My car wont start, It ran when i bought it but won't start Options

[turnaround89]

Little background first. Bought the car about a month ago and drove it around the neighborhood for a little while since it wasnt insured, never out on actual roads with other drivers. I got the insurance on the car and took it out for its first real drive. Drove the car for about 30 min and stopped at the bank to make a deposit. When i went back out the car would not start, couldn't even jump start the car. So i had to have it towed home, the drive cost me 50 dollars.

Well, i get the car back to the garage and start tearing into it, thinking it might be the starter, well i can't change the starter until the engine comes out(unless someone can help me there) but the starter seems fine, because i replaced the battery and the starter had lots more power. So new battery didn't make the car fire up, only the starter would crank the car, but no actual running engine. Replaced the spark plugs(they were horrible, gaped correctly) didn't do a thing. The starter cranks the engine but it will not fire up. I changed the fuel filter(and some of the fuel lines because they were horrible) today and that didn't help either. The old filter was pretty nasty. Hooked the fuel pump back up and the car still won't fire, starter cranks, but the engine won't turn over and start. I have ordered a new coil and spark plug wires. I had a friend with me and he watched the spark come through the wires and said it was really weak. However, if this doesn't solve my starting problem, what else could there be?

My dad says to check the timing and possibly the fuel pump might not even be working. The car ran two weeks ago, is it possible the fuel pump went out?

Oh yea, the car originally came with the 2.0L but the PO sold it and put a 1.8L carbed engine in. I can get more info about the engine if it helps.

Thanks everybody. Here are some pictures of the car, i am hoping for a 916 clone. I need the rear bumper and thats it(unless i want a steel roof, which i don't)

When you say the pump should turn on with the key in the first position are you talking about the accessory position on the ignition switch? Or is there a position before the accesory position? I wouldn't be asking that question if i were right next to the car, but the cars sits at a friends house who has a garage i can work on it in, so when i work on it, i have to drive there.

The engine is only a single carb setup.

How in the world can you pull the starter in 5 minutes, i can't get to the top bolt?And yes, the car is on jack stands.

thanks everybody, i will try to get some work done today, but i have a night class to go to, if not today, i will do it after class tomorrow!!
