Testing is the way to a fix . Fuel pump pressure testing , electrical testing . Viewing engine sensor data on a scan tool . Instead of guessing as to the problem learn to test or take it to a qualified repair shop . Changing ECU without doing it correctly can cause problems that were not there before . PCM - engine computers need to be programmed , dealer only.

SOURCE: venture van started running rough and barely starts

It sounds like you caught the fuel pump just in time. I would take it to you local mechanic to check it out.

When i try to start my 98 chevy venture minivan it turns over for about 20 sec then dies unless i pump the gas when i turn it over. what are all the possibilities of what could be causing this to happ


Turning over is engine cranking, not running. I'm not sure I understood your post?
Use a gage and check proper fuel pressure, 3.4L engine, 41--47 psi.
Any applicable trouble codes? To check codes yourself, at the least you need an obd2 code reader.
I'd want to check if system is running rich or lean?

2000 chevy venture doesnt start


check to make sure the security light is not on if it is the van will have spark but no injecter pulse the best way to solve this issue is to have the original igniton key and put it in the igniton in the run position and leave it on for 10 minutes then the light will flash then try to start the van

1993 Chevy Astro Mini Van not starting


if your mini van has a 4.3 litre engine v6, when you turn the key on you should be able to hear the electric fuel pump start. the fuel pump is inside the gas tank,if you hear the pump you might want to change the fuel filter. The thing about computerized engines and a throttlebody is that you need a fully charged battery to start work with.
