#16 of 17 Re: Plastic burning smell and hard to start [cuiosgeorge27] by atfdmike Jan 20, 2008 (8:28 am)
Replying to: cuiosgeorge27 (Jan 19, 2008 5:09 pm) It is hard at this point to give a specific answer...it does not sound good to smell burning anything in a car, but the smell could lead you to the problem area. You don't say, but can we assume the Trupr started OK after you got ready to go? Did you try to locate the smell? I think it is too early to assume the starting and smell are related, but it would help to know which engine you have SOHC or DOHC, and whether you have changed the fuel filter and air filter since you bought it. Information like this will help others pinpoint areas of concern. When you say you really had to gas it, do you mean that it started but would stall, or that you held the accelerator to the floor and or pumped it? Welcome to the forum, there are good people here who will offer their input once a good description is provided. Good luck.

Replying to: jfrozenh2o (Nov 28, 2007 9:13 pm) My 92 Trooper has the same problem. If it has been off for a few minutes, it fires right up and when it has been off overnight. When it has been off for a couple hours, it needs to be cranked for a long time before it fires.   Lately, on occassion, it has been chugging, stalling, blowing a lot of smoke and even backfiring. Then it runs perfecly except it seems to be running rich. These symptoms srarted a couple weeks after a complete exhaust system was installed from the manifolds in the fall.   Now it is colder and my trooper has flooded itself out twice now. I pulled the plugs to let it dry out and replaced the O2 sensor.   I've read your blog before (jfrozenh2o) and am leaning towards your idea of leaking fuel injectors, or some other fuel delivery issue. I've also read of others with hard starting issues and many trouble shooting possibilities, but no solutions or successful attempts to remedy these problems.   I love my trooper and just want it to run like it did a few months ago...and would like the gas mileage to go back to normal.   If the new O2 sensor helps, I'll post it. If you changed the injectors on yours, did the problem go away? My local dealer suggested a wiring harness at the front under the rad that typically turns green and cases problems. thanks, Kenny.
