Hi, I recently acquired a 1990 Toyota pick up that has the 2.4 liter 4 cylinder engine in it, under 200 000 Km on the odo

I am having three issues two are related (I think)

1. The truck takes two tries to a start every time (cranks good Batt is not an issue)

2. The truck diesels after I shut it off almost all the time. ( have not checked plugs yet )

3. The oil press sending unit is U/S nothing on the gauge stuck at Low end.
(apparently this has been changed before according to the previous owner)
I have ordered an new one but would like some help from the you guys as to locating it on the engine.

1 and 2 sound like a timing issue.

The oil pressure sender is on the passenger side of the block near the oil filter.

Update: New Plugs seem to help, still diesels a bit on shut down. It the timing hard to adjust on the 2.4 liter?

The oil Press sender was an easy fix wire connection had come off.

Any help would be appreciated. Thanks

Go to a parts store and buy a Haynes or Chilton manual. While there, rent a timing light. Timing is adjusted by rotating the distributor.
