Well, first off... i am the proud owner of a stock 94 z28 with the LT1 350. it has around 172,000 miles on it, and i've only had it since june of '07. I love this car, however... i have recently encountered an issue. about a week or two ago i began having issues with getting it to start if i let it set for a few days... it would turn over but only to choke, puke, and die again after i let go of the key... when i drove it on a regular basis, it was fine... no problem right? well i was wrong... wednesday i was driving down the road at about 40 mph when it suddenly and for no apparent reason died... after about ten to fifteen minutes of cranking on it and doing the choke and puke thing again it finally started. when i went to give it a little gas i found out to my own dismay that it just bogged down and died... well after repeating the starting and dieing process a few times i could only step on the gas with only slight pressure anything more than just my big toe would kill it. A friend recommended to change the fuel filter and see if that was the problem... nope that wasnt it... the motor is getting fuel but only to spit and sputter off of when i let off the key any suggestions would be greatly appreciated... keep in mind i dont have much money right now so i cant just go out and throw a bunch of parts at it and pray it works... lol... anyone ever have this problem before? please help!

 

If it were me I would start by checking the coil first. I would then check the rest of ignition, and then work to fuel pressure and fuel system.

 

For starters, I would test the following:

Fuel pressure

Coil

Opti

Good luck.

 

Also i might add to the coil testing, that it can sometimes give a good reading when actually bad. Coils are weird. I would go to autozone and buy one, install it and then return it if necessary.

 

thanks ill have to look into it... a buddy of mine also suggested the fuel pressure regulator... is it common for something like that to just go out like that with little to no warning?

 

also, check for any leaks after the MAF in the intake elbow and in/around the intake

 

Mine acted like what you were explaining when the coil went out.

 

WHen all 6 of my coils (yes I said 6) on my 89 rs went out, it just died each time. Never to fire again.

 

My uncles high mileage lt1 had a problem like this. ended up being a plugged cat - if the coil/fuel pressure/etc turn out fine... check out that exhaust!

 

I had mine act funny on my LT1 where it would only start sometimes. It finally went out completely and never fired again. Sometimes letting it sit in between starts helped, but not always promised it would start again.

 

yeah thats one thing i already have that i can replace... the thing is i have to take the exhaust assembly over to a friend's house to have them cut and weld on the new cat that i already have... hes just hard to get a hold of... but thats a good suggestion... thanks to everyone for the input...

 

Doesnt sound like a cat, if it was the cat if would start after sitting for a little while then cut out later.

Like the guy above stated, check the fuel presure and opti and coil first then report back

 

Most likely one of these three.I am leaning toward the opti.Start eliminating the possibilities by troubleshooting.

 

Something like this happened to me along time ago...turned out to be the the fuel pump.....
have oyu been driving it on low fuel for a while?????

 

unfortunately, yes i have... i dont have much money to my name right now and just a few weeks ago i had started a new job... you know how it goes, borrowing a few bucks here and there just to have enough money to get to and from work... i won't get a paycheck untill the 14th my question however is this... when your fuel pump went out, did it still sound like normal when you were trying to start you car?
