As some of you may know I have been having some real problems with start up on my car after it sits for a few hours. :?

-The alternator/battery/starter are very strong
- Lots of pressure in the fuel lines
- Strong Pump, charges and sends no problem
- No Driveability issues...runs smooth
- Premimum fuel only (i only go as low as 89 octane)
- Replaced fuel pressure regulator

Today I went for a complete fuel injector conditioning, I will keep all of you up to speed on the results of that

:?

Well the ultimate elimination challenge is tomorrow morning, since i had the injectors cleaned it runs WAY better, not like it wasn't fine before, now its just better

We'll see tomorra

Well, I give up, I'm fresh outta money and fresh outta patience, or maybe I'm just grumpy this morning, but, alas, same ol problem.

All I can do is chalk it up to age

Hrm... Our yukon had a problem where something cracked, and i don't really know what it was cause I didn't know much about them at the time. But it cracked and the car would sorta flood itself i think when it sat for a long time. After about 5x cranking as a new car, it would go. Is your block/intakes good? Check your plugs recently? I know my car has the timing controlled by the computer, but when below 400 RPM (Cranking) it is controlled by the engine itself. Or something along that lines, it'* been a while since i've looked at it.

Will do Don, however, the crank sensor has me thinking. Ok, no codes, but....is that possible?

Good thing i posted that eh! Good to see you got power again Jimbo!

Oh I will be getting on this...its rather embarrasing to have this car struggle like this to get going.

Don we will talk about this futhur...

Just let us know what'* going on!

My money is on the TPS!

Hey guys, thanks for the credit!!!! Now i see why you're mods, you make yourselfs look smart!
