after market stolen radio/alarm now car won't start '84 coupe

[sunlion]

So I'm looking at this coupe, which was stolen years ago, and now won't start since the radio has been stolen. It has/had an aftermarket alarm. The car turns over but won't start. There are aftermarket wires in the dash and trunk. Any thoughts on why this might be?

I can also look for more specific things which may be helpful in solving this mystery.

Regards.

More than likely that after market alarm is the culprit. Probably has some sort of ignition interrupt causing a no spark situation. Start chasing the wires and hopefully you will find whats causing it. I would first check to see if in fact you have spark at the coil, then at the plug wires. If you have spark than check to see if your getting fuel. Basics first, hopefully it's an easy fix. Good Luck.

how long since it last ran?

I think it's been over a year. It was a theft recovery vehicle, sold at auction, but wasn't running then because since the stereo and seats and wheels were stolen and something was done with the alarm system or who knows.

This is on my todo list. My 86 has an Alpine alarm installed that is not operational. Hasn't been used in five years. One day I'll muster up the courage to remove all that wiring.

Get a Bentley (all wiring diagrams are in there) or find another source for your wiring schematics. Grab a multi-meter and start chasing wires. I've done a little wiring work and the Bentley was a big help an easy enough to follow.

What happens when an alarm module decides to die? Yes, it will eventually happen. If you can, remove before that happens.

Most aftermarket alarm circuits are interposed between existing circuit wires (ignition, fuel pump relay, starter solenoid, door lock relays, horn, etc.). It's just a matter of locating and identifying the matching color-coded wires, removing the aftermarket wires connected between them, then resplice the factory wires.

When you're finished, you'll have a bundle of wires to use in other wiring projects and a control unit for a paper weight.

Believe it or not, one of the more useful things about your situation is the fact that the seats are missing. I removed the a/mkt alarm in my '85 as an adjunct to my carpet replacement /interior redo project. The chaise lounge cushion and a couple of thin pillows allowed me some comfort while contorting myself to get head and hands under the dash in order to sort out the wiring in the various harnesses that were hacked into. I could not imagine undertaking the enterprise with the seats in.

Getting accustomed to thinking in German when reading the wiring diagrams is very helpful. I don't have a Bentley manual, so I can't attest to whether their diagrams have been translated, but my Haynes has the German abbrev's (e.g. White is Weiss, ergo it's labeled WS; and Black is Schwartz prounounced shvartz, ergo it's labeled SW) in the diagrams and it can be confusing. For instance, my ignition wiring was interrupted at the ignition switch's rear connector (unplugable) on one of the RT (Rōt=red) leads. It is INDEED an adventure.

Thanks for the tips. Now only if the gentleman that's selling the car would come down to a reasonable price!!!

If I was the gentleman in question, I would rip out the alarm, make it run again and ... raise the price.

Thanks for the tip.

I pulled two alarms and aftermarket remote doorlocks, which included a half dozen relays and about 200 feet of wire. That solved a host of electronic problems including chronic fuse blowing. Pull everything out that was not stock and use that as a starting point.
