Will turn over but not start put a new fuel pump
I had the same problem with my old 1987 Chevy blazer s10. The problem was the ground wire of the fuel tank was rusty and it broke. So simple was the problem. But before that, I checked and change the fuses, the fuel filter, the oil pressure switch (this is related to the fuel pump to) and finely when a was ganging the fuel pump saw that the ground wire was broken or damage.
I hope this can help you.
Started motor fine a few minutes later it died
When you state "carb" I assume you mean TB as it should be Throttle Body Injection, unless it was converted.
You should be able to hear the fuel pump in the tank prime for about 2 seconds when you first turn the key on. May have to get your helper to remove the gas cap and listen through the filler.
If you don't hear a buzzing sound then check the relays on the firewall. You can turn the key off, wait a couple seconds and then turn the key on and have your helper listen and feel for the relay that clicks.
Or look for the wires,
The relay will have a dark green/white from the ECM
Grey is power to the pump when the relay is enegized.
Orange is hot at all times. It comes from the ECM B fuse. Should check that as well if not done so.
Black/white is a ground.
Now most likely if your relay clicks when the key is turned on then its all fine and the fuel pump has gone out. The oil pressure switch also enegizes the pump when there is oil pressure.
Need Instructions on replacing fuel regulator on
Fuel Pressure Regulator - REMOVAL & INSTALLATION(see Figures 1, 2, 3, 4, 5 and 6)
- Relieve fuel system pressure. Disconnect the negative battery cable.
- Clean dirt and grease from the regulator retaining ring.
- If
equipped with a bolt on-type pressure regulator, remove the fuel return
line from the return tube by squeezing the tab and pulling it off.
- Disconnect the vacuum line from the regulator.
- If equipped with a bolt on-type regulator, perform the following:
- Remove the regulator attaching bolt(s)/screw(s) from the bracket.

- If equipped with a snapring-type regulator, perform the following:
- Remove the snapring from the regulator.
- Wrap
a towel around the regulator to catch any fuel that may escape. Remove
the regulator from the fuel rail using a twisting and pulling motion.

- Cover
all openings with masking tape to prevent dirt entry. If the regulator
is being reused, inspect the filter screen, if equipped, for
contamination. If contamination exists, replace the filter screen

snapring (7)To install:- If the regulator was disassembled, perform the following:
Lubricate all O-rings with clean engine oil prior to assembly.- Install a new regulator O-ring back-up and large O-ring.
- Install the regulator filter screen.
- Install the small regulator O-ring.
- If
the regulator is not being replaced with a new one, lubricate new
O-rings with clean engine oil, then position them on the old regulator.
Image
LINKFig. 6: If the regulator is not being replaced, remove and discard the old O-rings- If
necessary, connect the fuel return tube to the pressure regulator and
secure with the retaining nut. Tighten the nut to 13 ft. lbs. (17 Nm).
- Install the regulator into the regulator housing and seat with even pressure.
- Install the snapring or retaining bolt(s)/screw(s), as applicable.
- Attach the vacuum line to the regulator.
- If removed, connect the fuel return tube to the pressure regulator.
- Connect the negative battery cable.
- Turn the ignition switch ON and OFF to allow fuel pressure back into system. Check for leaks.
Hope helps.
How do you remove the
Typically there is a small allen screw on the bottom that holds it to the base that's glued to the glass. Loosen that screw and it will slide up and off.

I Have a 95 Chevy
You say light spark, Brown or blue in color. And what brand of plugs did you get?
I can pour gas into
I would say more than likely your problem is a clogged fuel filter or a bad fuel pump. To narrow this down, listen for the fuel pump 'priming' (making a whining noise from the gas tank) turn the key to the On position and you should hear this whining for about 3 seconds, if you can hear this the fuel pump works fine, if not it is probably time for a new one. As for the fuel filter being that it is a 1987, I would replace it even if it is not clogged, the easiest way to test if it is clogged though is to blow at through it with your mouth and if you feel any resistance then it needs replacing.
