Thanks for this site, I love it.
