1999 Chevy Blazer 4.3L engine has an electronic EGR valve its in front of and below the intake manifold a cylinder looking part connected to a small wiring harness. It is bolted on with 2 10mm bolts alot of times a piece of carbon will get stuck in the pintle at the bottom of the EGR valve and will keep it open causing a large vacuum leak making it hard or impossible to start. Good luck.

My buddy has a 1995 dodge 1500 with a 318 engine it has very low power has a skip in it. And lately has started popping through the intake. Im thinking timing chain Am i wrong?


You are probably correct. Check timing marks and make sure all lines up correctly. Make sure spark plug wires are installed correctly(not crossed) . Also, check for proper fuel pressure.

I have a Chevy sr10 Blazer 2000 , cranks but won't start , I do hear the fuel pump when I turn the ignition .


Have a helper crank it, while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check for a fuel injector pulse.
Can you check applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.

Is there a security lite on the dash? Is it flashing or anything?

96 chevy blazer turns over but wont start


It needs at least 60psi fuel pressue to start. You need to check fuel pressure with a gauge.
If the dist cap or rotor is bad, the spark will not be on the right plug at the right time. Same goes for a faulty distributor or a problem with the timing chain. And the ignition module.
Also check the ecm for trouble codes.

Looks like you've covered the basics, make sure the firing order is correct with your spark plug wire replacement. Hope this diagram helps.

THE FUEL PUMP IS BAD.

if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec
