radoss05 Posted July 7, 2009 Report Share Posted July 7, 2009 So the SSSwouldn't start again,it would crank but not start.So after about 7mins it started.I'm like what the F*** IS wrong,about a month ago it did the same thing to me, the dealer said they couldn't find anything wrong. I did change out my tune pcm for the stock one before i went to the dealer,maybe I should take the ss in with the tune pcm since the problem happens with that pcm on. Any info would be great guys I really would like to fix this problem before I get standed. tks Quote Link to comment Share on other sites More sharing options...

radoss05 Posted July 7, 2009 Author Report Share Posted July 7, 2009 No codes at all,Im assumig also that it is the fuel pump, but the dealer won't change it out under warranty untill it goes completely bad.tks Quote Link to comment Share on other sites More sharing options...

benjaminh2 Posted July 7, 2009 Report Share Posted July 7, 2009 (edited) fuel pumps rarely "act up". they just stop working. a more likely suspect would be something in the fuel pump control circut, such as a relay, maybe corrosion or a loose connector. or, as you mentioned, the pcm itself. be sure to check all major grounds, g110 is located on the drivers side body mount just behind the front tire. take both of those ground cables off and clean any corrosion off the terminal and the frame, cover em in dielectric grease and reinstall em nice and tight. that ground used to be the cause of numerous electrical gremlins.

Fireman31 Posted July 7, 2009 Report Share Posted July 7, 2009 Check all of the grounds, but if they are okay, I would look at the fuel pump next. We had a similar issue here at work with an '00 Express, turns out the fuel pump and sending unit were going bad....... Quote Link to comment Share on other sites More sharing options...
