SOURCE: 90 chevy 350 with TBI starts but wont stay running

I have a 90 chevy k1500 350 tbi with same problem! I have traced problem to... after turning on key fuel pump kicks on when u crank it over injectors shoot gas and truck starts! After few seconds injectors stop spraying and truck dies! This can happen many times over and over! Eventually sometimes truck stays running and all is great! I changed ignition module, oil pressure sending unit (which i was told controls gas after vehicle is running) fuel filter, computer, fuel pump relay, I am at a loss now! Hope this helps and hope someone can help me!

My 350 tbi engine starts up, runs fine til it get warn, then it starts missing, chokes out etc.why?


probably Idle air control valve or EGR. under the dash there is a diagnostic port! with key off bridge terminal A & B turn key to on position (do not start) this will flash any trouble codes VIA the check engine light the first blink(s) are confirmation. then count blinks EXP,*** **= 32 , ***** ***= 53 , ** ********= 28... then just google GM OBD1 trouble codes and see what the problem is . 1_30_2013_3_58_06_am.jpg

89 K5 Blazer 350 TBI cranks but won't start... the rad hose blew, i fixed it then the next day it bogged and backfired, ran fine cold, but when warmed up it would lose power and stall when trying


Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

90 chevy 4/4 pu tbi 350 floods out


I'm having the same trouble with the flooding after warm start...if it's the temp sensor, would the temp gauge be working? It's in a 1991 Chevy van with an injected 350 carb.

Car starts cold but not hot


check your fuel pump pressure , it could be you have a fuel pump that is getting hot and breaking down..

My 1991 GMC with a 350 V8 is hard to start. Runs ok once started.


check fuel pump for proper pressure....Also very common is a bad o2 sensor not allowing enough fuel.

Hi I have a 1992 silverado with a 350,hard to start.


When it runs really rough is there alot of black smoke? Could be the fuel pressure regulator diaphram, real easy to change on that TBI...
