Yes, it could be the fuel pump. But let me address some other possibilities first. (1) Those cars are super picky about their spark plugs and wires. What spark plugs did you use? Did you change the wires too? (2) Have you run a spark test on it at the coils yet? Coils can pretty randomly go out on these cars.
First off, checking for sparks is pretty simple. Just get a spark tester and hook it up to one of the plug wires (where it connects to the coil). Here is the in-line spark tester that I have: https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester
- it's also available at the local parts shops.
If you find one or two plugs that are bad, replace their individual coils. The images below contain instructions on replacing the coils.
Fuel pump information is below.
Fuel pressure can be tested by borrowing a gauge from the local parts store (AutoZone, Advance Auto, O'reillys). Herei s a general how-to guide that we've written up: https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator
I am also attaching AllData's information regarding fuel pressure and how to test it in the images below. Run this check and see what comes up. You should get 41-47psi with the key on and engine off.
And no, you cannot replace this pump without dropping the tank. For simplicity's sake, I will attach AllData's instructions for replacing the pump in the next post momentarily.
