ok so i purchsed a 1989 Firebird with the 305 (5.0L) TPI thinking the injectors needed to be cleaned, so yesterday i did that, i took all the injectorwires off. Now my Car will hardly start im almost positive because i dont have the the wires on the correct injectors. Can someone Please tell me which wires go on which injector! Thank You

 

tpi is batch fire. it fires the left bank of injectors together, then the right bank together. as long as you dont have left and right mixed up, it doesnt matter what order the plugs are in.

 

Thanks....So im Confused on whats going on then, the Car will start if i give it fuel & will only stay running for a few second(while i keep my foot on the gas) while it is running it is back firing and soundling crap then dies out PLEASE HELP

 

sounds like the timing is off

 

How Can i tell if it is off or not? i mean Prior to this issue, the car would start right up run untill it go hot (1-5 Min) then stall out....So i replaced the fuel pump,Filter,Cleaned the Injectors. How can i find out if it out of timing? and is that an easy Fix?

 

you would need a timing light, and youd have to verify TDC and the distributor rotar location.

is the check engine light on?

 

yeah the Check engine Light is on, i can't remember if it was always on tho? is it expensive to bring it to a shop and have them do it?
BTW THANKS FOR ANSWERING MY QUESTIONS

 

if the check engine light is on, then the codes its throwing will tell us more or less whats wrong.

do this and tell us what you get

 

its obd1 correct? or is there another way to check for codes? like the ingition on a jeep?

 

obd1 should be the same no matter what its in

 

obd2 came out in 1996 so im guessing odb1 but yeah i wanted to know if there is any other way of checking considering i don't own the odb1 scanner just the odb2 which dont match up

 

Buy a OBD1 scanner if you don't want to do it the free way like everyone else does

As Travis linked above in post # 8 (even has SIMPLE instructions)

Jumper the ALDL connector
and read the flashes to get the codes.

 

I think the plug wires are crossed. Double check the firing order.
