Question I have a 93 s-10 blazer with a 4.3L I with CMPI fuel injection I have proper fuel pressure at the fuel rail and spark, but engine will not start it will fire but not startm any suggestions?
Answer Hi Russell... if you have fuel and spark it should run.... try this, remove all your plugs , clean and dri them.reinstall plugs... disconnect the fuel pump relay. take some air intake cleaner and spray into the breather and crank over. truck should start. reconnect the fuel pump relay, again spray air intake cleaner in the breather and crank. it should start and stay running now... if it doesn't you need to check why you are not getting fuel thru the inj...caution.... use only air intake cleaner not quick start.... hope this helps
