87 YJ hard to get started

After the awesome advice I got on my last post.....let's try it again. My YJ is running great once it gets started and idles for 15 minutes. It takes me about 10 minutes of cranking to get it started though. Any idea why it takes so much to get it going???

Have you checked -- before you crank it much -- to see if fuel is getting to the carb?

Fuel filter is improperly installed.

Normally that means your gas filter is in upside down if it is a 258 engine.

The gas filter has 2 outlets. The center outlet goes to the carb and the top outlet goes to the return line. If this return line isn't at the top, gas syphons back to the tank as it sits. This filter setup is to stop vapor lock.

If the filter is right, then I would suspect a pinhole leak in the line between the pump and the tank. They are suction lines so a leak might only just show as a stain on the line usually where it joints the rubber parts to the steel parts. It has to get really bad to drip, but it will still let air in when it sits causing a hard start.

This beast is a 4 cylinder....the fuel filter only has in and out.....it sits on the frame rail near the gas tank. It was replaced a month ago....I didn't notice and wet spots on the line

Too bad, the 6 is an easy fix.

What happens if you just turn the key to run for a minute to prime the pump and lines, then turn it off and back on to crank with the starter? If that works, you have a fuel pressure issue, either in the pump regulator or on the return line regulator up top.

If I had that trouble and it ran fine otherwise, I would likely just key it twice.

not sure if this will help but my 90 yj was doing the same damn thing and i found the problem to be with the choke not staying in the right position for starting.... or something like that, a buddy helped me with it and we adjusted it and ever since then one pump of the gas and turn the key and on my way.....
