Re: 1990 GMC SIERRA starting issue 350 tbi v-8
Sounds like possibly it may be taking longer than normal to get fuel possibly.......... I had an 88 full size Jimmy with the TBI, chack that your injectors are not leaking on top. To see this simply remove the air cleaner cover, start the truck and have a look around the top of the injectors , you should not see any fuel. Another thing to try is pouring a bottle of injector cleaner into the tank.
