I’ve had a lot of problems w this car since I bought it in October tryin to get it to run right.it’s a 84 olds 98 w a ccc 307. I’ve made a few other posts on here and the responses have been very helpful, but now this thing won’t run at all. I changed the fuel pump and I changed the plugs (with the gap set at 45.) and it ran once after I changed the plugs and since then it cranks but won’t fire. I changed the fuel pump again thinking I might have got a bad one and it cranks but won’t fire it has spark but I changed the ignition coil, cap, and rotor and it still won’t fire. What else could be keeping it from running? I sprayed starting fluid down the carb and it kinda sputter but won’t fire

 

How about you stop replacing parts and start troubleshooting. Do you have spark at the plugs when you crank it? Does fuel shoot out of the accelerator pump jets when you pump the throttle while looking down the carb? Those two things will tell you if the problem is fuel or ignition, for starters - without spending any money on parts.

 

it has spark at the plug I put my spark tester on there, I haven’t had any one else around to push the pedal while I look down the carb. I did pop the line loose and crank the motor into a container and it is getting gas up to the carb

 

So stop buying ignition parts.

Simply look down the carb while moving the throttle arm on the carb with your hand.

 

I did that and I didn’t see any gas come outta there

 

How many miles on it? Distributor by chance loose, can you rotate it? Any backfiring through the carb?

 

So now figure out why - blocked fuel filter? Gummed up carb? Cracked rubber hose from the fuel tank to the hard line (so the pump is sucking air instead of fuel)?
And while replacing old parts is fine, I suggest waiting until you find the original problem, since the act of replacing parts can introduce whole new failure modes and compound the problem.

 

when I first got it and it ran, it would get sluggish up hill or at speeds above 45 so I checked the timing and it was good
distributor hasn’t moved

 

i changed the filter when I did the pump the first time and that was before it quit running all together
I dropped the gas tank and looked at the sock filter and changed the rubber lines between the tank and the hard lines
It’s getting gas from the pump to the carb so could that mean my carb is bad?

 

Next obstacle in the fuel line is the filter in the fuel inlet nut at the carb, even if you changed it that is more suspect than a carb problem.

How many miles on it?

 

It’s got about 110,000 miles

 

alright that’s what I’m gonna do next

 

Do you have the check valve style of fuel filter in the carb? When you do pull the fuel filter, check to see if it has a check valve one end of it. That is the little check valve thingie that supposedly is there for 307s as an anti-drainback valve. It may be sticking causing some issues. Perhaps. IIRC, it's the type of fuel filter called out for all 307 applications.

ACDelco GF471 or equivalent is the check valve filter.

If you wish, find an older AC Delco GF441 or Wix 33048 filter. It fits the same, but should not have the check valve.

Or, it could be you do need the anti drainback feature which could cause what you may be experiencing. At least until the pump fills the bowl again.

Just an idea to check while you're in there.

 

Unless you are getting too much gas into the motor, starting fluid, carb cleaner or a shot of gas should run the motor momentarily. Being a computer advance distributor means as long as the pick up coil is good and unless the distributor moved a lot, spark timing should be right. It sounds carb related especially after going through the whole fuel system. Everyday Performance rebuilds the CCC carbs, don't trust the mass produced reman carbs.

thats something to consider
I didn’t realize there was a check valve in the filter. I used a Fram filter I don’t remember the part number tho

 

I replaced the filter w one that doesn’t have the check valve and she fired up
