I have a 1999 Chevrolet Suburban and occassionally (every few months)when I go to start the vehicle it starts and cuts out immediately.  I'll let it sit for about 20 minutes or so and then when I go to start it...it starts!  I've also already changed the fuel filter.
I've read a recall regarding fuel pump problems with 2000+ Chev. Suburbans, but not 1999.  
Other than the occassional not starting, it runs fine.  Any ideas what could be the problem?

Hello JLT,

Has your problem been solved?  I don't have an answer but I can tell you what we've done to our truck which seems to have the same problem.  We have a 1998 SWB Z71 truck.  I realize there's a difference in year/body style, etc... but your problem sure sounds similar.  We took our truck to the dealership.  They didn't find problems with the fuel filter or pump but said the ignition/passlock systems were throwing codes so they replaced them both.  We already knew the security light would stay on sometimes.  But no luck, we're still having the problem (including security light sometimes) and now no codes are showing up.  Our problem seems to happen early in the morning - maybe moisture in the air is a contributor?.  Won't start, wait a little while and then it will.  It is VERY frustrating and seems to be getting worse.  We keep taking the truck back but of course the dealer can't reproduce the problem.  If you found an answer please share!!  We will do the same.  Thanks and good luck.
