Also ecm has code 54 stored

Make sure the ecm/batt fuse in the fuse block behind the left side of instrument panel is not blown and has power to it all the time.

Also that the fuel pump relay does click once when the key is turn to run, before you turn the key to start.

Ask Your Own Chevy Question

54 is for the fuel pump circuit

Ask Your Own Chevy Question

If the fuel pump relay does not click, check if the dark green/white wire t it gets hot for them first 2 seconds.

Check fuse look good, replaced it with new one anyway

That doesn't mean it has voltage

Ask Your Own Chevy Question

Do you have a voltmeter or at least a 12 volt test light?

Customer reply replied 5 months ago
Have volt meter

Check both sides of that fuse for voltage and it should be 12 volts

Ask Your Own Chevy Question
Customer reply replied 5 months ago
Can I test for volts and get back with you later, without havin to pay again?
