Exclamation Stumps me, re starting problem.

Obviously my vert needs a new motor which is on its way as I can tell by the lumpy running. But it stopped cranking over for two weeks. I tried again tonight and it cranked over and started 4 times since my car wont idle now due to engine failure.

Now without even locking my car or activating my factory alarm it stops the starter from cranking my car. I only tried to restart it after it stalled.

Mechanic says its a 700$ job to rewire the whole alarm system to make it start

The Starter Cut Relay (located next to the Main Relay) is part of the factory alarm system. The role of the relay is to rely on a signal from the alarm via a Light Green/Yellow wire, in this case to allow the relay to be able to start the car properly. There are four wires at the relay, which two are Black/Green. One of these B/G wires is thicker than the other. The thinner gauge B/G wire should have voltage w/key to on. The thicker B/G wire does not have voltage w/key to on, but has voltage w/key to start. If this wire does not have voltage w/key to start then the alarm system is not the cause of the problem. If the thick B/G wire does though have voltage w/key to on then at this relay jumper this thick B/G wire to the Black/White wire in the relay and this will bypass the alarm.

Should read "with key to start."

Just when I need my voltmeter I don't have it. Also if I try to jumper it without checking will it damage it ? How should I jumper it? like at the terminal or somewhere on the wire and take the coating off ?

If the relay were working properly it would take voltage off of the thick B/G wire w/key to start and pass it on to the B/W wire so in jumpering you're just replicating the job of the relay so it won't damage anything. And you jumper at the plug by inserting the jumper wire into the back of the plug related to the necessary two wires.

And the wipers and turn signals should work w/key to on as this verifies that the ignition switch is receiving power. No power at the switch and no start irregardless of the alarm stystem.

Wipers and turn signals work. I tried jumpering it no avail. Is it possible my starter is messed up if it only works sometimes?

Since you don't have a voltmeter it is hard to diagnose your problem. You don't know for sure if the thick B/G wire has voltage w/key to start or not. Knowing this would tell you enough to narrow down the culprit. Could be the starter itself or one of the connections between the ignition switch and the starter or the Interlock switch ( requires the clutch to be depressed to start the car) or the ignition switch itself.
