No start-up til 3rd try. Everytime!
I have an unusual problem that I'd like some input on. I have a '98 XJ with 125,000 miles and when I let it set for few minutes or longer and go to start it up it turns over without firing. The only way I can get it to start is by turning it over shortly THREE TIMES and finally on the third time it hits and starts up just like it should. NO hesitation. It started over a year ago and has gotten worse over time. Meaning It use to be the second try it would start up just fine. Now it takes three tries. Here is a list of things I've done to try and fix it.
Fuel pump, fuel filter, fuel pressure regulator, coil, wires, cap and rotor, coolant temp sensor, throttle body clean (including IAC), spark plugs.
Any suggestions or wild guesses will be appreciated. Thanx.

you could put a check vavle in your fuel line. maybe after you kill the engine all your fuel in the lines dump back into your tank, causing you to have to turn the key two or three times to get the fuel back to the spark plugs. JMO

i agree .... sometimes if you cycle the key without actually starting it you will build up fuel pressure... it could be a weak pump ... i have a similar problem and as long as i turn the key and wait for the pump to finish priming itself before actually cranking the jeep it starts no problem ... also i would check your idle air control valve or (IAC VALVE) as some people call it ... if your valve is getting a little sticky it wont read what position the throttle is in an it will screw up the computer an it wont give the proper amount of fuel ... the iac valve is cheap too

Same
I have the same problem. Did you come up with a solution??? It is an embarrassing problem. I just bought the Jeep last weekend and it's a problem I'd love to fix.

If it runs decent/well after start up, The Cam sensor is probably alright.

All XJs will start quicker (with fewer revolutions) if you allow the pump to pressurize the system first. It cuts cranking on mine in half, at least.
If this doesn't change things, you'll know where to look next.

First, just try turning the key on and waiting three seconds before turning the key to crank position.
