How do you know you have a fuel system problem?

Start by checking my post "The Basics".

No 1.5 in a Lumina van.....sure you have the vehicle right?

Might not have a bad injector. Could simply be clogged.

What does your fuel pressure test reveal? What does your service manual say?

Have to start with the basics (below) or things get expensive VERY fast

Still need to know what the fuel pressure is to know what we are dealing with here.

A bad ground can shut off the injectors and cause you to think that you do not have injector pulse.

Hook a noid light up into the fuel injector harness (any parts store has them, they are cheap). Crank the van. Tell us if the light pulses or not. If it does not, your problem is electrical, not fuel related.

i checked out everything and found that both injectord are bad is it uncommon for both to go out at the same time?

Sure. A short could wipe them both out.

What did the noid light test I told you earlier reveal?

Did you try this method?
