I have a 1984 S-10 Blazer since it was new almost 29 years agoExplain how a new fuel pump doesn't workI only had that once on my 1965 corvetteA new pump had been assembled with thediaphragm outside on a couple holes,a quick fixYou must have fuel to the carb & thus you needto take the carb apart & work on thatSo far I found that NAPA is the only source fora carb kit

Cheap pumps??

If it takes several tries to start on the first attempt, you may have a problem with the fuel pump relay or the check valve in the pump.The relay may not be powering the pump until the engine has oil pressure, and the check valve in the pump may be letting the fuel pressure drop back into the tank.I would have the fuel pressure checked after sitting overnight.

Sounds to me like if your voltage is high that your alt is going bad. Id check the batt with a meter while the car is running. If your alt is over charging then odds are then its going bad.

check with a timing light if the timing is correct.

Your diagram is below. Since the starter jumps at the solenoid, the problem would be the ignition switch, the clutch interlock, or the wiring. Check for power at the yellow wire that goes to the switch under the clutch pedal when the key is turned to start. If you have power on the red wires to the ignition switch but no power coming out when the key is turned to start, replace the switch. If you DO have power on the yellow wire, try bypassing the interlock by pulling the connector off and connecting the terminals inside the connector with a large paperclip. If that doesn't work, the purple wire from the interlock to the starter solenoid may be broken. Please let me know if you have more questions.
