I been having issues with my 89 xj6 starting I had the shop check it out and he said the ignition coil was jumping spark so he changed it out and started up when I got it back it started up okay with a small misfire which it didn't have before I had it towed to the shop(it has had a misfire issues before tho it was fuel related) when I got it back I started it up next day and smelt super strong gas coming from the front and I could also smell it in cab no visable leaks I could see of and I called shop back told them what happen and they suggest it may be my injectors I had an issue with before I had boughten new injectors that didn't work so we reused the original ones and at the time they said the a couple injectors were not the best condition saying like it would flood. At first thought I thought it was ignition related but after smelling strong has ordor I think my injectors are clogged or flooding the engine he mentioned that my plugs were flooded I'm not sure on my next approach I spent all last year in and out of that same shop I don't really have money to keep doing the in and out of shop stuff and it's usually a no start crank issue I'm stumped and don't want to keep sending into a shop and not get it working reliably (it was starting and driving great until November late October I crashed and had to let it sit there I got busy and accidentally left it sitting for 2- 3 weeks I was starting it everyday until I got busy and then my issue started there again. I ended up fixing my tie rod which it what broke in collision

 

Common problem with running rich is the water temperature sender unit saying engine cold and activating the cold start injector.
I have had this problem on my series 3
