Try to unplug the mass airflow sensor and start it. It will idle higher but should run fine. If it works then you need a MAF sensor. Be sure you have an OBDII code puller to clear the computer when done

My '91 GMC Jimmy suddenly died like it was out of gas. It restarts, but idles rough, sputters and pulses. Plenty of fuel comes out of the injectors, but it wants to stall and die.

start at the beginning fuel pump pressure at the pressure regulator then look for ignition problems , check mass air flow sensor if equiped

because the combustion inside the engine is going wrong the quantity of air getting inside is not the needed quantity maybe less than or more in cold will cause such problem once the engine warm up than the engine temperature is up you will not find this problem because the point of firing will be near
