Help with 89 K5 Blazer after collision Sign In

1989 K5 Blazer (chevy) 350 engine 127k miles

Got into a wreck in this vehicle and now it wont start. Minimal body damage but it wont turn over. The fuel pump comes on, there is spark from coil and the number 1 plug, fuel injecters have pulse, poured fuel into throttle body and will start but dies out when fuel is gone... Thats pretty much it, can someone advise me on any possibilities as to what this might be? Thanks for reading, and I hope someone can advise !!! Mad

If you're positive about the injector pulse, then you need to use a fuel pressure gauge and monitor what the pressure does. This is a low pressure TBI system but still has to maintain over 9 PSI at all times.
