I have been checking on the automotive forums for Suburban no start problems and have tried some of the solutions, but my vehicle still doesn't start. Here is where I'm at: I have spark, fuel pressure at the throttle body, the fuel pump in the tank is working, new cap, rotor, coil, module, fuel filter, and ECM.
I just ran the truck 2 days ago for 10 minutes to flush the radiator, turned it off to install a new t/stat, then it wouldn't start again. I have tried starting fluid, gasoline, it cranks but no fire, not even a sputter. The pump has been replaced probably 9 years ago. The only other thing not replaced is the pickup coil in the distributer, although the distributer was rebuilt about 10 to 12 years ago. This vehicle just sits until needed, can't afford to drive it daily. The truck is a 1987 Suburban 1/2 ton 350K engine, automatic, 4wd. I'm stumped and really need to know where to go/check/replace next. Any help would be appreciated. Thanks.

If you have good blue spark at the plugs it should kick over with starting fluid.

you post says spark and with fuel dumped into the TBI you get nothing.
timing chain ? timing off ? check the vehicle engine grounds also.
remove #1 plug rotate to TDC check distributor.
