I've tried to find an answer in previous threads with no success.
I have a 1990 Silverado 1/2ton 2WD, 5.7 liter 700R4. 320,000Kms
Vehicle had been running great, drove home from work, parked it, next morning wouldn't start. Cranked over no problem, just doesn't fire up.
Month before problem I installed new cap & rotor, and spark plugs.
What I've checked:
-I have fuel
-Injectors are working
-fuel pump works
-have spark
-checked new cap and rotor - appears fine
-pulled a spark plug to check for flooding - none
-added fuel in throttlebody- no change
-tried a new coil - no change
I figure with both fuel and spark it should fire up, - no!
Haven't been able to check without assistant.
-ignition timing
Is it possible the timing chain has jumped?
something inside dist. has shifted/failed?
Once again have fuel and spark, cranks over well, just doesn't fire up.
