how much pressure does the pump make when you pinch the return line?
you should be getting in excess of 80 psi , and if not the pump is tired

 

ok thats what im saying. prime them so you get fuel inside . then try to start it. see if it starts

 

oh she is starting but the second that the motor sees some load it will buckle and die

 

sounds like your maps got tweaked somehow.

 

Karack will you look at my map if i post it and give me some pointers?

is that a stock t2? 550cc ?

 

delete those RPMcruise figures, not sure why people wind up with modifications to those maps at such low RPMs.

if the engine just came out of storage, vacuum may be low which it may be tweaking the fuel maps with light throttle inputs because it meets the peramaters for cruising situations which are overly sensitive on these ECUs.

cruising maps should only be touched in the 3-4k area.

also bump your Pump1amt to 10 maybe even a little more to 15, with it at 0 you have no accelerator pump at low speed tip in.

 

half bridged S5
72mm ball bearing 1.15 divided ptrim
720cc 1600cc injectors
aeromotive fpr parallel system
2 in tank walbros
-AN lines from the tank 2 the front
aeromotive fuel filter

 

Vacuum is 14 at 1480 rpms(bridgeported motor)
and im bumping the pump1amt as we speak.

 

also try shifting the REVstage figures up if nothing else helps, that will give you an idea if you are having a primary/secondary injector bank issue. you're basically running a non staged setup with all 4 injectors firing as soon as you are off idle. shifting it up will run off the primaries a bit longer until the stage perameters are met, if it constantly stumbles when it gets to staging then you likely have a stuck secondary.

 

I did play a little with the staging last year when the car was running fine and it did not work,horrible backfires and bucking at the staging point. Thanks for helping guys

 

i am installing my other set of injectors and see if your hypotesis of a stock injector is truth!i hope your right Karack!thanks buddy

 

Have to have some sort of hardware issue. when it does start and idle does the map sensor read vacuum and flucuate? have you checked to make sure your injectors aren't full of crap from sitting. try taking them out and blowing some brake cleaner in them.

 

they do look clean and there is no crap clogging the system
Map line is connected and vacuum does bounce around a little cause is a bridge,i wish a have a video camera so i can show you guys that it does idle great but the moment that i go on the road it just buckles and is doing it on vacuum and when i get close 2 zero on my boost gauge

 

Try to play with the mix trim to see if it helps.

 

Did not help
Waiting on a new air intake temp sensor and a new aeromotive element for my fuel filter.

 

Over 90 but it did bounced a little between 85 and 85 after a couple of seconds well my battery was a little tired 2.

 

Cause my FD is doing the same thing(ran fine before) I add 15% mix trim and it revs good so far. Now I know it is fuel related, going to remove the fuel filter to see if it is the problem.

 

try to make a log of it idling then do a tip in to get some values of the injector duty cycles to see if it is in the maps somewhere or if it is a hardware issue. if the duty cycle dips, then it's likely that the way it's mapped is causing it.

 

Karack here is a log file of the car idling and me tapping the pedal.
Also i did floor it twice and no good.

 

What the FUe#%,I just took the car out for a spin and it drove fine and the only thing that i replaced was the air temp sensor..................weird ****.

 

yea, it sounds strange. i looked at the log and it looked fine but almost sounded like a 2k rev cut but was not displaying any sort of cut out, rest of the figures all looked ok.

if it happens again try physically resetting the connection from the car to the ECU by disconnecting all the plugs and plugging it back in.
