No Spark..then no fuel Posted by Dana [Email] ![]() ![]() In Reply to: 85 900 turbo no spark, long., Dane, Mon, 6 May 2002 21:51:51 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The LH system and the old CIS system looks to see if you have spark..if not then it shuts down the fuel pump. I believe you should center your attention to the ignition system...i.e.
Ignition control module
Coil
Pickup Sensor
power wiring to these devices.
A wiring diagram for the 85 ignition system is available at;

file names are ignition1.bmp and ignition2.bmp
There should be +12VDC to to the coil when you have the ignition on or start key position....check it from the coil terminal to the car body.
Then look for power voltage to the ignition control module. You should also be able to test the pulse signal voltage (+_/_) out of the pickup per the repair manual. Unless the fuel pump relay is seeing the negative lead of the coil being switched by the ignition control module it will not provide power to the fuel pump....could be a loose connector plug on the side of the distributor with poor connections to the pickup...
