Finally got to drive the bird around

[2.8 Bird]

I got it smogged today, but it failed because I haven't driven it in awhile and plus it has a new battery which affected their smog machine from getting a reading of the stored code. So I have to drive it around.

Today in Nevada it's a 120* and my AC wasn't working. Actually the belt would slip really bad from the AC compressor. I have the double sided belt for my supercharger. I'm thinking of going back to single side belt. AC is a must where I live.

Also, this has been a problem I've had for awhile. I have no problem doing cold start, but once I turn off the car and try to do another start after 30 to 40 minutes or so the car has a hard time firing up. I noticed the FP was low. I already changed the fuel pressure regulator on this and it's still the same. Any suggestions.

Do you have a walbro 255 fuel pump in there? Or is it stock? Still looking good.

[2.8 Bird]

Yes, i have the walbro 255. I'm thinking of changing that. Would you recommend that same pump.

I'm going to change the ect and see if that's the culprit.

[ssms5411]

Whats your fuel pressure at idle? Then at WOT? Ect wouldn't have any effect on the fuel pressure. Did you do the trap door method? Yeah I would do another Walbro 255.

[2.8 Bird]

I saw 38psi. No difference if it was open throttle or not. Awhile back it was 40 to 42psi.

I do have stock injectors and I only have the vortech FMU.

Yes I did the trap door awhile back.

[LETZRIDE]

That is low fuel pressure - how old is the pump?

[ssms5411]

Yeah thats low, I see 44 psi at idle and 48 psi at WOT, maybe time for another Walbro 255, Im at 16-17 years on my Walbro 255.

[2.8 Bird]

Yes, about the same years as Steve. I've had ot since 2002, same time as my supercharger. I'll get it changed then. Do you guys still recommend walbro or is there a better one.

[ssms5411]

Also you need to ditch the fmu and stock injectors and go with hptuners and 36lb injectors(33lb) on our system. Then you can ditch the trc-1 timing controller and just use hptuners to dial in your timing. Just a thought. Also do you have a wideband O2 to see if your running lean?

[ssms5411]

Just thought about it and your fuel pressure should be in the 90's or over 100 psi at WOT since your using a 6:1 fmu bumps your fuel pressure 6 psi for every pound of boost so your fuel pump is toast if your not going over 50psi at WOT.

[2.8 Bird]

Good info there Steve. Thanks

Yeah, since I don't live in California anymore I can ditch the soft tune. Yes, I do plan on getting a wideband.

[2.8 Bird]

So are you guys using the bucket where the fuel pump goes in.

[ssms5411]

I ditched the bucket and used hose clamps to put it together. Just make sure its tight, when I first did mine the hose came off and had to go back in, thats why Im glad to have the trap door.

[2.8 Bird]

Alright. Thanks
