Check the power fuse to the computer. If the computer does not get power the engine light will not work. If the computer does not work it cannot ground the relay to the fuel pump.

Take your fob to a parts house and they have a fob tester to make sure it is not the fob.

You may have a bad coolant temp sensor but the only way to prove it is took hook into scanner that can read data, also check the fuel pressure. Note if the ect is bad it will be reading -45 no matter what the temp is it will get better as the lazy sensor catches up. I hope this helps, Take care

does this happen when using the remote to lock/unlock vehicle ? if so thats perfectly normal as long as it's only for about 15 seconds or so

Go online and download an owners manual for the Jeep. It will give you the location of the fuse associated with your dash lights. Or you could start pulling fuses and looking for the one that is blown.

Are these your wire colors for headlamps? In the diagram, the top wires are voltage, the bottom wire is ground, check both. There is no fuse for headlamps. There is internal circuit breaker in headlamp switch. The exterior lamps not including headlamps are fuse protected.
Maybe a problem with bulb or wiring circuit. The voltage for hi beams on both sides, come from the same place. Lo beams, the samething.

Sounds like an intermittent miss. Possible worn plug, bad wire, or an injector that is shorting out. Check to see if any codes are set. This will help you narrow the problem to a certain cylinder.

IAC was a good guess...

ALSO sounds more like a throttle position sensor...

(TPS is my GUESS... but it is your MONEY and
this EASTER-EGG hunting style trouble shooting
can typically cause MORE TROUBLES than fixing).

(( but still preferred over taking it to a "DEALER" )).

My BEST suggestion... Get your codes read...
and AVOID the pitfall of needlessly replacing
those rather expensive OXYGEN SENSORS

Doesn't cost you a thing to bring those trouble
(DTC) codes back here and give us another
chance... (I'm just saying).

Look at the costs at ROCKAUTO... (great catalog)

When that code shows up, it normally means that the O2 sensor is bad, or there is a bad connection or burnt wire. All of which are corrected with replacement of the O2 sensor.
