Question about 2005 Chevrolet Express

1 Answer

I have a 2000 chevy express 2500, just had the fuel pump replaced a few weeks ago and it died again on me but started right back after a couple of days as if nothing happened. I even took a chance to drive it for over 300 miles and it still was running great, no stalling, no warning lights, i ran a diagnosis on the computer with a scanner and got no trouble codes...and suddenly, it happened again, it died! And now i don't hear the fuel pump noise when i turn the ignition key on, i replaced the fuel pump relay, still nothing... i'm running out of options so please, somebody give me some good news! Thanks.

SOURCE: HARD STARTING PROBLEM

Fuel Filters need to be changed EVERY 15,000 Mi and oil changes once a year maybe,maybe every two years
Common Problem for the cargo is that the distributor gets moisture in it due to the vent being plugged up, And the Cap and rotor have been Known to cause your symptoms use only GENUINE dELCO PARTS IN YOUR VAN TO ASSURE THE PROPER PERFORMANCE

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Hey I had my rotor and all that stuff replaced on my 2000 astro van, Intermittently it would not run, The problem was I hit a puddle one day and water flew up on top of the roter like 3 drops, it created a trace( it was arching) Thats why it was intermittent.Take a look at the cap look for like a discoloration on it clean it and put it back on.Sounds too easy but remember I had all new parts too.

SOURCE: On my 2003 Express, the warning lights come on

1-This is an intermittent problem then a diagnosis probably could not show an error code. 2- Sometimes it almost stalls the engine then you don't have a right Air:Gas ratio 14.6:1. This ratio is to maintain a good combustion in the engine. This is control by ECM through output from the Oxygen sensor. When this sensor is bad it doesn't give correct information to ECM to control delivered gas. 3- A weak Fuel pump and a bad Fuel Accumulator not maintaining correct gas pressure for Fuel distributor could cause this problem.

Fuel Cut Solenoid: Testing and Inspection
An inoperative shutdown solenoid can cause a no-start condition. Disconnect solenoid harness connector and with ignition switch in the "ON"
position momentarily touch solenoid harness connector to solenoid connector. If a "click" sound is heard, the solenoid circuit is operating
properly. If "click" is not heard, the system should be diagnosed as follows:
1. With test lamp connected to ground and the ignition switch in the "ON" position, backprobe the shutdown harness connector. If the test lamp
does not light check for open circuit form the ignition switch to the solenoid.
2. If the test lamp lights, check the ground circuit between solenoid stud and injection pump cover to see if connectors are clean and tight. If the
connections are not clean and tight repair and retest.
3. If the ground circuit is "OK", remove the injection pump cover. Connect a jumper wire between solenoid ground connector and ground. With
the ignition switch in the "ON" position, momentarily touch shutdown solenoid harness connector to shutdown solenoid terminal. If solenoid
operates, check for internal injection pump problem.
4. If the solenoid will not operate, replace the shutdown solenoid.

2000 chevy express 5.0 2500 series starts,runs and dies all in 10 seconds. changed fuel pump, filter, pressure regulator, and starter(only cause sparks were comming from the solenoid)


Try swapping out the fuel pump relay, if thats good try testing your ignition system components. Start with the module and coil pack. If they are ok check the crank position or cam position sensor (which ever applies).

I think your problem might be your fuel relay which is situated next to the fuse box in the engine compartment.
