So im starting to get overwhelmed at the issues I am dealing with on this car. Yes its old..yes its good...but we need to get some things straight. lol The car is not wanting to start. Where, when I got it last month, it would start at least a few times on the first crank. I've read several threads about cold starts and im still lost. What exactly do I need to examine? The first thing I got fixed was a fuel leak..at one of the fuel pumps. But I still smelled gas and with it not wanting to start next was the gas cap.. replaced that but still same issue.. I still smell gas sometimes though.. a spark plug was checked...not all.. figured if one was ok then the rest were and I know I should of checked but under the circumstances I was in ... one had to do..so why is it not wanting to start? it also idles rough.. and I need to know exactly what Im needing to buy in order for a break job? Anyones help will be GREATLY appreciated. Thanks u..

Check that you are getting spark and fuel on every cylinder. I'd replace the fuel filters and see if this helps at all.

Also, check out your cars specific forum. They have almost all the info you will need there.
