87 7mge not starting

[Jrsinnovations]

Hi to all, my 87 7mge is not starting. I have replaced the maf with a rebuilt one. I have also bought a used distributor and I another used ignitor with a new coil. Now ever since the car hasnt started I have switched the sparkplugs to ngk iridiums and I also got a set of semi used ngk cables from my buddy which are on the car. Since my throttle body positioning sensor was broken and cracked and the spring was seized, I replaced it with a used one that looking clean and the spring had good tension on it. Now I removed the top half of the timing cover to ensure that time was correct when I set the crankshaft pulley at zero and it was so I made sure that the distributor was set by the markings on the distributor body to the shaft hole. Now the car seems like it wants to start but it turns off If I give it gas while the car is trying to start it dies can anyone help me with this? I need my car to go to school which happens to be UTI lol it's my first year going. Need help please can anyone tell me what to check for?
