Ok, the injectors I ordered are on the way.
In the meantime, even though I probably don't need a computer, I did fancy a browse around the local pick a part which had a 90 B250 and a 92 B350 in stock. I got a computer and a fuse box, and also grabbed all 4 fuel injectors from those 2 vans - pictured. The 92 had odd injectors, the other 3 all look the same.
My existing ones are like the blue topped one, smaller and stamped "mini injector" but neither of the two types seem to work in my van. From the moment the key goes to position 2 they just spray fuel big time, gushing.
So does anyone know if these injectors are very specific types and not very interchangeable?
I put my old one back, and yet again, because I had messed with it, the engine ran fine. But this time, it ran fine for about a minute and then went back to its old ways.
So, fine, I'll wait for my new ones to arrive on Monday. Except now I'm worried they won't be the right thing and will gush fuel like the two used ones I tried.
What I ordered is a Standard Motor Products TJ22. According to rock auto that is the right thing for a 1990 (the one at pickapart) as well as a 1988 (mine) - if fitted with 5.2l (which mine is)
it is possible that the engine on the '90 B250 was a 5.9l. It did look the same as mine, but I wasn't looking that hard. Do they look more or less the same?
If it was, then the injector is different, according to Rockauto a 1990 5.9l takes a Standard Motor Products TJ37
The 1992 B350 (the other van I got injectors from at pickapart) takes a TJ37 in the 5.9L. The 5.2l takes a different style (one in each cylinder/fuel rail) so it must have been a 5.9L
So, my questions, to summarize, are!
-do the 5.9 and the 5.2 look more or less the same to the untrained eye (me)
-will the different fuel injectors between the 5.2 and 5.9 be incompatible and explain the lack of success I had with the used iones I got and reassure me the ones I ordered are probably right?
