SOURCE: replacing fuel injector on jeep 2.5

Disconnect your Battery.
Remove your air intake and filter housing all the way to the throttle body. Then use a shop rag and release te pressure in the fuel system by the valve on the fuel rail. use the rag to absorb the fuel as it sprays out the fuel rail.
then you unsrew the 2 bolts holing the rail in place.
Then you pry the rail away from the manifold with a flat head.
being careful not to loose any of your injector seals.
when done clean both your injector seats and the rail seats.
use some assembly lube or shop grease to lubricate all of your injector seals upper and lower seals.
remount all parts as you dismounted.
reconnect your battery cylce the ignition key 4-5 times before starting the egine, and check for leaks. if there is no leak then go ahed and start your engine.

SOURCE: engine compartment wiring diagram for a 88 cj7

The last Cj-7 was built in 1986. And they didn't come factory with a V-8 so you have a conversion of some type. Most factory wiring diagrams aren't going to help much. Sorry

I have a 1999 Jeep Grand Cherokee limited,V8 Quadra-trac which dies on the road; dash gauges drop; "no key" lite displays on dash. Restarts after cools. Two codes P 0443 and 0308 are showing? help

code p 0443 refers to evaporative emission (EVAP) canister purge valve ---circuit malfunction====causes ---wiring--- EVAP canister purge valve ---ECM
code p0308 refers to cylinder 8 ---misfire detected ====causes ---engine mechanical fault ---wiring----ignition/ fuel system--- injector---ECT/MAF sensor---ECM
I am thinking here that it restarts , not after cooling , but after the vacuum in the fuel tank has lessened and allowed fuel to be pumped to the injectors and the fuel pressure is re-established
if that is the case then a weak injector or partially blocked injector will misfire under those conditions
I would fix the purge valve so that the tank vents properly and the rest may go away

Replacing Fuel Injectors

there is a 100s of pages for electrics in the FSM>
or at
but you must know what engine you have first.

what kind of diagram. there are many, mech. electrical, , assemble, etc.
the injectors have a common 12vdc power feed.
then each injector is fired with a single wire from PCM to each injector
this is done using a power transistor in the PCM.
it acts as a switch grounding the injector for say 5/1000 of a second
and it squirts.

My 96 GC 5.2L V8 started acting up a few weeks ago by taking several turns of the key to start. Now the only way it will start is if I add starter fluid to the throttle body and once it starts it runs...

This sounds like a weak fuel pump, put a preasure gauge on the fuel rail and check the preasure with the engine off turn on the key and preasure should be 47psi to 51 psi.lower than 47 replace the pump, a few pounds make a big diffrence when trying to start,

95 Jeep G.C. Laredo won't start

Make sure you have fully charged battery so that the engine will turn fast when attempting to start. Insure you have power to the injectors while attempting to start. If there is power there then check that you have enough fuel pressure from the pump usually 60psi or more. You can call the parts store and they can look up the pumps operating pressure. If there wasn't power to the injectors it want run. Sometimes the power source for the injectors is ran through the oil pressure switch. This switch could be sticking. Check your wiring diagram for your power source. If your engine did not turn over at all your problem would be with the starting circuit. Starter or it's power connection. I hope this helps God Bless
