Where is the temperature sending unit on a 1988 Toyota pickup?
If it's not located on the thermostat housing, where the top radiator hose attaches to the motor, then it's under the intake air chamber in the head.
On my 88 Toyota 2WD pickup, some fuses are under the hood on the RH side behind the battery. Others, and the flasher relay, are inside the cab above the floor behind the kick panel on the LH side. Take out 2 screws that hold the kick panel on. There is a lid over the fuses with some of them labeled.
The first Toyota 4Runner was introduced in 1984 as the 1984 1/2 models. It was nearly identical to the Toyota Pickup mechanically and was primarily different from the cab back. I found recalls for every year from 1988 to 2003, but I did not find any after that. Some of those recalls were minor issues and others more significant.
Does a 1988 Toyota pickup truck 2.2 22re4wd have a mechanical or electrical fuel pump and where is it located?
Can the oil sending unit cause the fuel pump to not get fuel to the throttle body of a 1988 Chevy S-10 pickup?
YOUR ANSWER WILL MOST LIKELY BE A ''NO'' THE ''OIL'' SENDING UNIT DOES NOT HAVE ANYTHING TO DO WITH THE FUEL. (JUST OIL) THE JOB OF THE SENDING UNIT IS TO LET THE DRIVER KNOW THE HOW THE LUBRICATING SYSTEM IS WORKING.EX. LOW OIL PRESSURE ,OIL LEVEL IS LOW, HIGH OIL PRESSURE ETC THE SENDING UNIT WILL SENSE THE "CHANGE" IN THE LUBRICATING SYSTEM AND TURNS ON THE OIL LIGHT IN THE DASH BOARD.
