Quote from: 1trucavalierwhile your at it whats the part # for the stock injectors?  I went to pepboys and they told me they were $27ea as you imagine i quickly excited the building!  

Exited maybe?  :wink:

Don't bother trying to get them "fixed" I can almost guarantee it won't work. On the flow bench it may look ok, but they CAN and WILL still cause problems in the car. I've been there done that, just to prove it to myself. I think the last price I got from Jeff was around 80 or 90, they are not a common injector, but if you want it RIGHT its what you have to do. I also wouldn't recommend replacing 1 or 2 injectors if you are expecting any kind of performance. If you have an injector failure, save yourself the trouble and just get 6 of them.

Also, aftermarket brands have not had the best sucess in the TGP. Ones that the parts counter would sell. Like many other parts house parts, the have a LISTING for a TGP, but it ends up being the same part as for the NA 3.1. Even still for the injectors, I think the part number was different, but the injector wasn't appropriate for the application.

The fuel pump pulsator is used to take the pulses out of the flow of fuel. Not sure if it will affect the performance of the engine at all. On my swap I used the stock fuel pump out of a 1994 corvette (not a zr1 model) that has the same psi rating and physical dimension as the original but flows at 38 gph. not sure what the stock rating was but I think it was @ 20gph.

dealer price is $85ea.  If they are prone to fail then I just can't see buying new ones.  I am just going to take a chance with accel.  Mine are leaking now.

Here's my input to this subject.  THe replacement or aftermaket injectors might have different resistance than the oe TGP injectors even though they have the same flow rating. That might be the cause of poor performance by those replacement units. And if you use low resistance (10ohms or lower than the TGPs--forgot what the TGP  ohms were--listed somewhere in the TGP forums--)injectors, They might heat up and loose acuracy. The computer can drive high resistance injectors at full capacity. Those low ones will reach their full duty cycle very quick.

They are listed as gm multec injectors correct?   I was given the impression that all the gm injectors (older model gm) had the same type injectors (ohms/size) just different flow rates.  21lb, 22lb, 29lb etc........

:evil: After going thru 3 fuel pumps in 14 months (covered by mechanics warranty) I started having 'fuel pump' probs again.  This was rediculous!  I had asked if there was an electrical problem and my mechanic said no.  The last time I had a prob, I 'wiggled' the fuel pump connector.  The car started.  I had to do this a few more times.  When the weather gets warmer I'll be replacing the connector!!!  13 years of weather can corrode electrical conections!!! :lol:
