Asking the God's
Does anyone having ideas why on startup my truck is stumbling and sometimes won't start. After it comes up to speed it is fine. I have been running 92 octane because it all most impossible to find 93. :grr: around here. Allen said it would be fine but I am not sure. I am not getting any codes so I'm not sure what to look for.
Any ideas will be considered
Thanks
:help:
Check fuel pressure at startup. While you have the gauge on the fuel line check for fuel pressure fluctuation, it should stay consistant.. Check for vacuum leaks or cracked hoses.
Thanks RHB I will check that out. And for the leaks but shouln't I get a code for that?
Thanks again :thumb:
Nope, GM hasn't gotten smart enough to put an inline fuel pressure sensor on thier vehicles yet.
