I have a 2000 silverado with a 4.3 L v-6. 144,000 mi.The other day I was going down the road and it just died. I shifted into neutral recranked it and drove on to work [20 miles] left work drove 1 mile it studdered and stalled and died. I cranked it but it did the same. I tried again and it just turned over will not start. The fuel pump is coming on the filter is not stopped up And its getting fuel up to the test port on the gas line. I cheked to see if its firing and it is. It will start by pouring gas into throtle body. It seems like the injectors are not working. please help

I checked the fuel pressure at the test port. The first reading was about 38 psi and each reading afterwards decreased untill i couldnt get a reading over 25 psi. I put a new filter on in case it was restricting the fuel. Did not fix my problem. So, then I checked my fuel pressure behind my filter close to the pump and still only 25 psi. Do you think it is my fuel pump not producing enough pressure? Thanks very much 4 your time.

I would say that is accurate. You need to make sure you have good power and gound going to the connector at the pump. If so, It's pump time. I would use an A/C delco on it. Don't forget the Strainer and a new filter at the same time.

Suggested Repair

Confirm good power and ground at the fuel pump connector. If both are present, replace the fuel pump with an AC Delco unit and install a new strainer and fuel filter at the same time.

Conversation Summary

A 2000 Chevrolet Silverado 4.3L died while driving and would not restart, although it had spark and would start when fuel was poured into the throttle body. Fuel pressure fell from about 38 psi to 25 psi and remained about 25 psi near the pump after a new filter was installed. The expert said to verify power and ground at the pump connector and, if those are good, replace the fuel pump, strainer, and filter.
