Won't start turns over I see spark gets fuel . Any suggestions?
No engine size stated, (so i toss coin, 4.0L) 5miilion strong.
the 1988 is the gawd awful French RENIX fuel injection.
i owned 2 of these pigs. (sure it runs) but sux.
why?, no CEL lamps , no flash codes, no OBD1 , no OBD ! anything.
only the very old and rare factory and dealer tools can scan this pig.
lets do this better?
in vivid details.
NO start 101: (order matters too)
get the engine to run on test fuel first. this saves big time labor
down time, and wasted parts , guessed at)
doing a real tuneup , is not ever a waste.
a tuned up engine pays back in lower gas costs. big time.
fuel is expensive.

When it sounds like it wants to start but won't, it is almost always a fuel problem. When you first turn on the ignition key (radio off, in a quiet setting) do you hear a faint 'hum' from the rear of the car? If so, your fuel pump is probably alright, so the next check it to remove the small, light green plastic cap (it might be black, about the size of a tire valve cap) on the top of the engine-it is part of the fuel rail and has a small pin in the center of it. With a rag in your hand, hold it over the valve, and with the key on, use a small screw driver and push the pin in-the rag will keep you from getting sprayed, if all is alright, but if you get little or nothing, you have a problem with your fuel pump, filter, fuel regulator or you may have a plugged 'sock' at the bottom of the tank.

I had the same problem with mine. I have the same year Jeep. The Remote door lock also wouldn't work (Not on drivers door anyway!). Here's what I had found out from a co-worker with same vehicle. The wires in the door that run to the control panel on door for windows has been broken. You probably have several broken wires inside the "Rubber boot" you see when opening the door. You will have to take off the interior door panel, be careful to remove any wires and rod connectors when doing so. Then open the rubber seal. Find where the wires come in to door. Remove boot. Locate broken wires inside the boot section. You will then need to sodder in a 1'-2' wire to extend the broken wire(s). You may also decide to extend the unbroken wires now, just so you might not have to go through all of this again, later. I hope this helps out. I had found out it is a very common Jeep Grand Cherokee problem.

The Jeep DTC P1491 code is actually radiator fan control relay circuit.
Soft reset if the battery disconnect would have erased the code; the first thing I would replace for that code (fan relay).
Additionally, its possible thta your THEFT system is activated, check owners manual to disarm.
Hope this helps.

Plenty of causes. Plugs, valves. rings, numerous electronic/electrical faults. Diagnose vehicle and eliminate problems one by one.
