injector problems with 5.3L in 76 nova okay im almost done with my swap! try to do a start up today and the engine is turning over but will never start. i checked the usuals getting spark to the spark plugs, getting fuel to the rail but i cannot get nothing out of the injectors tried chasing some wires with nothing coming back as bad. please help me lol
I'm freshining up a truck intake for a carb to EFI swap. Nice trick with the Seafoam. I'll give them a soak while its all apart. THANKS!
Have you checked to make sure you are getting a pules signal from the ECM ?, pick up a Noid light to check by connecting it to the harness end and crank it over to see if it lights up or not.
You might check the resistance across the injectors two terminals, should be around 14 ohms.
You can try the lift the injector/rail off the manifold and raise it up some, place a paper towel under it and then crank the engine over to see if it is spraying or not.
Just a few things to check. good luck

will it run on starting fluid ?
have you checked to make sure you have constant pluse to injectors ?
VATS will let the injectors pulse 3 times and then shuts them down , if while cranking it pluses a couple times and then stops , you have a VATS issue
