well i bought a 1987 2.4L 4 cylinder hardbody, wouldnt crank, swapped out the fuel injectors, and it cranked right up

problem is it acts like a "rev limiter" at 2800-3000 rpm (dont have an rpm gauge so thats just a rough guess) other than that the truck runs good and sounds like theres nothing wrong with it... i pulled a code 43 off of the ECU which is injector circuit is open

now - when i pulled the new fuel injectors out of the old throttlebody i got them from i did knick the bottom of both of them w/ the hollow tube i was using w/ a rubber hammer as the repair manual suggested could this be the problem?

ive also seen fuel injector pump switch and fuel injector relay as parts for 87 HBs on Rockauto.com when i did a search for "Fuel Injector" and since the code sounds like its an electronic circuit it made me think they might need replaced?

im very weak minded on diagnosis and how most of the engine runs - im learning though and any help would be greatly appreciated

someone had told me to check all the wires running from the fuel injector to the ECU and make sure they are in good order - havent had a chance to pull the harness apart to do that yet though

any past history on it- like it sat for months before you bought it ,or?

You could try changing out the fuel filter.

it sat for months before i bought it - only because the guy who owned it before me was having the same problem, he replaced a ton of relays and the computer after they got wet, made sure the fuel pump worked, changed the fuel filter

i believe that is it - but ill have to ask him

not sure if i posted this in the right area now that i see a forum index related to engine... will be posting it over there and this one can be deleted or vise versa
