SOURCE: 1987 GMC sierra , no fuel pump power.

The inline fuel pump fuse on the passenger side firewall is good? Are you jumping it with 12 volts at the test lead or the fuse?

Happens all the time with 70's 80's and 90's GMC trucks. Replace the control module in the distributor cap.

It is probably the fuel pump. If I remember the number correctly, this fuel system needs about 50 lbs to open a valve.
Until this valve opens, no fuel gets to the fuel nozzels.

93 gmc sierra sputtering and tryin to die on me
It sounds more like the timing chain jumped a tooth or five. It is possible the fuel injection management module (or whatever GM calls them...) could have gone bad and is not providing sufficient voltage to the injectors.
One or two injectors wouldn't cause the problem you're describing. If they're all clogged, check for contaminants in the fuel system.

89 GMC 5.7L. P/U When driving after a few miles the truck dies. Let it cool down and it starts back up till it warms up then it dies again.Sometimes i go 2 miles or 20 miles just depends.
Check the primary and secondary resistance of your coil. Also check spark plug wire resistance. The coil will short out when it heats up if it is going bad.

It sounds like your alternator might be starting to go bad and the Battery Light is coming on because it is not charging the battery correctly. Have your Alternator checked with a volt meter, it should be reading 13 to 14 volts if working correctly. If not, replace your alternator.

From red light truck started sputtering and and stalled out
Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

Just a thought, have you checked yout TPS(throttle position sensor)? I had similar problems with my 89 GMC Jimmy 4.3l, however a code 44 is strange. Also check to see if your problems go away if you advance the timing a few degree's.

Hope this helps
