Question -
I have an '87m Olds Firenza, 2.0l 4 cyl, with a VIN code 1. I replaced the cooling fan relayh, but they sold me the wrong part - only had 4 prongs instead of five. After I installed the wrong relay I tried starting the car and had no ignition. I got the correct relay but I still have no ignition. I have tested the wires into the relay and none of them are hot. All the fuses are okay in the fuse block. I have trace all the wires to the relay back to taped splices, but have not taken the splices apart. They do not look like fusible links, just splices. In thee Haynes book it shows a red wire with a link that should be hot all the time. Where is this link located and are there any other main fuses in this vehicle that are not in the fuse block? I'm stumped on what to do next. Would the wrong relay ruin the ECM? Thanks.
Answer -
Hello Robert,
I sincerely doubt that the wrong relay would do any damage to the ECM.
A fusible link is what I suspect.
Look on the stud on the starter that the big battery cable connects to. If there is another wire on that stud, it should have a fusible link in it.

Hello Van,
Thanks for the location of the links. There are three and all test out to be fine - that is an ohm meter set at times one shows current flow through them. I am stumped because all I did was disconnect the old switch and replace it. Unfortunately I am alone and can't do some tests like check for spark at the plugs. It sounds like I have no fire - the engine just cranks over. If you have any other ideas I would greatly appreciate your input. Thanks.

AnswerHello Robert,
I have a Haynes for several GM's that age, although not that exact one.
But mine shows some of the fusible links at the starter solenoid, which is where I had you looking, but the one for the ignition switch seems to come from the battery cable near the battery. Weather from at the battery, or where the + cable connects to the fuse block is hard to tell, but check both of those places.
