Default Ignition



I own a 1978 924 and having a problem I haven't been able to solve! I hope someone can help.</P>


Starts fine runs fine until a go five mile down the road and it start missing and dies! Let it rest a minute starts fine go down the road a little way's and it dies. New fuel pump, acumulator, filter, plugs, wires, distributor pickup, rotor, cap, coil, checked valve clearance. Purchased 6a MSD and coil no help. Went through the normal electrical checks and all checks ok. Replace fuel punp relay. Nothing has cured the problem.</P>


It will sit and run in the driveway all day long and not an issue. Running temp OK, fuel pressure checks ok. Replace ground cables, Cleaned fuel tank and had treated. Running out of idea's fast.<IMG src=smileys/smiley19.gif border="0"> Its electrical !!!! HELP! HELP! HELP.</P>

Hmmm, gotta love that c.i.s. fuel inj. I think you really need to put a guage on the fuel pressure-take the car out and drive it, get it to stall and observe the psi.</P>


You will need to have a guage setup to connect to cis inj cars. It has two connectors. take the fuel line off at the center top port of fuel distributor. connect one side to the line and the other to the dist. thus the fuel will flow through the line. make sure the valve on the guage line is open. diagnosis is as follows:</P>


system psi 5-5.5 bars (valve closed) (80-85psi) - car will want to stall (checked idling.</P>


control psi- small amount less than sys. i think 4 bars or so. look in tech manual.</P>


If pass fuel pressure test, then blame ign.</P>


Been a while since I worked on that system.</P>


Hope this helps Seth</P>
