A1 is showing 11.5 volts for 2 sec prime cycle. And then a delay for 10 before it will prime again.

 

That is working properly, The only other thing maybe the pulse damper is leaking or the pump does not have a check to prevent the fuel from staying in the supply line.

 

Big improvement today the car would hit hit and hit but just not fire off.... Reset the timing, distributor and all. Even with starting fluid it would only hit. Still having fuel problem

 

Will the car start with out the ecm controlling the timing?? It keeps hitting over and over just no start yet.. still not starting off the starting fluid.

 

with the ecm removed from the picture you distributor is just set at base timing.

 

Make sure you set timing to 6 degrees before tdc with the est unplugged if yours has one. My 91 had the same problem and I found the map to be bad but mine is speed density setup. If it helps I'd change the fuel filter as well. Mine ran like crap until I did that and it was a night and day difference

 

Full turn up done all fluids changed, plugs,wires,filters,all have 100 miles on them before this happen

 

What I thought atm It's set at 0

 

with the est disconnected it will be 6 dbtdc , once you connect the est most tpi programing will advance 6degrees so it then would be tdc.

 

Yea seeing I've been wrong before... I'll double check with ya my timing marker has 3 marks where would be 0. I only cause I might have set it way off... It's set at the middle mark.. might be why it'd just hitting and not firing... LOL

 

will a v8 fuel pump give my v6 2.8l 89 firebird more hp ???? or make it go faster?

 

 

Yep bout 30 HP

 

you just need bigger injectors to go with it

 

Yea with a v8 pump u need #44 injectors to really see something tho

 

.. ok now that I've had my Fun with this troll... I really won't care if some one had a fuel pump problem post here asking a question but really? Will a v8 pump make my car go faster.... Wow... Put down the wrench Boy it don't belong to you....

My base timing is set at 8 so.... With the info you gave me with the ecm unplugged I'm at 2...

 

with 80#hr injectors you may snap your drive line like a twig

 

ROFL and that's my favorite quote.. going in my Sig so don't move

 

I'm going to have to reset the timing tomorrow... To dark to mess with it..

 

thats a great idea ... When i stabbed my dizzy i did notice its not set towards the number one but more straight down the middle. Dont know if that applies to you but for some reason its the only way mine will wanna work..

 

I'm gettin tired of this car... I've got 10 days to get it running or get it to the shop... My landlord don't want it sitting anymore..... Got a few friends coming over Friday if that don't work then I'm goin to be lost... Gotta come up with the cash for the shop or It's going to get towed...

 

- If the ECM is seeing a high TPS voltage it may be in the clear flood mode. Diconecting the TPS will allow the ECM to use a default value and turn the injectors 'ON'. If the TPS ground wire and connections are OK the TPS should be replaced".
Pulled from another forum tunedperformanc wanted to know what your thoughts on this are

 

In post 59, if you set initial at 6 then the computer adds 6, you'll be running at 12, not at 0. This is fine, on premium fuel or with low compression. Post 66 is correct. I'd advance it a bit more until you re-connect the computer.

 

I can't recall at what voltage it will cut them out I think it was 4v or close to wot, but with a noid light you would not see a injector pulse.

 

Well that don't fit my problem......

 

My bad base timing is set at 8

 

now thats thinking with your dip stick jimmy !

 

Lol just found out we are having a baby boy I'm done thinking with my dipstick......

 

 

Alright tunedperformanc we have 100% confirmed fuel pressure at 35-45 psi at crank jumps back and forth very fast..... At prime I have 45 psi... Jumping the relay we have 45 psi. Now the pressure drops like a dam rock soon as I let off the key or relay. The gauge I used was tested against 2 other gauges. It's on the money......... Wdf........ Where do I go from here.. timing is dead on now still no start even with starting fluid.....

 

if the pressure is dropping right away you have three place the fuel can go, one back through the pump, two though a stuck injector or injectors or thought the regulator diaphragm. I would let it sit over night and prime it up a few time without starting it. then pull the plugs looking for wet plugs. if none found pull the regulator vacuum hose and check for fuel. if those both check out I think your pump or damper is bad. hope that helps .

 

would someone please give me advise i am new to the site and not really sure how to use it yet dont even know how to post a thread and need some answer to problems im having with my 305 tpi just put together and put in car cant get timing to stay in one palce running rich back fires through throttle bottle if i try to drive runs ok for a min the falls flat on its face

 

Dude... If you can post a reply I'm sure Ur smart enuff to post a thread... If u where having fuel pump problems.. then by all means post a question here but u got timing issues I did so much reading before I posted May thread I could have wrote a book on tpi fuel systems

 

is this like a stage coach robbery, how many times do you need to get high jacked bro !

 

indeed hijacking sucks. sorry to hear about your prob Kyle but tuned pretty much knows what hes talking about and i agree with his diagnosis. Hopefully for you its not your injectors because they get expensive a damper or pump is so much cheaper...

 

Lol guns ablazin come get to some highjackers. I really don't mind input to my problem or if they read a post we have made and want someone to explain in detail for them so that they could fix their problem. That would be great in my book, but to come on here with will a new fuel pump and HP to my motor... Or hey my timing is off and I'm to lazy to start a new thread and explain in detail what i have done or tried is bs.....

But anyways back to my problem would anyone of these leaks couse the car not to start seeing I have confirmed the fuel pressure is good??? The tuned I got some work for ya if your up to it I still have the tag in my center console want to know if you will decode it for me? I've found out I have a posi rear end and some other things from it already but some of it I'm not sure what is.

 

Well fuel pressure regulator holds vacuum. Been holding for 10 mins not moved at all.. calling it good.

 

What about your injectors? The drop in fuel pressure would cause it of course not to start. Either it'd being starved or it getting flooded. This is this a maf setup correct. You've confirmed all your sensors are good and plugged in...

 

forgot to mention I ran across this years ago. if you prime the fuel rail and clamp off the return line. if the pressure holds the regulator seat could have a small pit in it. rare but it does happen.

 

Well..... It runs fired off and ran like total dog shot for a full 30 sec timing is off..... The fix was new plugs the first ones where gas soaked. Love my part guys they switched me out plugs to entertain a idea one of them had...... I put 4 in and was like I just did this ****.. no way It's fixing it.. well she cracked right off and ran....

 

Map sensors is junk... Gotta replace it. I primed the fuel rails with the pump and clamped off the lines it held pressure for 30 mins

 

think thats your problems solved right there bro... thought it had something to do with the maf...

 

map sensor the 85-89 tpi camaros use maf

 

i said maf didnt i?

 

wrong thread sorry kyle dont wanna hijack you again... lol

 

whats was thier idea? Also i thought if your spark plugs were soaked in gas you had a bad injector.... am i wrong in that assumption?

 

And I thought this was a thread about fuel pump prime

 

Dude this thread is done now... Idk wdf happen... But it went from no pressure to spark plugs in a month long I'ma goin to pull my hair out. Wdf Is wrong with this car... Let the highjackers come now I'm done with it car runs and I'm happy thank you all for the help.
And I had put new plugs in the car but some how they got soaked in gas so I replaced the plugs with 100 miles on them. To new ones that have about 30 mins of idle time. New plugs fixed it

 

glad you got it going, and didnt spend too much coin. atleast you have more experience on tpi than you ever wanted.

 

I love this stuff. When I pick up a wrench to work on something, the crying kids the fight with my wife all seems to disappear. Me and the car that's all I see and tho its frustrating as hell something's I enjoy this the most. My kids and wife are 2nd to nothing in this world but the Passion I have for working on cars and seeing something run again, It's right up there with them. So learning about tpi systems wasn't that bad.
