Try replacing crankshaft sensor. Cost is about 45 dollars and not hard to get to. Facing the engine from the front of the car it is located on the right side half way down the block. One small bolt and an electrical connection to remove. Be sure and keep white cover on sensor clean when installing new one. Available at local parts dealers .

I have a 1998 Jeep cherokee sport. Was driving today and it died. Now there is no spark and no power to fuel pump. Changed fuel pump today and it won't run. Recently replaced oxygen sensors too


U need to check the crankshaft position sensor. The fuel pump will only have power for 2 seconds I till it sees a crank signal. It' controls the asd relay which turns on your spark and fuel

I cant find the obd plug in on my 94 jeep grand cherokee laredo and my jeep will turn over but is hard to start what would cause this?


It does not have an obd11 connector, it's too old. The extended crank time could be a couple of things though. I've seen problems with fuel pumps, fuel pump relays and crankshaft sensors. How many miles on it? Has the fuel pump or filter been changed before?

1990 Cherokee starts but cranks for awhile


Try this: turn key on for 5 seconds,but dont start. turn it off and turn it on again for 5 seconds then try to start it. If it starts up better, you need to test the fuel pressure.
hook up a test gauge to the test port on the fuel rail, try to start and watch fuel pressure, after it builds.to its max turn engine off, it should then hold pressure for a few or more minutes. if it doesnt there are three things that can let it bleed down.

There is a check valve built into the fuel pump that could be stuck open,
An injector could be leaking,
Or the pressure regulator could be leaking.
If it still has problem check your spark plugs to see if they are worn out with too much gap.

does your jeep run rough? idle is real low? and when you are driving and push the gas hard it doesnt want to move? if so it is most likely the mass air flow sensor. i had to replace that 2 or 3 times on my 1999 jeep cherokee

90 jeep starting problem


Check the crank position sensor. I had the same problem in a 1989 cherokee 4.0, and the solution was simply to acomodate the sensor wiring. No replace was necesary

1998 Jeep Cherokee - hard to start


My 98 Cherokee was the exact same. I used to have to turn the key back and forth 3 times and then it would start. Otherwise it would just crank and crank for a while and then start. Pretty embarrassing! Took it to the dealer and they said that my fuel pump was losing pressure. I changed the fuel pump and I don't have to prime the pump anymore.

I have a 1991 jeep cherokee that recently started having random problems when accelerating, it's idle starts fluxuating and it spits and sputters and bucks, before it finally wants to go. Also it randomly...


First, check ignition system...cap, rotor, wires & coil. You may have some arcing going on there. If plugs are not recent, take a look at them as well...even if they are good, they can often tell you which cylinders are having a problem (wet with fuel, heavy deposits or just "different" from the rest) You may not hear the fuel pump come on all the time if the pressure in the line is not bleeding down. I would take a look at the relay first (power in & out). If fuel filter is more than 1yr old change that. (routine maintenance regardless of problems) Pressure test system if in doubt. Make sure idle air system is clean and do a quick test on crank sensor (a known problem area). likely something here will get you going.
