tbi problem

[savvyaggie]

Ive been working on the Jeep the last couple of weekends, new throw out bearing, u-joints, etc. but now I have a new problem.


The last couple of times that I started it, it was running REAL rough. It wouldn't even idle. Sharpe came by and checked the codes and there was a bad temp sensor. I was fixin to leave to get the sensor, but today I started it again and noticed that only one of the 2 injectors are firing. Is there a way that I can test it it see if it is getting signal or to see if it is clogged up??

did it sit for a while? tap the injector with the handle of a screw driver. it'll start working again, probably.

[savvyaggie]

it sat for a couple of months.... I already tried that with no luck....

[agjohn02]

tap harder?

[savvyaggie]

hehe... I did, trust me....

[agjohn02]

not sure about TBI but most FI systems can be checked with a noid light. pretty sure you can borrow them from the parts store and plug it into the harness. if it flashes then the signal is fine.

[savvyaggie]

It is the injector, I crossed the plugs, now I just got to get it unclogged!!!

[agjohn02]

soak it in berryman's then tap HARDER:)

[savvyaggie]

i just took it apart, and got it unclugged. So now I have a new problem, its now putting out to much fuel!?!? :mad:

[savvyaggie]

Im fixin to head over and just get a rebuild kit for it.

[BMFScout]

it won't rebuild the injector, it's just seals and ****. I've got some extry injectors, send me your address and I'll mail you one?

[savvyaggie]

Cool, thanks...

[savvyaggie]

Let me mess with it a little tomorrow first, I think a little trash got in the o-ring groove. If so I should be fine, if not I will get the injector from you...

[Sharpe]

I have a couple of 5.7 injectors I'll throw your way if you needum. I can getum to you early saturday so lemme know asap tomorow.

[savvyaggie]

It looks like I will be needing those injectors.....

[BMFScout]

The 5.7 ones are probably too big, I've got some out of a 4.3. It may not matter, a 5.7 one is probably better than a fawked up one. I'm not doing anything with them, PM me your address or post it here and I'll mail 'em out tomorrow.

[Fredo]

isn't that nick's old jeep? 4.3? Yeah, I know we've got a couple sets of those injectors sitting around. They are yours if need them.

thanks

[savvyaggie]

yeah its a 4.3, but I thought nick said that he put 305 injectors in it, but I am not sure. I know you can run 454 tbi on a 5.7.

[savvyaggie]

Ill just stick with the 4.3 ones

[Fredo]

I've probably got a set of 305 ones too. If you already have them out, get me the numbers off of the tops of them, or if they have the paint markings still, tell me what they are.

[savvyaggie]

it's kinda hard to read but it looks like GM5235203*rpo (on one side) and 5151 on the other side.

[Fredo]

yeah, those are 4.3 injectors. We'll get them in the mail to you.

[savvyaggie]

awsome, thanks!!!!!!

[Fredo]

there might be a complete throttle body coming to you......if so, just consider it spare parts. heh.

[colman]

i have a good injector in town, give me a call and you can see if it will work

[savvyaggie]

there might be a complete throttle body coming to you......if so, just consider it spare parts. heh.



awsome!!!

[BMFScout]

You owe me one. Not for the throttle body or the postage, but for having to stand in line at the post office. There was this girl in the front with a nice bobo, and I guess it was cold or something b/c she kept shaking it around, so that was some consolation.

[savvyaggie]

awsome, Im sure will figure somethin out.
