I live on a boat access only island, so desperate. This jeep has over 230,000 km on it. Runs well, but this year started this thing where it won’t start first time crank, but always starts second or third go. Any ideas? Bought new battery last year, so doesn’t seem to be that kind of issue. Thanks in advance for any help you might have. Hate to have to barge it off to get it looked at.

The next time you go to start the engine, turn the ignition switch on so the dash lights come on for two seconds, and then turn the ignition switch off.

Repeat this a half dozen times and then try starting the engine.

If the engine starts right up, it points to a defective anti drain-back valve on the fuel pump assembly.

Sounds like a fuel pressure problem

I agree with Tester’s comments. My wife’s 1997 CL has been doing it for the last two years now. It takes two attempt to start the engine. I have no desire to have it fixed since the check valve is part of the fuel pump assembly inside the gas tank and too expensive to fix. The check valve prevents fuel from being siphoned back into the fuel tank and keeps fuel pressure in the fuel rail after you shut off the engine

I consider this a minor inconvenience and will not do damage to the engine. If you do not like it, you can get around it by turning the switch on and off again and then all the way to start to start the engine.
