1989 240 DL no start

I have a 1989 240 DL that I purchased in August this year. When I bought the car, I went ahead and replaced the plugs and wires since they haven't been replaced in a few years, according to the guy I bought it from.

A month after that, the car began taking awhile to start. Then at the beginning of the month it didn't start at all. It would crank, but not turn over. My fuel pumps were working. I checked my fuel pump relay and that was fine. So I began looking at the ignition system. I've replaced my battery, which was dead, and I've replaced my ignition coil, distributor cab, rotor and the ignition control module. I'm not getting any spark and very lost as to the issue.

Welcome to Matthew's Volvo Site.

The '89 240 should be fitted with an On-Board Diagnostic (OBD) unit in the engine compartment. Have you checked for any fault codes? Instructions for the use of the unit are pinned at the top of the forum.

When you crank the engine does the distributor rotor shaft turn? Easy to check by removing the cap and watching while someone turns the ignition key. If it does not turn is the timing belt OK?

I've tried the OBD and I can't get it to blink. The rotor is turning and the timing belt is in great shape. I just noticed that on the harness that connects to the ignition control module, the number 5 of 5 connections isn't staying in the harness. I've tried bending back the little prong and reconnecting the wire, but it still doesn't stay connected.

I've replaced the wire harness leading to the ignition control module and still no spark. I am at a complete loss here.

When you replaced the coil, distributor cap and rotor did you replace the HT leads or have you tested them? If the lead from the coil to the distributor cap is not working properly you won't get any spark.

I ended finding out that I didn't connect the ECU all the way. When I plugged it in, she started right up.

Thank you for the update.
