What the hell is wrong with this thing?????
I got a 89 2wd and it only runs on 4 cyl, 3 and 4 are ice cold when you tought the manifold. Ive had the injectors tested, moved them to different cylinders, took the lines off 3 and 4, blew them out with the air hose, and cleaned the delivery valves out. My dad thinks its a burnt valve, and ive heard it could be something in the head of the pump, because before i cleaned the lines it would just puke some fuel out of 3 and 4 when you cracked the injectors loose, now after i blew the lines out they're fine.
So does ANYONE have an idea of what it could be???? :argh: |
Not sure how you get an injector line clogged, that's a new one on me. I have to agree w/dad, probably update sig - To come: valve job...
|
Provided that you get fuel out of all six injectors when they're cracked open and you're cranking...
Then I'd say it's time for a compression or leak-down test. |

what size adapter do i need? and where do i get it? And whats a leak down test? :w2:

a leak down test is a set of guages that you put air into the cyl( piston up both valves closed ) it will tell you if the valves are bad or rings or head gasket it shows a percentage of the air leaking you will hear it in the intake or exhaust if its valves or blowb y tube if its rings and make bubbles in the coolant if head gasket it gives you an idea of where to start looking with out tear down
