Hubby needs a schematic on a Bosch fuel injector pump, antique truck, part numbers 9275224 PES4A80D 410-3R5 2523 0400864044. thx norma [email protected]

it goes by the engine code. cutting out, can be a number of things if there is no code, i.e fuel pump. blocked filter. a relay fuel/injector. can also be the ring for the ignition key sensor (Code sometimes). can also be the fuel pressure sensor, oil sensor. or a filed plug socket seal. all these can stop engine with no codes or random codes.

Do you mean Stearman? Made by Boeing Aircraft the Stearman was made for the US Army, Navy and Air force and has a number of variants. Almost all by a few are now in private hands and the most common variant is the Stearman Model 75. You didn't specify the schematic you require, either. Electric, Fuel, Hydraulic or whatever. When asking questions you need to be as accurate and a specific as possible. Also be careful of automatic spell checkers that will change Stearman for Steadman without you even knowing!!

Schematic?
WELL, if it is a gasoline engine (you did not specify), there isn't much to the "fuel system..." only a single line with one or two pumps routing fuel to the fuel pressure regulator, and a single fuel line from the fuel pressure regulator routing bypass fuel back to the tank. Oh... and the fuel rail and injectors, which are all connected to the fuel pressure regulator.
If it is a diesel engine, it is even simpler!
Why would you need a diagram??

PGM-FI Main Relay

Print
This relay is located behind the dashboard's lower cover. It consists of two individual relays. One is energized whenever the ignition is ON , thus supplying battery voltage to the Powertrain Control Module (PCM). This relay also supplies voltage to the fuel injectors, and power to the second relay. The second relay is energized for two seconds, when the engine is turned ON , to power the fuel pump.
See Figure 1

Fig. Fig. 1: Schematic of the PGM-FI relay
Testing
If the engine starts and continues to run, the PGM-FI relay is working and does not need to be replaced.
See Figure 2

Fig. Fig. 2: PGM-FI relay terminal numbers

1. Remove the relay.
2. Apply battery voltage to the number three terminal.
3. Ground the number two terminal.
4. Check for continuity between terminals five and two.
5. If continuity is detected, proceed to the step 7.
6. If there is no continuity, replace the relay.
7. Connect the number four terminal to the positive side of the battery.
8. Ground the number two terminal of the relay.
9. Check for continuity between the number five terminal and the number two terminal of the relay.
10. If there is continuity, the relay checks out "OK". If the fuel pump still does not work, test the harness.
11. If there is no continuity, replace the relay and retest.

BBB Industries should list schematics back to 1986.

FIRST YOU NEED TO RELIEVE FUEL SYSTEM PRESSURE BY REMOVING FUEL FILLER CAP THEN DISCONNECT FUEL PUMP HARNESS OR UNPLUG FUEL PUMP CIRCUIT RELAY, THEN START ENGINE LET IT IDLE UNTIL DIE LACK OF FUEL.TO REMOVE FUEL INJECTOR YOU NEED TO REMOVE FUEL DELIVERY PIPE WITH FUEL INJECTORS AS A ASSEMBLY TO REMOVE FUEL INJECTOR.YOU NEED TO TAG NUMBER ALL VACUUM HOSES AND PCV VALVE,NUMBER TAG FUEL INJECTORS WIRE CONNECTORS SO YOU CAN PUT EVERY THING BACK IN RIGHT PLACE.

Hi!

Might be the Crank Position Sensor. or Cam position sensor. usually when there fail, The car stalls and wont start. Good luck

Get a professionally rebuilt pump. Don't try to mess with rebuilding yours, it isn't worth it. I know the rebuilt pumps are high ($450) plus, but it will pay off in reliability and performance.

If i knew what year make model car it was i could help better. But usually they are under the hood in a fuse relay box.take the cover off and flip it over. Some have a diagram of what fuse/relay controls what.

The two most common problem with these Honda's are the distributor and the "main relay"(this control the injector and fuel pump. Most of the time with a distributor problem you would get the problem that you have described. So in my opinion its a distributor, can be replace very easily.
