Hello. My name is ***** ***** I will be helping you today.

Whats the security light doing? Cranking is not an indication one way or another for the security system.
If it disaabled the starter then that may be the case but since it dont thats meaningless.

When you crank it it blinks a red light
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

Then your thinking is wrong. It very much IS a security system issue.

Do you have another key you can try?

Loctronics i've never seen it before either this is actually my brother-in-law's van but I had one just like it and it had nothing like that
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

I just pulled up a diagram on that and its just a starter disable. Pure gimmick if you ask me but not part of your problem. If the starters working thats fine.

What is your fuel pressure?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
I just disconnected the line from the fuel pump to the fuel filter and got nothing
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

Did you not say in your original question it had good fuel pressure?

When you cycle the key can you hear the pump running?

If you bang on the tank while someone is cranking it does it start pumping fuel?

I checked up by the rail it must've been residual pressure I disconnected it from the fuel filter turn the key got nothing
Customer reply replied 1 year ago

Also just to be sure does it have gas in it? Does the tank sound hollow?

Many times Ive seen them where they have been driving 300 miles and the gas gauge shows half a tank so they think it still has gas and never noticed they ran out.

When I bang on the tank it still doesn't send any fuel and I can't hear the pump I even put a screwdriver up to the tank and put my ear to the screwdriver and still can't hear the pump
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

Try jumpering across pins 30 and 87 at the relay and see if that gets it running.

Ask Your Own Chevy Question
Customer reply replied 1 year ago
It does sound a little hollow but my brother-in-law put a gallon of gas in it so there is gas in the tank I do have gas on hand if you think I should put more in
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

Is it parked flat? Theres a lot of surface on the bottom of the tank... one gallon wont raise the level that much. If its parked with the front end slightly downhill that would never touch the fuel pump.

Whats the gas gauge show?

I dont think it would be a bad idea to try a few gallons of gas either way.

Ask Your Own Chevy Question
Customer reply replied 1 year ago
I jumped 87 and 30 and nothing
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

OK, It sounds like a bad fuel pump then. Do you have a multimeter or test light? If so check voltage on 30

1/4 tank
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

And you have power?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
I just dumped five more gallons of fuel in the tank still got nothing I tested for power at the relay and I do have power
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

Well your next step is to drop the tank and verify the power is making it to the sending unit. If so it needs a new pump/sending unit assembly.

Which wires would it be I have a red a green or white or gray with a black stripe a black a purple with white stripe solid gray solid purple
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

The grey and black are the fuel pump.

Customer reply replied 1 year ago
I have power to the pump
Chevy Mechanic: Kavey, Shop Owner replied 1 year ago

If you have power and ground to the pump and its not pumping you need a new sending unit/fuel pump assembly.

If you got a little time to wait HERE is a Delco for 125 shipped.
