Engine Performance problem
1989 Mercedes Benz 560sec V8 Two Wheel Drive Automatic 110000 miles
Spark should be good now. I got spark from the coil wire while cranking. Hung a plug at cyl#5 got nothing. So I changed the ignition wires along with cap & rotor. I pull the plugs seem like normal wear & color. None were wet. Change spark plugs while I had them out. (All Bosch parts) I crack the fuel feed line at the fuel distributor and got a nice spray. Now here is what's baffling me. I poured some gas in intake via the air disk. I pushed it down so the gas flowed in. DIdn't fire. Also when I crank the engine (air cleaner off) That disk in the intake does not drop down. I believe the fuel distributor is being charged with fuel because when I push down on the disk there is equal resistance all the way down. I do not have access to a fuel pressure gauge set at this time. I do have experience with the VW CIS fuel injection & the old Volvos. I am pretty sure while cranking the engine the disk in the intake should drop a bit. Maybe an inch? PLEASE HELP!
have the same problem?
