Fuel Problems

[NewGen]

Alright I resently purchased a 1988 toyota supra 7mge. It hasnt ran for 2 years. We put a new starter, plugs wires, Intake manifold gaskets, New battey, fuel pump, fuel pressure regulator and we have the fuel pump relay bypassed right now because its bad. The car will start and idle fine but as soon as you lay into the gay at all the car will instantly die. Does anyone have any idea on what it might be?

How did you determine the fuel pump relay is bad? Have you checked for error codes? Tested the AFM?

as soon as you lay into the gay

Wow... now THAT's a typo!!!

Hope it's a typo

I'm sure it is... if it wasn't he'd be bragging about how his MKIII was the lightest MKIII on it's feet and complaining about the flaming tailpipe. :evil2:

If you need a new one, I've got a couple of them. $15 shipped.

Now, about the fuel pump relay........Fix it, don't just bypass it. These cars don't appreciate band-aids. I probably have one of these too.

lol I have a turbo supra this cars actually my cousins so bare with me I know how tempermental they get. Any change a 5m maf will work lol

 

[CRE]

Any chance a 5m AFM will work lol

On a turbo MKIII? No. It would probably *work* on a N/A, but the airflow scale may be off.

 

[NewGen]

K, because i have two 5mge parts cars. I'll probley just pull one of those off just to try

 

[NewGen]

Checked the maf it was fine, still swaped to the 5mge maf and it didnt help at all. Any other ideas?

There are a few other valid considerations mentioned in this thread which you haven't acknowledged checking... So, if you would be so kind as to recap precisely what you have tested it'll make things a lot easier for us to help you.

 

[NewGen]

Replaced fuel pump, Fuel presure regulator, Fuel pulsation dampiner, Tested fuel pressure and its fine, Swaped mafs. Thats it. Its not throwing any type of code

Have you checked the timing per TSRM? Did you check the MAF per the TSRM? Sure you don't have any vac leaks, air leaks around the MAF or TB? If it sat for a while changed the fuel?Compression test?
If you post back and say "I think it"s OK, or it should be alright" there's going to be a few that will be done with this thread, me being one

wow since when did everyone on supra mania turn into an asshole... I'm not even gona bother its not my car anyways... By the way its common sense if the cars sat for 2 years to drain the tank and replace it and all the above has been done thought that was just a standard tune up...

Did you post that? Also common sense to check all the things I mentioned, you should have said what you've done and what you haven't. Not trying to be an asshole but if you don't give us something to go on we are just guessing like you are throwing parts at it.
