wont start

[clark0031]

1989 suburban 350 fuel injected. Its never not started and this morning was the morning to pick to not start. Turns over with not even the slightest noise of not wanting to start.
The only thing i did different was put 2 gallons of old gas it it yesterday . I drove it for 30 mile errand last night. Ran fine. It only has a 1/8 of a tank left of fuel now. I havent investigated more yet. Any ideas?

Check for spark, then be sure fuel is coming out of the injectors.

Then we'll go from there

Yup, fuel air spark.

Hopefully the old gas wasn't dirty?

 

[readymix]

Fuel air and spark is all you need. Do you have some new gad to try?

 

[clark0031]

have spark. going to go get good fuel. Is there a fuel filter involved some where

 

[readymix]

IIRC is on the passenger side frame rail.

 

[clark0031]

fuel was clean . draining the fuel from my 66 mustang but the gas is a couple of years old

 

[clark0031]

just pull it off and replace it?

 

[readymix]

Yes. Just need a few wrenches and a little patience

 

[clark0031]

fuel goes right thru the fuel filter but not to the fuel injectors

 

[clark0031]

fuel passing thru the filter but not to the injectors

 

[clark0031]

got fuel racing through the filter but not to the injectors

 

[readymix]

Are the injectors firing?

 

[clark0031]

There's nothing spraying into the throttle bady

 

[readymix]

Can you hear the injectors firing? It makes a clicking noise.

 

[clark0031]

No .I have the air filter off and don't see anything either

That's your problem. Check the wiring first.
Need me to post up the troubleshooting steps for this?
