1997 chevrolet 1500. Fuel pump is working with good pressure, it have spark and the fuel injectors are working. The problem is engine will crank but it won't start; but if you introduce starting fluid throw the intake the engine will start and it won't turn off until you close the ignition switch (in other words you can drive all day the problem is to start). I change fuel pump, crankshaft position sensor, air flow meter, fuel pressure regulator and all intake gaskets. PLEASE HELP

Does your battery go dead?

SOURCE: i changed my intake gasket, and now wont start!

re-torque the intake manifold bolts in the proper pattern. also check that the hose from the filter to the throttle body is hooked up correctly with no air leaks

SOURCE: intake gasket went bad on 1998 chevrolet lumina

There is None to my knowledge.. Ive done thousands of them.. Its way too hard to explain.. I did my first one by the seat of my pants.. only advice I can give is : Dont mix up the pushrods!! If ya do,, it'll warp valves bc the intake and exaust push rods are different lengths

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

That normally means that you have a issue with your gas cap try replacing your gas cap first then diconnect the negative terminal of the battery for about three minutes to clear the memory and start the truck again
