Starting and gearbox problems with supra Any Help

[trd-drifting]

OK ive just turnd 17 and i know a little about cars. I brought a Ma70 (7M GE) supra which had no running gear ie driveshaft gearbox clucthlines pedal etc... now i have fitted a w55 made a drive shaft from an auto and a manual shaft. A few days ago i had it on axle stands and it reved fine and responed well. I drove it with no clucth (no lines and clutch not bleed hence no clutch) down to a pit 2kms away it went fine but as i got there it startd to run out of petrol. Now if you run a car out of petrol that is injected you might get air in the fuel lines i take it. I have now finshed the clutch and it works well and engages fine.

First Problem.....

I tried to start the car and it fires and you pump the acclerator and it fires and then dies. It managed to start and i drove it home and only got about a km before it died on me again, when i was driving it there was no responce with the accelerator with my foot flat to the floor it took like 5 seconds to rev up to 3grand and wouldnt rev past there and if i went into third gear or any higher the revs dropped and dropped. Now would this be because i have run the car out of petrol and there might be air in the lines (just guessing). It just sound like the car is being starved of gas. The more you pump the pedal the longer it goes but does fire as in start properly. I take it the fuel pump would be fine etc... Any ideas.... Would you have to bleed the fuel lines or something.


Second Problem
Now when i was able to drive the car before i ran it out of gas, there was a slight noise coming from the box it sounded like a stuffed bearing or metal rubbing lightly etc... Now i no the spigot bearing was fine the realease bearing is new and the clucth works well and engages fine now (noise is still there being towed in nuteral ). What could this noise be, any ideas ... also as you incerease the revs while driving it starts to get louder but it is not all that loud. Now i have no idea how gear boxes work but i take it there has to be bearings in there could it be a bearing in there proberly. Any ideas just say please......



Hope you could read all this any help would be good

In the box, it possibly may be the imput bearing...pretty hard to say via interweb however. That seams to be the one I replace the most often on cars anyway... Dose it still make a noise when the clutch is pushed in/disengaged? (im assuming not), but with the engine running

Replace the fuel filter etc at all?, may have clogged up if the tank was particularly dirty when you ren out, although Im skeptical on my diagnosis there. Also, are you using new fuel, or just old junky stuff?

You would have got a bit of air in them, but virtually none once the car is cranked as the fuel is delivered at presure to the injectors as soon as turn the key.If it was a diesel it would be a different story.

Also could be a bad alt/battery which caused it to run & stall etc. It'd pay to check those also. I had a similar problem with my alt failing on the Ga70 once, started running like shit for about 5km, then eventually died.

The fuel in it is from mobil, mind you it is only 91 octane and it would be better to put 96 or 98 in it. I rang my boss and asked him and he said it could possibaly be som rubbish or sumfing in the fuel lines or filter. I brought it and it had not been turned over for about 2 years and it turned over first pop with the left over fuel in it so that might have been the casue of the problem.
Well when the rain stops il go take a look and replace the fuel filter etc..

At a suggestion i'd say that you may have sucked your fuel filter into your fuel rail and/or got it lodged somewhere less than desirable when you ran it out of gas, happens if ur filter is old.

Climb under ur car, take the fuel line off the bottom of the engine (it'll have a banjo bolt attaching it to another pipe which then runs up the the rail.) and get someone to try turn ur car over, if everything is right with the pump etc it'll spit fuel into ur face (great fun kids!) if ur pump is all good, check the filter, its up above the D/shaft, so u have to take that out to get at it. replace it if its stuffed etc. etc. (what i had to do with my GA-70) then you have to find the bits of ur old filter, (if that is ur problem)

you can replace it with the shaft in place, pretty tight job either way really...terrible placement for a servicable unit.

Ok I have replaced the fuel filter (Its in the most stupid place to put a fuel filter to replace lol) now the car stil sounds like it is only running on a few cylinders. Now is there only one fuel line that goes to the manifold/injectors, becasue i took a fuel hose off underneath the manifold and placed it in a bottle and tried to turn it over and nothing came out of the tube. Now would this be normal or not and since the car still just turns on and runs i take it there is a second fuel line like that. Now im going to check the fuel pump tonight, but any other ideas that might be wrong with it please say, so i can check that off.

Please put you 2 cents in as 2 cents is better than 0 cents.

Ive heard of furl pump/pump relays on the ma70's playing up now and then- turning on and off, so it could be a possibility. As I recall (which is vague) the main feed to the pump looses power.
The main fuel in will be at the end of the fuel rail attached with a big bolt
