BTW why did you need to find it?
i thought that it was the problem but the car wont start. i have spark, and i put a paper clip in the diag. base and i ran the fuel pump and it turned on. i thought it was the pressure regulator but i was wrong...:) i know the fuel pump works but i could be old and working slow right? Please let me know what you guys think im lost...

I most cases, if the engine runs when the +B & FP terminals are jumpered in the DLC (diagnostic link connector, which is what I think you did), the problem is most likely with the circuit opening relay. This relay is mounted on a bracket on your ECU. If you can get your hands on a spare, plug a differnt one in and see if it works. If it does, you solved your problem. If not, you likely have a wiring problem in the circuit to or from the circuit opening relay.

I would remove the large hose that attaches to your throttle body, open up the throttle plate, and spray some fuel into the intake manifold. Put the large hose back on the throttle body, then try starting it. Does it start or try to start this way?

If it does start and run for a second or two, then something is not letting your fuel injectors operate.

If it doesn't try to start at all, then I would check your cylinder compression pressure on each cylinder, and/or check your timing on your timing belt (crankshaft to camshaft). Because you have spark, we know the camshafts are rotating, but we don't know if the timing belt jumped a few teeth and lost its timing.

How many miles has it been since the timing belt was last changed?

Good job in finding the problem and getting it fixed.

When someone tells me they have spark (like you did), my interpretation of that is all spark plugs were checked on all spark plug wires, and there was spark on all of them. This isn't what you meant. That throws us off in trying to help a bit. But I'm glad you fixed it.

I have a 1991 toyota GT and I noticed my fuel pressure regulator has no hose on it connected and I've been trying to find where the other end is where the hose is because as of now my car will start and run bit won't rev over 2-3 grand then it'll die randomly but start back up after a few times trying to start it and sometimes it'll run normal but most not I've done a lot of work to the car like ignitor ignition coil timing little over 1000 miles ago fuel pump and fuel filter was most recent done more stuff but just looking for where the fuel pressure regulator hose goes to pics diagram anything that could show me and help me run a new or maybe find the old ive looked all over the back side of the engine to see where it could be but can't see anything
