I would take a test light and make sure the GP relay gets power on the other side when the key is turned on...

Jump the contacts on it for 30-40 seconds and then have someone try to start it. If she fires right up then you need to replace it. If it is still a hard start then I would look for air leak problems(hard start after sitting for a couple of hours hot or cold).

Try this before doing much else. Clean the ground wire contact on the controler relay. This is the black wire which is attached to a small bolt on the relay. Clean where it contacts on the bolt and where it contacts the intake manifold. On mine I also ran a separate wire from the black wire bolt to the (-) on the battery to be sure to have a great ground. this seems to have solved a lot of starting problems for me.

30 or 40 seconds is a very long time, I would go for more like 10 or 12 seconds before you try to start it.



The ground wire terminal is usually under one of the bolts that mount the relay/controller to the intake manifold.
