Okay fuel injection guys I have a question. I have a 99 silverado with a 6.0L factory engine. It has problems starting. The engine sounds like it is starting so I let off the ignition and it dies. Some times it will start and run fine, then I shut it off and try it again and it won't start. The check engine light never comes on at any time. I have checked the fuel regulator on the fuel rail and cleaned around the throttle body with carb cleaner. Does anyone have any ideas?
fuel pressure test? spray some carb cleaner in t-body to see if it starts- if i had to guess- fuel pump- pressure drop will cause hard - no start especially cold- if it is put an A/C Delco pump in it- not aftermarket- my 2 cents- Chris
yep start with the filter (plugged) - it should be replaced more often- check the fuel pressure- there should be a shrader valve on the fuel lines- i can look tomorrow for specs at work or google it - maybe someone can chime in here- but i think it should be all of 50psi- good luck- Chris
fuel pressure on any LSx engine which includes the iron truck engines should be 58psi at all times. The engine should crank and run with 50 psi but there's a problem if you've only got 50 psi
