Hope all is well, finally I have a picture of the number stamped on the injection pump. The following is stamped on the pump: Pump NO: 104646-6021 NP-VE4/11F2000LNP1682
This the pump on my isuzu pick up. I am not sure if the pump has a malfunction, the following symptoms i have detected: when starting the engine in the morning the engine starts well but after couple minutes on idle the engine makes a sound like it wants to shut down, then i need to prime the fuel system. this happens only when the engine stands the whole night. Do you an troubleshooting guide or manual of this pump? My mechanic says the injection pump should rebuild, but I have some doubts about that.
Please need your advise.
Looking forward to hear from you. Thank you in advance.
