i know theres a whole bunch of things but i wanted to see if anyone could maybe pinpoint whats wrong before i start replacing everything. but im having a problem the camaro seems to always start on the second time but it just doesnt want to start the first time. it turns over doesnt start then i let go turn again and it seems to start right up. any help would be greatly appreciated. its a 2.8 V6 if that means anything.

 

my old firebird used to do that when it would be cold out ended up being a cracked vacuum hose but it was a tbi v8 so not sure if thats your problem

 

Clean your fuel system and get a new fuel filter, and make sure your getting spark. You should be getting spark because it will eventually run. My guess would be the fuel system. Turn your key forward and just turn on all the electronics in the car and let the fuel injectors dump some fuel in the cylinders and then try it. It seems to me like it wants to turn over but it cant because your having a fuel delivery problem. But thats just my two cents....GOODLUCK!

 

Need to know the year (can't just assume here) and whether it's cold out where you are as these things act differently when it's cold.

Also, have you done a tune up recently?

 

Fuel injectors don't start pulsing until the ECM gets reference pulses from the ignition control module, so just turning the key on won't make the slightest bit of difference.

 

it an 89 and i dont think it relates to the cold. it may not of had a tune up recently. so i think it may need one. i just got the car recently from my friend a few months ago about 2-3. its been sitting since then. but the battery is good i had it tested and i didnt let it sit in the car while its been stored at my friends house

 

Well, let me say that this winter so far has been freakin cold and my engine takes FOREVER AND A DAY to start, unlike the last couple of years where it's been a couple of rotations of the crank and I'm off. The thing is that when cold, the fuel tends to condense into drops and fall into the cylinder instead of being a fine mist that's easily mixed with the air and burned. Which is why diesels have glow plugs, and some gas engines have to have coolant jacket or oil heaters.

However, if you're not sure if the parts (plugs, wires, filters, fluids) are good, then I'd start by replacing them and seeing where I end up.

 

My dealer, and my mechanic of 15 years told me that it will spray some fuel into the cylinders to get everything prepped to be fired.....

 

You know what it has to because my neighbor with a 91 RS 454 was having problems getting his to start and he kept doing that and flooded it, so it has to spray fuel!

 

Well, the 91 doesn't have a cold start injector, and I'm pretty sure that a 454 never had one. Besides, the only way the CSI works is to hold the key in the Start position (same circuit as the starter solenoid). If he cranked the engine long enough without good spark, it would flood, yes. However, if the 454 was carbureted, and there were a problem with the floats, the engine would most certainly flood out as fuel would pour right into the intake. Even mechanical fuel injectors don't operate until the next cylinder in the firing order has the intake valve open and it's sucking air into itself.

However, if neither of you believe me, hook a test light up to one or both of the ECM circuit grounds for the fuel injectors before you turn the key on some time. I guarantee that light will NOT come on until the distributor (or crankshaft position sensor, however the particular engine works) sees that the engine is rotating (been there and done this test). Or, you could just use a fuel pressure gauge with the system pressurized and the pump relay disconnected (to make sure there isn't a pressure drop of a couple PSI when the key is turned back on). Any pressure loss will equal a leaking injector.

FYI, most dealer guys are not ASE certified, and a good number of them are still in school. Most schools don't teach electronic engine controls until near the end of their classes. As for your mechanic, who am I to pass judgment?

 

Its not that i dont believe you im just confused lol, and his 454 was fuel injected
