1998 Jeep Cherokee 1998 jeep grand cherokee dies out

Don't spend anymore money on parts that may not need replaced. If the check engine light is on, scan it and post the code numbers here.

If there is a part to replace is your Automatic Shut Down relay. You may replace that. Then perform this daignostic.

NO START OR HARD START


Ensure battery is fully charged.

Check spark plugs.

Perform spark test.

Check for sufficient fuel and fuel contamination.

Check fuses.

Ensure ignition timing and fuel pressure are correct.

Check fuel injectors.

Check crank and cam sensors.

Ensure timing belt or chain has not jumped.

Ensure ignition coil resistance is correct.

Ensure rotor, distributor and plug wires are okay.

Check coolant temperature sensor and connector.

Check TP sensor and connector.

Check airflow sensor.

Check anti-theft system (if applicable).

Check for contaminated fuel.

Check for vacuum leaks.

Ensure fuel pressure is correct.

Check for gasoline in oil.

Check ignition and sensor wires for proper connection.

where would i find the automatic shutdown relay under the hood or inside the car

ASD relay is inside the Power Distribution Center (Fuse/Relay Box) under the hood.

i replaced the asd and so foar everything is running fine but the jeep cut out after i replaced the asd just a little but everthing is fine so far

All right. So far so good.

You did mention that you had the check engine light on. Please post the code NUMBER(S), not description.

yeah my check engine was on that problem has been fix it was my pick up coil and ingtion coil

I understand that. While most consumers will readily hand out their hard-earned cash, as a tech, I prefer to follow the proper diagnostic procedure for codes.

I took to a tech and he told me what to replace and worte the codes down for me that why i replace the pick up coil when i find the codes i will put them on here for u my jeep will start then die i wait a min then start it back up and it runs fine it seems like it does that after it sits for a while but i did replace the asd

Please do.

ok here the first code that pop up P0108 map circuit high output the second one is P0351 primary/secondary circuit malfauction

After reading the diagnostic, I can say that you have intermittent problems which for most of the time is caused by bad wiring. I would really suggest that you make sure all connections are tight at the coil and the MAP sensor, and also by the computer. Low fuel can also set off P0108 and bad CKP (crankshaft position) sensor may set off P0351.

where is the computer that and how do i change the crankshaft position senor and this code has pop up 3 times could it be a bad ignition coil senor and map senor

As you have replaced the coil and MAP sensor, I really think that it is the wiring to those parts. You have to make sure that the connectors are tight and there is no frayed wire. Connections at the part and also at the computer. PCM is at the rear right of engine compartment, near the AC receiver-drier.

CKP sensor is in the transmission bellhousing.

it was the connection to the computer that was loose and the part will be in on friday i hope this works and i will give you a tip friday

Phew... I am just glad we figured it out....Yea..
