I have a 92 camaro 305 TPI..just the other day I installed the bosch III injectors in my car and after the car sets for awhile it doesn't wanna start up like it did before I replaced the injectors..it takes really long to start up and even after it cranks it acts like it's not gettin enough fuel maybe and wants to die..did die once on me but started back up...seems to only act like this when cold after warmed up runs fine and starts fine...thanks for any help wit this prob

you have to do a fuel pressure leakdown check. crimp off the return and put a fp guage on it to see if it leaks down. if it does not, its the regulator, if it does then its your fuel pump check valve, so crimp the feed while under pressure.. shut the pump off as soon as you crimp the feed line// if it holds pressure, replace the fuel pump.. if it still leaks then you have a leaky injector

You can check for a leaky injector by pulling the plugs,, if you have a wet cylinder
then you have a leaky injector. If all else fails, send the injectors to us, we will be happy to
put them on our bench and check them out for you, NO CHARGE!
Let us know the outcome.

I'd overnight a whole new set and put a tag in the box to send them back...

Just a suggestion.

alright sounds good..thanxs...i really don't think it's my FPR cause I just put one on abt 3months ago and the fuel pump is around 6months old or less but I'll check the injectors out....what do I all need to send them back...i ordered them wit my debit card so didn't get a reicpt...or any other papers wit the box they was in

No problem, we would get another set out to you. We leak test out injectors up to 80psi so when they leave here we are confident that they do not leak, but things do happen. When receive them we will put them on the bench to see where the problem is if any.
When you are ready, just contact us PM or call, and we will be sure to take care of it for you.

I just bookmarked your homepage Southbay! When and if I need to replace my fuel injectors on my 89 IROC 5.7 I will be purchasing from your company. When I read your posts about how you would handle lopez's problems with his injectors, you earned a future customer.

southbay08

That's great. It will be our pleasure to do whatever we can for you!

I just installed my bosch III worked perfectly (Southbay). I did have a problem very similar to what you are describing after I installed mine but it didn't have anything to do with the injectors. Check to see if you have a code 54. I had to replace the fuel pump relay.

I highly recommend Southbay and their customer service, very patient with me and answered all my questions.

what problems was you having

Msaby

The engine would have to crank several times before it would start.

How does your oil pressure sender work? This could be the cause or a bad Fuel pump relay. I'd check and/or replace both.

southbay08

you might also want to check all of your sensors.

mine did the exact same thing. had an itermittent code 44 before the changing the injectors, now it runs lean all the time. takes several attemps to crank and have to crack the throttle to crank it. runs like a scalded dog though, just lean. idles great too! have changed everything but the fuel pump and the computer. i am beginning to hate tpi!

southbay08

have you checked your sensors?

turbinator3

until i am blue in the face!!!!!!!!!!!!!!!!!!!!! i am thinking the fuel pressure reg mighrt be leaking. i rerplaced the diaphragm back in the summer, but i can still smell gas in the vacuum line. the pressure with the vacuum connected is only 38 at idle. didnt check it unhooked, but that does seem low. like i said, car runs great. the funny thing to me is that at speed the cel will go off until i let off the gas. then it will stay on until i do a wide open throttle bloop gewtting back up to speed.. seems it should be opposite if it is a fueling problem

well I just tryed to drive it today and it's has no power at all now just bogs down like hell like it's tryna pull at house..i have no codes or engine light on...so I guess I'm just gonna send the fuel injectors to see if they leakin and start there

southbay08

no problem, we will take care of it for you.

Thanks...i guess it won't hurt to send them to yall to check them out for me..so how do I go abt sendin them to ya so yall would know to check them...

southbay08

when you send them, put them to attention Frank. Include a note with your name and your phone number so that we can contact you once we put them on the bench.

turbinator3

did you check the fuses for your injectors?
