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

Why does it die when first drivin at stop lights/signs ?


power steering puts a lot of load on the engine and if the idle compensator does not adjust it dies. a struggling pump can cause more load. when pump gets warm it works easier. Notice how when you check fluid it says hot cold.
Hope this helps Mike

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

Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.
