Vapor lock 1990 jeep wagoneer - 1990 Jeep Wagoneer Limited

sounds like a hole in gas line or hose

TRY DISCONECTING THE DAY TIME RUNNING LIGHT MODULE AN LET IT SIT AND SEE IF THE BATTERY IS DRAINED AGAIN. IT IS ON TOP OF THE RIGHT FENDER WELL AND HAS TWO CONECTORS.

WARRNING IT MAY DISABLE YOUR HEAD LAMPS
DO NOT DRIVE WITH IT DISCONECTED.

REPLACE THE DRL MODULE IF THE BATTERY HOLDS THE CHARGE.

it maybe as simple as a burned out bulb, but buy a chilton or haynes service manual for your vehicle and it should explain more about the vehicle amd any light problems

I've had my 1990 Wagoneer since 2007, it was an old "City Park Vehicle" so it was kept in good condition until I bought it. I ran the poor thing practically into the ground and it still runs great!

You need to get under the front end of the truck - safely...
To the left or right of the fly wheel.. The fly wheel is a realy big round gear..
The starter will be mostly sylinder shape..
Should be easy to find..

You need to know haw to fush what ?
Breaks ?
Coolant ?
Trani ?
Oil ?
All ?

first check thermostat. when jeep is cold take out thermostat and see if you can move any parts . It might be frozen , if its good, then your fan is not providing enough cooling through the radiator to cool engine. if the fan is working properly, then your radiator fins are clogged and u need a through flushing.

does your jeep run rough? idle is real low? and when you are driving and push the gas hard it doesnt want to move? if so it is most likely the mass air flow sensor. i had to replace that 2 or 3 times on my 1999 jeep cherokee

Sending unit for the fuel gauge is not grounding correctly or is bad. Temp sensor needs to be replaced.

Try putting it in to 4 wheel drive then put it in reverse then put it back in drive.
