It’s currently at shop but they work on large diesel equipment, tractors etc. so this is not there area of expertise. This morning he said it may need a new injection control unit, which I could not find and I’m thinking he meant ignition control unit. Anyway I’m on the look out for one. He said that if he had the adapter for the scanner he would be able to tell what was causing the problem. Where could I get on of these? I feel I may be over my head. Any help is greatly appreciated.

Thank you,

Is it not getting fuel?? Or, is it not getting spark??

Before I purchased another Ignition Control Module, I would check the Crankshaft Position Sensor first. If it is defective, you will not get any spark.
Also check the ignition coil.

Good luck,

Dave

On my 77 450sl I had the same problem. If your model has a vacum advance, at distributor, check plastic and rubber lines. mine broke inside rubber line, and took a little checking to discover. replaced plastic line to advance and car started! good luck, Abe g

Push the disk plate in a bit and pour some gas into the intake. Then crank. This will identify if it's fuel or spark.
