Camaro 92 RS Starting problems on hot engine

[robertjamesmoore]

Hello i have a 92 Camaro RS TBI V8 305, it has some wierd problems when ever the car is cold it starts normaly after use when the engine is hot it will have a problems starting back again i have to pump the gas pedal for it to start, once it starts you can hear the TBI hiss a large amount of air, so then driving the car the SES light will appear and wont turn it self off. I had recently changed for this same exact situation the IAC, also replace sparks with new cables.
Can any one point me in the correct direction to get this FIXED thanks !

What is your fuel pressure at? Could be pump, injectors, or fuel filter I just had similar issues if you want to check my thread.

Not that this could be your problem, but it proved helpful to me...I found this on some thread

"Do Your Fuel Injectors Need Replacing?
Failed fuel injectors can be a cause for a great many problems with your cars overall performance. Whether your car has an electronic fuel injection system (E.F.I.) or a constant injection system (C.I.S.) the problems experienced from both are very similar. Here are a list of some of the symptoms you may be having caused by poor fuel distribution by faulty fuel injectors.

(1 Hard Starting
(2 Poor fuel economy
(3 Rough Idle
(4 Car runs fine when cold and terrible when warm
(5 Car will start just fine when cold and not when warm
(6 Getting a fuel smell inside the car
(7 Loss of power in acceleration
(8 Fuel leaking from injector seals or injector

Injectors are just as easy to replace as your spark plugs. "


Definitely check your fuel pressure you should have around 42 psi at the rail bleeder.
