Hi, your engine does not have a MAF sensor. the computer uses a combination of MAP and throttle position sensor inputs to calculate the injector pulse width. Is there a problem we can help you solve?

SOURCE: where do i find a knock sensor a 1993 gmc sierra

Should be on the right side of the engine by the starter.Has a 1 wire connector.It does not go into the cooling system so you can just take it out without draining the coolant.Hope this helps.Good luck.

1998 GMC Sierra 2500 5.7L hard cold starts last month, now won't start cold w/o a little carb cleaner in intake. Codes for oxy sensors, mass air sensor and crank/cam position. Drove today, no power just...

starting definately has a lot to do with the crank/cam position sensors, but it wouldnt have nothing to do with hot or cold weather, oxygen sensor will make the vehicle run too rich if its out, you will smell fuel very strong out the exhaust, that could make it run sluggish also, and usually if the mass air flow sensor goes out the vehicle wont start at all...

Won't Idle

if it starts for a few moments chances are that all systems are ok for the basics, fuel, spark, compression. What is most likley the cause is either a security system problem, or a problem with a mass air flow or other sensor, your thinking is semi accurate but remember to KISS keep it simple sunny.

P0102 is mass air flow sensor circuit, low input the MAF is attached to the air cleaner where the hose runs out of it... Unplug it and check the voltage supply and the ground... looking into the plug, with the tab facing up, there will be 3 connecters inside it, left to right they are.... sensor signal, ground and supply.... make sure you have 12 volts at your supply and the ground is good good luck
