HELP!!!My 91 camaro RS with an auto trans and 305 TBI just crapped out on me today.It was running perfectly fine yesterday and this afternoon,when i was about to go to school,it just cranks over and wont start.Gave me no signs of it going out before when i was driving it.ALL AND ANY INFO WILL HELP...I dont think im getting spark or fuel...BTW what is an OPTI?PLEASE HELP I HAVE SCHOOL TOMORROW

 

Find out if your not getting spark or fuel.

for spark a quick was you can check, pull a plug wire of a spark plug and stick a scewdriver in the wire where the plug was, and hold the metal part of the screwdriver close but not touching something grounded (metal). start the car and see if a spark jumps from the screwdriver. (or get your budy to hold the end of the wire for a second and sneek around and start the car)

for fuel you need a fuel test gauge, or if its TBI take the air fillter and look and see if fuel is spraying out the bottom of the injector

 

Tried both methods, its not getting any fuel or spark...HELP!

 

check all your fuses.

Don't foget about the one by your gas tank (don't remimber exactly where, think it's in front of it above the rear end

 

would that still cause it to have no spark?

 

if two fuses are blow, like the ecm or something like that

do you have spark from the coil?

 

Nope, no spark, and when my brother cranks it, there is no fuel being dumped down the shoots. Radio and other electrical seem to work just fine. It was running fine the other day, and when I was about to leave for school, all it would do is crank over. It wouldn't catch... I checked the fuse near the coolant- in front of the engine, I also checked the injector fuses and ECM fuse under the dash- ALL looked okay. I'm stumped

 

There are 2 fuses for the ECM? I only saw one under the dash.

 

there's only one.

Stupid question but's its got gas in the tank right

just shooting in the dark, do you still have your old chip. you could try putting that back in. I'm just tring to think of what would take out you spark and fuel at the same time.

 

have u checked the fuse that is on ur pass side in the motor bay right near ur battery that is for ur fuel pump but that still doesnt explain ur spark problem check ur cap and rotor if the rotor broke u wont have spark my buddies car had that problem

 

hehehehe yeah,theres gas in the tank.It was running perfectly fine yesterday.Then overnight she died.I'll be getting my old chip tomorrow from the previous owner.

 

checked it out and it comes out clean

 

well i think its the ECU.I'll see if i can pull it out tomorrow and get a new one from autozone or the dealer

 

Yo Night Rida, You ever find out what was gin on with this?

 

Possible could be pick up inside distutor that cause no spark and no fuel. 1. turn ignition on and check if check engine light is on.. if its on computer could be good and doesnt need to be changed. Number 2 i would get a test light and i would remove the injector off and stick a pin and make a lube on the injector with test light and have someone crank the engine ansd see if theres a power coming into the injector. If theres no power possible computer. If there is a power into the injector no spark and no fuel change the pickup inside the distributor. Note: dont forget to check the fuses by a test light!
