Back fires, not starting D-jet?
Posted: Tue Mar 09, 2004 4:55 pm
Hey, all I can get the motor to do is back fire? It pops pretty bad too!
I read through Kjell Nelin article on D-jet fi system for the 914 and the MPS checks out, the temp sensor chks, the cold start chks,the plenum temp sensor chks, the fuel pressure chks. I can hear the pump run and it pumps enough fuel. I can hear the Fuel injectors doing the burr sound when you push the throttle down with the key on. All I know is that it ran when the top shaft came loose in the dist. and pushed the rotor into the cap and it still ran but I opened it to find that because the dwell was off,lol. I fixed the shaft clip and replaced the cap and rotor and set the points then and have static timed it using the light method by turning the dist. with the timing mark in the hole. I did have a broken point plate wire before and fixed that by soldiering a new wire on and it has o resistance and shows continuity to the plate. I cant believe it wont start when it ran with the rotor boring in the cap and before I rebuilt the motor it ran with a hole in the number one cylinder head the size of a screw driver head and sounded like a exhaust leak,lol! She actually ran pretty good just loud,lol! I actually found a new point plate for the dist. and ordered a new blue coil though the old one had continuity and a resistance of 2.5 ohms between - and + and 9.37kohms between - and center which I dont know if is good? Any suggestions? I'm gonna pull the injectors out again even though it ran before in this state and check for leaks and spray? LOL I'm not giving up on her this is a good learning curve for those road side breakdowns,lol! Thanks, Bill
