Another Alfa, I hope.

I can't believe you're giving up on this thing, man. You've invested a lot of time and energy into it. Seems like a rash decision based on frustration.....maybe sleep on it?

I'm sure it's a great deal for someone.

Good luck.

Slew...you have no idea how sad I am ...but i have hit wall after wall and it's no more fun...someone else who knows Alfa better than me will have better luck...

If no one buys it, I will still try to figure it out.....

 

have you tried putting the engine on an engine dyno and troubleshooting it that way, as opposed to in the car? Also what ECU are you running, maybe another brand?

 

It's not the engine as i have exactly the same problem with two different engines....

It's not spark as that system was entirely replaced with a stand-alone system

It's not injector control as that system was entirely replaced with a stand-alone system, too..

Only thing left is fuel pressure/pump circuit....will hard wire to battery today and see what happens....

 

When you swapped the engine did you take any parts off the engine that came out? Maybe a bad part got migrated to the new engine? I'd also check all the grounds to make sure they are tight and not corroded. Have you swaped the computer yet...could be a million things and I'm sure you have looked a million times for the issue. I'll bet it's something silly and is looking you right in the face your just frustrated that you can't find it. Try troubleshooting from the beginning and toss out what you "think" you've checked...you have done too much to turn back now and admitt defeat. The car looks great!!!

 

It sounds like you have it pretty well narrowed down. If it were my car, I would replace the fuel pressure regulator and hot wire the fuel pump, via an in car on/off switch for diagnosis purposes.

Greg,

P.S. that's a cool car, I saw it in person a few years ago.

 

There should be some sort of diagnostic software you can plug into the ecu while testing that will record the signals and help you trace the bug. It must be some sort of dropped reference sensor or something... What car could possibly replace that one?

 

Thanks fellas! There has been some interest in the above items so I am not sure how much more I want to do.

Bosch system/ECU has no diag plug, and I have tried 3 different 3.0 ECUs and an entirely different engine w/new injectors and regulator, noid lights always worked.

May sound silly, but the only thing I have not done is hot wire the fuel pump.... it's the last thing I can think of and if it does not work, I will probably lose it!

 

I would think about converting to standalone such as gotech or megasquirt, then watch the curves through acceleration, find the area [about] when it sputters (not necessarily why) and then use the programmability of the ECU to counter/cover up the sputtering. By adding a reference sensor, or changing the sensor loop and how the ecu determines timing, mixture, spark, waste, etc. you might be able to fix the problem.

P.S. I like the chrome bumpers, any more pictures of them?

 

Yep...already put in a stand-alone...a Haltech 10 to run the injectors, fired right up on first try...took it on the road and had the hesitation....took out haltech and put back the Bosch control and the same thing...this was a real pain by the way..

For anyone interested: Haltech not included in sale price...going into new car...unless you want to add antoher 800

 

Where are you located?

Michigan, 30 miles west of Detroit

PM me for more specifics.....

 

chrome: I have front and rear , front mounted only, needs some final touches...

Additional items: several sets of tailights old style including one complete brand new matching set from Re-originals; 'new' rebuilt 90 amp BMW alternator (makes everything bright!!) ; european chrome mirrors with thick stem and Alfa logo to replace electric side mirrors( was going to paint car red...and i think red goes with chrome real well); BRAND new 800 amp cold crank battery put in last week (NO trouble cranking over those 10.5:1's in freezing Michigan weather)...and much more..

sight to see and hear: Includes a short run down the street, reving the new engine, mild lumpy cam idle, and front turn signals....

Rather than hot-wire the fuel pump and hope for a lack of problem, why not instrument the fuel rail and read the pressure? This would indicate when the failure occurs whether the fuel pressure is sagging. Other solutions exist.

xtrad.

cool looking gtv6 with the pre-black out window frame look and 2 piece tail lens. was it hard to put the older alfetta gt/spv brightwork and rain gutter in? the gtv6 rain gutters ran to the rear 3/4 vents i assume to hide the seam welds.

great lookin project, too bad you cant keep it. best of luck with your sale

D

 

I think I am pretty much done for now with this project......much of the chrome came with the car...It was on a real us stamp in Texas so I guess it was special at one time....

 

xrad, what do you mean it was on a "us stamp"?

Greg

 

Greg;

I mean 'this car was on a postage stamp' a real legit US stamp at 39cents

This is a one of a kind Alfa....

of course I removed the black bumpers.....still have them, though

 

Now that's cool!

 

You can do that with any picture. Go to stamps.com and you can upload a pic, choose a denomination, pay online and they will send you a block of legal U.S. stamps. I do it for holidays and announcemnets like weddings and such.

 

yeah but his says honored marque...

 

The pic for the postage stamp was taken at the first ItalianCarFest in Grapevine,TX when I owned the car. My son Jake and I are sitting in the background. I bought the car from a guy in Trenton, NJ and drove it home to Texas. Great drive!! The rear lights had already been changed out to Alfetta lights. I don't think it's that difficult of a job. The car already had a 3.0 Verde engine in it, and the front had been lowered. It has really undergone a transfromation since Fred got ahold of it. I hate to see that you're giving up on it.

Later, Steve

 

HEY STEVE!!!

why are waiting in the wings??? Yeah, your car is awsome and I have busted my *** tying to improve an already great Alfa (tastefully) Well Don't worry, it has not sold yet and maybe if I am nice my wife will let me keep it and the new car ......


where were those rims?????

I have taken good care of her...especially the engines!!! When she runs, she is very very fast!!!

AND NOT EVERY ALFA GTV6 IS ON A STAMP!!!(as an honored marque)

PS: pic of maybe new auto...

 

wazzat?

PS: pic of maybe new auto...

Hey, way coo'..... I didn't know they still made Studebakers.

 

In all seriousness, what kind of vehicle is that? I like it, in any case. Could you please provide year, model, etc.?

If you keep the GTV-6 (and we all hope you do), Xrad, follow the advice from Greg, his trouble-shooting is often spot-on.

Thanks.
