Have you changed the fuel filter and emptied the gas tank and put fresh gas in? Stale gas will not start as well as fresh gas and there could be water from condensation in the tank.

If the pump pressure and the fuel filter is ok, then you need to check the fuel regulator and make sure it is not weak and check the injectors to be sure they are injecting fuel just before the engine or as the engine rolls over. If you are spraying ether into the engine and it starts you have a lack of fuel on start up.

Try spraying a couple shots of carb spray down the throttle body while a helper cranks it over. If it starts and runs for a couple of seconds check fuel pressure and the resistance of the injectors.

Check fuel pressure it should be at least 52 psi if anything less replace fuel pump.If pressure is good then pull vacuum line off of the fuel pressure regulator and if fuel runs out replace regulator.

Vortec 350 knock on start-up.


Is it a ping or a knock? It could be the initial timing is not set correctly. Are you losing coolant? It could be a leaking head gasket and is leaking a small amount of anti-freeze into one of the cylinders. If it is a bearing it will get worse and worse, is the oil pressure good? I guess I'd take it back to the rebuilder.

Hard to start chevy 350 vortec


You will need to do a fuel pump pressure leak-down test, the pump must not loose more than 5 PSI overnight, u will need a cheap fuel pressure test guage, the test port is on the fuel supply rail to the injectors on the intake manifold, it looks like a tire valve but metal with a plastic cap on it, u may be able to borrow this guage from Kragen, Autozone or a parts store like them, if not they are very cheap, less than $20 US. Run the engine with the test guage hooked up, turn off the engine and then check it in an hour or so, if it drops more than 5 PSI then u will need to replace the fuel pump in the gas tank. One note make sure the connection for the guage is tight with no leakage or the test is invalid

1996 silverado 5.7 vortec cranks but wont start. fuel pump, gauges, "idiot" lights, blinkers do not work. flashers and all the rest of lights operate. Just replaced coil and this happens


Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.
