I have a 94 trooper. that I am having a hard time with. it will start on starting fluid. but after the starting fluid runs out it will still run if you pump the pedal. it runs really bad after the starting fluid runs out and it pops in the intake.I have changed the fuel pump and the map senser. I have 40lbs in the fuel rail.
#68 of 74 Battery dies overnight by willbee Aug 03, 2009 (9:35 am)
I have a 88 Trooper 11 2.6 L and had to put a new battery in her to start. Than to my surprise the next moring she would not start. Charged up the new battery and than she started up. Alternator is putting out when engine is running. Now I have to disconect battery cable at night so I can start up the next day. I must have a short somewhere in the vehicle causing this problem. Can anybody help me solve this electrical problem. Thanks
#69 of 74 Trooper has weird starting problem by jw_downtime Sep 17, 2009 (8:06 am)
Vehicle: 2001 Trooper Limited 4WD   130,000 miles   The Problem:   The first time the engine is run, it starts normally and runs smoothly for about 5~10 seconds. Then the RPM drops to a few hundred and the engine chokes, coughs, backfires through the air intake (not the exhaust). It often stalls and must be restarted. After about 5 minutes of the rough idling it will smooth out and run fine for the rest of the day. I will often get a P0300 error code (engine misfire) an occasional P0101 (MAF) error and P0440 (EVAP) code. These are never together (only 1 code stored), and do not always occur after the first starting (the P0300 being the exception) .   The engine trouble light will often “flash” after the above without any trouble code found, and the engine performance is sluggish. Usually the check engine light will go off and not return if I stop and restart the engine. After that the engine runs fine.   One additional symptom occurs (rarely) in that if I have been driving at highway speed for a lengthy time and stop – the engine stalls. But, it starts right up.   The engine burns oil (at the “normal”, for the Trooper engine - 1qt/1000 miles) and there is never any Blue smoke from the exhaust. It acts like fouling, except it start normally them the choking starts. I also thought about a clogged fuel filter or fuel pump, but that too would be a continuous problem.   Have you seen this behavior before? It does not seem to be getting worse, but with the cold weather it may become so. Replies to this message: mountaineers (Oct 29, 2009 4:39 pm)
#71 of 74 '90 Trooper won't start on incline by tiptopsu Oct 21, 2009 (3:18 pm)
I am the new owner of a 90 Trooper, carburated V6, manual trans. Getting used to the clutch, I let it die on an incline on several occasions. It refuses to start again on the incline.  Coasted back down to flat ground and it took several minutes before starting.  What would be causing this?? Thanks..

my 1998, 3.0 citation td lwb, when i start it up from cold, after 10-20 seconds the revs drop very low and smoke bellows out of the exhaust and this lasts for approx 10-15 seconds, then it revs up again and the smoke clears and its fine thereafter. Has anybody else had this problem ? many thanks

Replying to: jw_downtime (Sep 17, 2009 8:06 am) I had this type of problem and it ended up being a short in the engine wiring harness. It is common on this vehical because the run the harness across the top of the engine and sits directly on a hot surface.
#74 of 74 01 Trooper will not turn over by gwilsonh1973 Nov 04, 2009 (10:20 am)
Hi, I drove my Trooper to the store today and had to get it towed home. I turned the key and I got nothing. The dash lights would light up, but that is it. I already have a 3 day old, new battery, and have had the alternator checked. I thought that it might be the solenoid, but I tried jumping it and I only got sparks. So, I know that I am getting fire to the starter. I wanted to check the solenoid before I dropped the starter. Since it will not jump off the solenoid, that leads me to believe that the starter is locked up. Is there something else that I may be missing before I drop the starter? It is like putting the car in gear and trying to crank it. I get dash lights but no response, what so ever. If it is the starter, can I get around dropping the exhaust manifold? Thanks.
