Those are lean codes and a MAF (P0101) code. Make sure the MAF sensor is plugged in, and there are no leaks/ loose hoses between the air filter and the engine. You may have a vac leak at the intake also, but check these first, If all appears OK a repair shop will need to check it out for you.

I have a 2000 gmc Sierra 3/4 ton 4x4 k series I have no spark to my spark plugs I have changed the crank sensor an the ignition module not sure what else I can try I'm thinking maybe the ignition coil


Check to see if you are getting spark from the coil to the distributor. I suppose the engine is a 5.7 liter?If not getting spark to the cap, then check for power and ground pulse at the coil.If there is spark at the cap, replace the ignition rotor. If there is no power or ground pulse at the coil,check to see if the ignition rotor is spinning when the starter is engaged. If the distributor is not spinning while cranking the engine there are several more things you'll need to check,i.e.,distributor gear and pin as well as oil pump if the pin or gear are damaged.

We changed spark plugs & wires on our 1991 GMC & seem to have the order wrong on the distributor cap because truck won't start. need diagram


Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.
