Snider, you're trying to just rush through this and throw parts at the problem, and that may or may not actually fix it. And, unless you get really, really lucky, and throw exactly the right part at it, you're going to end up spending a lot more money fixing it than if you take the time to actually diagnose the problem.

Now, if you want to just throw a rebuilt TBI on it (and for $50 it's probably a lousy rebuild from Autozone) then go right ahead, and good luck to you. Your money and your vehicle, and no one here will deny that that is your right to do.

But, if you actually want to understand what's happening, find the exact cause of the problem, and fix it correctly, we're all willing to help you do that. The choice is yours.

Now, the CEL is an important diagnostic tool in situations like this, so having it working is to your benefit (not to mention an automatic "fail" if it's inoperative in states and areas that have emissions inspections), but if you don't want to bother with it that's up to you.

How are you checking for "spark" at the injectors? (Please don't say you're shorting them out, grounding them, or anything like that...)

Okay, that whole "spark" thing just brought up a mental picture of you holding a bare wire from the injector near a ground to see if it had "spark". Not a good mental image.

You can use a test light to see if it's getting a pulse, or buy a "noid" light to check it. Most likely though you're not getting a signal to the injectors due to a bad sensor or ECM.

the ecm is a chip right? ignition control mod? or its a sensor.. well i guess tomarrow i will check to see if it has a pulse if it dont ill start with the ecm or the sensors?

BernieB · 10-25-2009, 12:29 AM

ECM = engine control module

BTW, I did some looking and I can't figure out where you got that $50 price for a new TBI from. You can hardly even find a single cheap injector for that price, let alone a complete TBI.

snider777 · 10-25-2009, 12:32 AM

budget auto wrecking lol. if i take it off my self he said 50 bucks. where is the ecm located and some the most common sensors to replace?

snider777 · 10-25-2009, 05:47 PM

yeah i need to know wherew to find the ecm and how much they run about? or where are some of the sensors i should try to replace
