i took at my injectors and put them in a new top TBI unit. problem.. i start the car, fuel comes out of the side of the top of the tbi unit and not the injectors, did i put the injectors back in the spot in a wrong way?

 

unsure what's going on here... did you clog them? are the fuel lines on correctly ?

 

i dont think i could clog them, i think maybe i set them in a wrong way, i wish i knew the way the fuelflows throuegh the tbi, but anyways im gonna rotate each injector 180 degrees and try again

 

There should be a roll pin in each bore of the injector pod to locate the injectors properly. Make sure yours' are in correctly, and inspect the pod cover gasket closely for defects.

 

ya im trying everything, and no luck, the fuel sprays out at 5 different locatotions at the gasket...

and what is this roll pin u speak of? got a picture? or draw one?

i did notice behind the little filter on the injectors, their are 3 holes, i lined one of them up with the side of the TBI where i believe the fuel enters...

im soo mad

 

ok well i am gonna swing by and by a ne gasket set and see if that does the trick.. but i also would like to know if ANYONE out their knows exactly which way the injjectors fit in so i dont screw that up either.

 

2 words my friend... o rings... the big rings that are rubber crack into a millions pieces when ther hit air for the first time in years after being submerged in fuel their wwhole life.. take your injectors out again and buy a TBI rebuild it and you get the big o-rings, little ones for the bottom of the injector,, anbd the little round screen thing that goes at the bottom of the injector as well... plus you get new gaskets with it and a spacer as well worth the 20 or so bucks...

i took my injector out as well and got the same exact problem.. top of the injectors were soaked and car would barely if at all stay running hope this helps

 

no thats not the same problem as me, here is a pic i drew, if your looking top down, the green is where the fuel squirts from.

now i knowthat fuel comes straight up in the center, then it hits the top of the TBI and runs off down the left and right to the injectors, but it seems the gasket right their doesnt hold anymore and when the fuel gets under pressure, its blowing out right their at the top. make sense? if not the pic should help.

 

well i went around town and no one sold just the gasket, so i boulght a rebuild kit for 33 bucks, will be here in about 4 hours they say.

 

The pins at bottom of injectors, there are pins sticking out one side - if you look down inside TB unit, there are recesses that these pins go into to get the injectors in correctly. There's really only 2 ways to put the injector in. If you draw an imaginary line from frt wheel to frt wheel, the electric prongs on top of injectors line up with this line - therefore only 2 ways an injector can go, with the pin (the pin on the bottom of injector) towards the firewall, or the pin towards the front of car. And, if I remember correctly, one injector goes in with pin towards firewall, and other goes in with pin towards front. I've also seen new replacement injectors, that don't have 'metal pins' but rather little plastic nubs on the bottoms - but same thing - they fall into a recess in the bottom of the pod.

The $33 rebuild kit should be right - I remember it being bloody fortune too, but should have the pod cover gasket, the little round gasket to the pressure reg (don't forget this one, it's easily lost), and both o-rings - the small o-ring for the bottom of injector, and the large o-ring for the top.

 

cool well i have to go pick it up now, will b e back later with results.

 

gasket worked, fuel runs fine now. case closed
