Question about 1999 Jeep Wrangler

1 Answer

My '99 Wrangler Sport used to start on the 1st couple cranks. Now it takes about 20 cranks or i can turn the key off and on a few timeswithout cranking the engine and then it will start. This is only when cold. I believe it is taking additional time for the pressure to build in the fuel system, but where is the pressure going when the vehicle sits several hours? If there is leak, should I not see or smell gas somewhere. Any suggestions to fix this.

You are correct. the fuel system is loosing preasure while sitting and then it takes time for it to build back up, you will not smell the fuel because its the preasure regulator valve in the fuel pump, so it just drain back into the tank,this is common on chry,and jeeps. the preasure regulator in the pump is bad, you will need to replace the pump asm. this will solve your starting problem, hope this is helpful.

You can mount a fuel pressure guage to the engine fuel rail at its bicycle valve bleeder, with tof see if it has pressure when you first turn on the key to start. You may be able to hear the fuel pump running by listening at the fuel tank fill cap that you would remove for that moment. By turning on ignition to start, not run, you are energizing the fuel pump to bring up pressure that should happen in several seconds. So, check if it gets to normal fuel starting pressure, maybe 45 to 60 psi. Then turn key all the way to run, to get car engine running and watch the fuel pressure to see if it stays pretty constant at that 45 to 60 psi. Turn engine off, and watch how long it takes for fuel pressure to drop, and it should not happen fast but instead over 15 minutes or more. That might indicate your fuel regulator valve isn;t working right.
Is it possible your starting system is the culprit, say some battery cable loose that may make starting hard or eventually quit until you tighten these cable ends at battery and starter.

99 Jeep Cherokee Sport, 4.0L -won't start


you need to have it connected to an OBD2 machine and watch if you are missing the cam sensor showing RPMs
or if your missing crank sensors RPMs,
it could be a wiring problem or computer if your seeing the RPMs from both sensors,and the last thing i would check is hooking up a fuel gauge to the reed valve and watch what fuel pressure you have while cranking,if the cam sensor is the culprit it will turn the fuel off after the cranking.

quite possibly it may be taking a little while to build fuel pressure. next time try cycling the key on and off 3 or 4 times with out cranking the vehicle to allow the pump to build pressure the try to star it up if it starts right up then your problem is it's just taking time to build pressure

99 Engine is OBD-II.

It must match with the same production line ECU.


You may luck out by getting the chip set for the ECU.


Did you purchase the 99 engine,ECU and the wiring set OFF THE SAME Jeep.

The key is to have a matching ECU firmware to drive the injectors and read ALL sensor.

This can be your major miss-match.
