Starts but wont stay running

I have a 91 Camaro RS that starts but wont stay running for longer than 3 minutes. I had a mechanic come look at it and he sprayed something into the filter and it stay running. He then told me that it was fuel related but it was not the fuel pump. Does anyone have a clue what it could be?

In reply: if its not the maf there are 2 relays in the relay box i belive its underhood, 1 primes the fuelline to 32psi the second kicks in after it starts, and keeps it running and varies the psi. if the primer relay isnt kicking in then it wont start due to no fuel

I had that same problem with my 91 RS a year ago. My fuel injectors went bad. I had them replaced and the car runs great now. The total for parts and labor was around $1,000.

I would take an inexpensive pressure gauge and check the fuel pressure it should read about 40psi.when turning key over to on position.if it don't then you need a fuel pump.

91 camaro rs 3.1 v6 will not start has code 12 and code 54


Well code 12 means you are in the test mode of the computer, so skip that one.
Code 54 is telling you the fuel pump circuit voltage is low, which could be the pump relay.

I do not get a start up pluse on 91 Camaro RS 305


I assume you are not getting fuel spray from the injectors ?
If you are getting voltage to the injectors you should be able to ground and get a spray. If no spray, they may be stopped up from sitting.

You need to run move diagnostics. You are getting fuel up to the injectors but are the injectors spraying.
How do you know that your pump is fine? It might be running but is it building up the right amount of pressure? What is it at? If it is below 33psi then you may need a new pump or possibly a fuel pressure regulator.
If it passes then you will need to test the injectors. You can go to the part store and buy a repair manual and a special key that allows you to retrieve the codes that are stored. If you write back with the code numbers I can give you the definitions. Good luck.
