EA81 (rebuilt), in a VW bus. VW carb was ugly, FI was cheap. So I stuck it on the engine. Wired it up. Modified the Dist. to fit. Flipped the IAC over so it doesn't bump the dist. verify timing.. Ok.. I verified timing is good. crank a bunch, no start. good spark. pull plug wires, put plug 1 wire a bit away from case, turn engine by hand... good spark right at TDC. ok.. try to run again. No action. next, check fuel. pop off the intake boot, turn it over. No spray into the throttle body. I'm looking at the schematics, and I can't see how fuel gets into idle circuit. with throttle valve closed, the only air entering the manifold is through the bypass valve. the inlet to the manifold is below the throttle valve. The only place I see that fuel enters is from ABOVE the throttle valve... how does gasoline enter manifold at idle? ok, so I'm messing with the throttle body.. put power to START on ECU, fuel pump turns on.. no spray hold start on (about 5 to 7 seconds) all of a sudden I have BIG spray, and it fills the throttle body. I'm not cranking the engine, so I pull the plugs to let it air out. a few minutes later I try again. The same. about 5 seconds of no spray, and suddenly I have a throttle body full of fuel. I wonder if the injector was stuck before, finally became unstuck, and now sticks open? I pull the injector. Put 12v to it. it clicks happily. no longer applying power.... I put air pressure to the intake hole of the injector. I get flow to the output hole. I don't think this is supposed to happen (IE, fuel should flow only if power to injector) Anyone know if injector should allow pressure to go from input to output with no connection to +,-12v There is a screw on top. Not supposed to be able to remove it (tiny tack welds)... I remove the screw. there is a spring under it. there is an o-ring on the screw. the o-ring on the screw seems to be damaged/old. any tips on cleaning or fixing the damaged injector (I'll go get a new- used one at the yard tomorrow) If I get a new o-ring for the spring holder screw inside the injector, should this fix the leak? please email as well as posting (aiiadict at gmail dawt com) Rich

hi, I'd like to know if an EA82 engine (OHC) will bolt to a transmission that an EA81 was previously bolted up to? Are the bellhousings on EA81 and EA82 the same? Rich
