94 ZJ cranks but won't stay running

I'm looking to buy a 94 ZJ I found for 1200. The add says it will start but won't stay running. Would this be a quick fix at a good price or is it something serious and expensive to fix. Sorry I don't have more details other than its the 5.2 motor.

Price seems a little high for a semi running vehicle. Most of the the time something like that is an easy fix. But can be expensive. One test you can do is start it with the gas pedal pressed on a little. If it starts and continues to run with the gas pedal depressed its the iac. Easy fix/cheap. Then to drive home youll have to drive two footed at stops.

Hard to say. Don't want to say yes and it be a pos. Depending on the tranny, sounds like governor selenoid has gone out. Never done one on these but I know you got to dive into the tranny a little. Not a removal but take pan off and a few more steps. Or its a torque converter not going into lock up. $150 plus removal of tranny. And the Speedo not working is the the rear sensor in the tranny/transfer case(can't remember what its actual name is, output shaft speed sensor????????). Is easy fix, but I think it about $50 for the sensor.

But for $800 you have $400 more to play with to get it right. My 2 cents

speed sensor needs to work for the overdrive to engage, same problem with related symptoms.

the first one could be an alarm related issue. my 95 did the exact same thing, disabled the alarm and all is well.

inside the drivers door, there is a purple wire with a white stripe. ground it out and it will completely disable the alarm system.
