I am looking to puchase a one-owner 87 trooper 2.3L for my daughter. Per the current owner, the vehicle has been left sitting for the last 2 or 3 years, being driven only very ocassionally. It will start if she pours gas down the carb, but will only keep running at very high RPM's (>3000), and otherwise stalls out. Because I haven't bought the car yet, I haven't had a chance to do the usual "first" things like changing the fuel filter or checking the fuel pump/relay, but I wonder if anyone else has seen this problem or has suggestions as to what might be causing it.

There is no fuel shut off on that vehicle ! What is the problem ? No fuel ? Check fuel pump relay for battery voltage an control from the ECM / PCM -The engine computer energizes the relay coil by supplying a ground, there by closing the contacts allowing current to flow to the fuel pump ! On the bottom of the relay or the side is diagram of the relay pins 30, 87 are the load side, fuel pump an 85,86 are the control side , battery voltage an ground from PCM
Yes there is a fuel reset. You will have to check out your manual for its location. Most of the times they are in one of two places. Behind the kick panel on the passengers side or in the back of the vehicle behind a snap on panel.
The diodes are there to prevent a current back-feed, yes they need to be there. The knocking may be a fuel seperation problem [ ethanol seperation ] from setting. Useing a fuel stabilizer when storring a vehicle for long period of time will prevent it.
Hope this helps you.
Government mandates all vehicles can run on 87 octane. For that vehicle it would be just fine. I de rec. To do a tank of 87 check milge you are getting. The run a tank of 89 check milges and calculate the differnce milge and cost. I have found with some vehicle the extra 1$ or 2$ you may spend on 89 will get you 2 -3 mile more per gallon.
They usually mount that stuff on the frame rail- you have to lay down under the car and look along the rail - trace the fuel lines coming from the fuel tank, you'll find it. On my 93 Rodeo its right below the driver door mounted on the inside frame rail.
Power drive delays the shift points for upshift of the automatic transmission. It will degrade fuel economy, but you'll get more peppy performance.
Winter drive will only engage if the vehicle speed is below a certain threshold (I think 23 miles per hour) - and only if the vehicle is in Reverse, Neutral, or Drive. It causes the automatic transmission to start off in 3rd gear (rather than 1st gear). The purpose is to provide power, but not torque to the tires. In winter driving, torque increases the probablility of the tires spinning. The vehicle will seem to be VERY sluggish when winter driving is engaged - which is completely normal behaviour. It will automatically disengage when vehicle speed increases above the threshold.
