91 Chevy Silverado idles but doesn't stay on

Asked by Apr 20, 2016 at 03:41 PM about the Chevrolet Silverado 1500

Question type: Maintenance & Repair

I've been working on my 1991 Chevy Silverado
1500 and I've replaced the fuel pump, fuel pump
relay, along with the filter. Yet it only idles when I put
gas into the throttle body and doesn't stay running.
What could be the problem? And how would I fix it?

I'd replace a few sensors...the IAT sensor on the plenum is responsible for measuring the outside air temperature and adjusts the mix~ http://www.summitracing.com/parts/dfp- ts10077? seid=srese1&gclid=Cj0KEQjw0dy4BRCuuL_e5MeqmNABEiQAq8 iNI_p_6GyIkbqkLZ1IfO8nH6SEIPZMq8yiYekfInxirqMaAksw8P8HA Q
