Pressing accelerator to hard car would shut off, over time wont start at all

I have a 89 ford probe 2.2L that has been sitting for a long time, just started restoring first couple of days the car would drive but would stall on right turns, after inspecting I notice a large powerful jet of power steering fluid squirting out of its hose all over the fuel inj. System. Replaced hose then left car alone for a few days. Yesterday the car would idle rough then cut off if I pressed the gas too fast but would slowly gain rpm. Now the car wont start it all. Ive been told the fuel injectors have clogged up because of the PS fluid squirting over them. Also could be a timing problem, on top of that in the process of trying to fix the stalling issue my little brother broke the (MAF) trying to make repairs himself. What should I check first?. ***Changed spark plugs(their getting good spark) fuel filter and about 5 gal. Of gas. Recently used that head gasket repair sand just as a procaution since its been years since its been used.
