1990 LE250 12v engine problems
Alright guys I've had my truck for about a year now, with no major problems other than the ones I knew It had when purchasing it(electrical problems). Yesterday night when leaving work it seemed the idle was incredibley low. Almost to the point of stalling but mostly just some shaking. And when you would step on the accelerator it would shake/bog down at first then act normal until you come to a stop or low enough rpm then it would continue. It's also been throwing ALOT of white smoke out of the exhaust. And it also smells different I have noticed. Now when I went to start it this morning it would not start at all to the point of my battery getting pretty low from trying. This has happened Monday and Tuesday of this week aswell but the truck eventually started. When I got home from school I tried again but to no avail, so I cracked my injectors and cranked it to see if maybe there was air in my system but again it still wouldn't run(although i may not have done it correctly). Could it be a bad pump? Bad injectors? I'm unsure as this is my first diesel vehicle. Any help would be greatly appreciated, thank you.

Most likely (and cheapest/easiest) is a clogged fuel filter.

not really sure to be honest. I bought it off the original owner and he kept meticulous records so I'll have to look through them and see.

They'll look it up. I don't have the number handy. I prefer Fleetguard, but it's not that big a deal. Get whatever they have.

Remove the water sensor/drain on the bottom of your old one and install in on the new one. My truck had long ago had those wires cut off but I still used it as a plug. Just put as much diesel in it as you can before installing. I didn't have to do mine often enough to remember all the issues, but it twice cured my symptoms of no power with white smoke, and is still way cheaper and easier than any other possibility. It's something that should get changed anyway if you don't know how long ago it's been.

will do, I ended up calling auto zone and getting a filter through them, half the price and a bunch of people told me they've been stranded because of the napa filters.

The filter was in all reality likely last changed in '05.
Change it as that was almost 13 years ago.
