Default Help me plz

New to the forums. Hope
fully someone can help. LolHave a 99 Silverado ext cab 5.3 newer body style cranks but won’t start. I’ve checked all the fuses, new battery, fuel pumps working, changed crankshaft sensor cause it threw the code three times. It will run off starter fluid. Any suggestions would be great. Thanx

Did you check the fuel pressure? Just because the fuel pump is working doesn't mean it is getting enough fuel pressure. It is running on starter fluid so this means it is not an electrical issue.

when my 93 had these same symptoms a new ICM in the distributor fixed it. Would run if gas was put in throttle body; fuel pump ran, injectors didn't fire
